The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral. Therefore, all things are made up of charges. Opposite charges attract each other (negative to positive). Static electricity is the result of an imbalance between negative and positive charges in an object.

Most electric charge is carried by the electrons and protons within an atom. Electrons are said to carry negative charge, while protons are said to carry positive charge, although these labels are completely arbitrary (more on that later). Conversely, two protons repel each other, as do two electrons.

Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed. Electric charges are of two general types: positive and negative. Two objects that have an excess of one type of charge exert a force of repulsion on each other when relatively close together.

Electrons

neutron: A subatomic particle forming part of the nucleus of an atom. It has no charge. It is equal in mass to a proton or it weighs 1 amu.

When an object gains electrons, it has a surplus of electrons and is said to have a negative charge. When an object loses electrons, it has a shortage of electrons, it has a shortage of electrons and is said to have a positive charge.

hello friend ☺️!!!!! Atoms of all elements – except for most atoms of hydrogen – have neutrons in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons have no charge – they are electrically neutral.

Electron: A negatively charged particle found circling or orbiting an atomic nucleus. An electron, like a proton is a charged particle, although opposite in sign, but unlike a proton, an electron has negligible atomic mass.

All charged particles come in one of two types: positive and negative (or plus and minus). The minus particles are the electrons, and the plus particles are the much heavier protons which are buried deep in the nucleus. As the distance between the charges is increased, the force quickly becomes smaller.

In physics, a charged particle is a particle with an electric charge. It may be an ion, such as a molecule or atom with a surplus or deficit of electrons relative to protons. It can also be an electron or a proton, or another elementary particle, which are all believed to have the same charge (except antimatter).

An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.

That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart. Similarly, a negatively charged object will exert a repulsive force upon a second negatively charged object. Objects with like charge repel each other.

The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral. Therefore, all things are made up of charges. For example, if you rub your shoe on the carpet, your body collects extra electrons.

Electric Charge

• protons are positively charged.
• electrons are negatively charged.
• neutrons have zero charge.

Description. Atmospheric electricity is always present, and during fine weather away from thunderstorms, the air above the surface of Earth is positively charged, while the Earth’s surface charge is negative.

Answer: Friction. Explanation: Friction is what causes fire to start when you rub two sticks together, as these warriors from a Masai tribe in Kenya are doing. Friction is the resistance to motion of one object moving relative to another.

Friction is the resistance of motion when one object rubs against another. Anytime two objects rub against each other, they cause friction. Friction works against the motion and acts in the opposite direction. Friction and Energy.

Answer: When two different materials are rubbed together, there is a transfer of electrons from one material to the other material. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer).

To start walking, you push back with your foot on the floor. Without friction, your foot would slide back, moving back relative to the floor, as shown in Figure 5.2. Static friction opposes this motion, the motion that would occur if there was no friction, and thus static friction is directed forward.

Friction manifests as heat energy generally and sometimes as noise. When objects are moving against each other, there is a generation of kinetic energy. The biggest disadvantage of friction is wear and tear that happens as a result of friction. …

Without friction, a car’s tires could not push against the ground to move the car forward, and the brakes could not stop the car. Without friction, a car is useless. However, friction can also cause problems in a car. Friction between moving engine parts increases their temperature and causes the parts to wear down.

Three disadvantages of friction are :

• Friction produces heat which damages the moving parts of a machine.
• Friction produces wear and tear on the contacting surfaces. This reduces the life of machine parts, tyres and shoe soles.
• A lot of energy is wasted in overcoming the friction before an object starts moving.

The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. The nucleus of an atom contains protons and neutrons. Protons and neutrons have nearly equal masses, but they differ in charge.

Atoms start out with the same number of negative charges (electrons), and positive charges (protons). Removing electrons would leave the atom with more positives than negatives, and we call this a positive ion (An ion is a charged atom). Conversely, adding electrons to an atom would result in a negative ion.

This is called polarization. Polarization occurs whenever electrons within a neutral object move because of the electric field of a nearby charged object. It occurs without direct contact between the two objects.

Negative charges can move freely from one object to another. Protons and neutrons never move from object to object. The energy that comes from these charged particles is called electrical energy. When the negative charges move to a neutral object, an electric charge builds up on both objects.

In order to charge an object, one has to alter the charge balance of positive and negative charges. There are three ways to do it: friction, conduction and induction.

Electric charges are of two general types: positive and negative.

Any particle, whether an atom, molecule or ion, that contains less electrons than protons is said to be positively charged. Conversely, any particle that contains more electrons than protons is said to be negatively charged.

Infobox references. The chloride ion /ˈklɔːraɪd/ is the anion (negatively charged ion) Cl−. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents.

When we say “chlorine wants to gain one electron”, we speak of the radical atom. Chlorine as a free radical, Cl⋅ , is the chlorine atom that we say has 7 valence electrons and wants its 8th to form an octet. So, Cl⋅ , chlorine radical, is less stable, and Cl− , chlorine ion, is more stable.

Chlorine (Cl), chemical element, the second lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.
