If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion.

Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.

An atom that has a positive or negative charge is called: an ion. If an atom gains an electron, the overall electrical charge of the atom becomes: negative.

Structure: Our current model of the atom can be broken down into three constituents parts – protons, neutron, and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge.

The majority of an atoms’ mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom’s constituent particles, with a mass of 9.11 x 10-31 kg and a size too small to be measured by current techniques.

Electron has the least amount of mass in an atom. The mass of the electron is almost negligible in an atom. This electron is revolve around the nucleus.

Electrically neutral atoms can exist with no electrons. So an atom can’t have no electrons as it, by definition has protons and to be neutral must have electrons. You can have an ion, such as a hydrogen ion (you might call it a proton).

There is only one stable atom that does not have neutrons. It is an isotope of the element hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom. All other stable atoms contain some number of neutrons.

As it turns out, atoms do have a finite lifespan, because protons have a finite lifespan. Eventually, protons will decay into short lived subatomic particles. This will happen in 10^32 years. Or 100 nonillion years.

Of course, germs are tiny and impossible to see without some tool to amplify our senses, BUT they are huge compared to the atoms that make up those germs. Those atoms are also matter and are even smaller and harder to see than germs.

Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element.

Many atoms consist of a positively charged nucleus consisting of protons and neutrons surrounded by a cloud of electrons charged negatively. An atom is any particle of matter at its most basic level which contains at least one proton. Here are some examples of the atoms: hydrogen (H) neon (Ne).

Atoms are made up of three kinds of smaller particles, called protons, neutrons and electrons. The protons and neutrons are heavier, and stay in the middle of the atom, which is called the nucleus….Atom.

An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. Each electron is negatively charged. The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons.

The term “atom” comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks.

Meaning of atom in English. the smallest unit of any chemical element, consisting of a positive nucleus surrounded by negative electrons.

1) The nucleus of an atom consists of neutrons, protons and other particles. 2) Two atoms of hydrogen combine with one atom of oxygen to form a molecule of water. 3) He patented the idea that the atom could be split. 4) He could not get up an atom of sympathy for her.

Short Answer. There are approximately 7 x 1027 atoms in the average human body. This is the estimate for a 70 kg adult human male. Generally, a smaller person would contain fewer atoms; a larger person would contain more atoms.

Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you.

The smallest particle of an element that retains all the chemical and physical properties of the element. Anatom can exist either alone or in combination with other atoms in a molecule. Atoms are made up of protons, neutrons, and electrons.

The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. When people draw pictures of atoms, they show the electrons like satellites spinning round the Earth in orbits.

But when it comes to the word atom, we have to go to ancient Greece of 400 B.C. And there was a brilliant philosopher named Democritus, and he proposed the Greek word atomos, which means uncuttable. And so as he explained, all matter was eventually reducible to discrete, small particles or atomos.

In other words, there is a lower limit to the division of matter beyond which we cannot go. Atoms were impenetrably hard, meaning they could not be divided. In Greek, the prefix “a” means “not” and the word “tomos” means cut. Our word atom therefore comes from atomos, a Greek word meaning uncuttable.
