Q. Which element has 2 electrons in an atom?
Helium
Q. How do you find the amount of electrons in an element?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Q. How many electrons do each element have?
The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons….2.1 Electrons, Protons, Neutrons, and Atoms.

| Number of Electrons in Each Shell | First | 2 |
Q. How many electrons are there in an atom of carbon?
2, 4
Q. How many electrons are in a oxygen atom?
2, 6
Q. How do you know how many rings an atom has?
Horizontal rows on the Periodic Table are called periods. – The row number tells you how many energy levels, or rings, the element has. – Elements in the same row have the same number of rings.
Q. What two particles are found in the center of an atom?
In the middle of every atom is the nucleus. The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus.
Q. What parts go into the center of an atom?
Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom.
Q. What atom is the smallest?
helium
Q. Is there anything smaller than atom?
In physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles. Particle physics and nuclear physics study these particles and how they interact.
Q. What is the smallest matter in the world?
quarks
Q. Do atoms have a lifespan?
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.
Q. Can atoms age?
Atoms don’t age. Atoms radioactively decay when a lower-energy nuclear configuration exists to which they can transition. The actual decay event of an individual atom happens randomly and is not the result of the atom getting old or changing through time. Atoms are too simple to wear down, corrode, or steadily change.
Q. What happens to our atoms when we die?
When we die, our atoms will disassemble and move off to finds new uses elsewhere – as part of a leaf or other human being or a drop of dew. Atoms themselves, however go on practically forever.
Q. How old are the atoms in our body?
Every atom in your body is billions of years old. Hydrogen, the most common element in the universe and a major feature of your body, was produced in the big bang 13.7bn years ago.
