they contain electrons, which are negatively charged and revolve at high speed around the nucleus of an atom. the first shell (the one nearest to the nucleus) can hold a maximum of 2 electrons. the second shell can hold a maximun of 8 electrons. If there any remaining electrons they will go on the third shell. the third shell can hold a maximum of 18 electrons. the shells closest to the nucleus (inner shells) must contain their maximum number of electrons before attempting to fill the energy levels to a higher energy.

What is an atom shell?
electron shells are like the orbits of electrons around the protons and neutrons the atoms can have 1-3 shells
How many outer shell electrons does iodine have?
The outer most electron shell of iodine atom contains 7 electrons.
How many electrons are in each of the first two shells if an atom contains eight electrons?
The first shell can have 2 electrons, the second shell has 8 electrons and the third shell has 8 electron also. No matter what, electron fill up the first shell and then move into the next shell and then the next one. To answer the question, the first shell would have 2 electron and then the second shell would have six.

What is the octet electrons?
An octet of electrons is when the outermost electron shell of an atom contains eight electrons.
The particles that make up an atom are?
Nucleus, which contains protons and neutrons Energy Shell/Electron Cloud, which contains electrons
What is the overall of an atom?

When compared with the energy of an electron in th first shell of a carbon atom the energy of an electron in the second shell of a carbon atom is?
greater
How many electrons does each hydrogen atom have in its valence shell?
Hydrogen doesn't really have a valence shell. It has one electron only.
Why does chlorine exist as Cl2 rather than a single atom?
A lone chlorine atom has 7 electrons in its outer shell or valence shell, with 3 pairs and 1 unpaired electron. This is an unstable configuration. A stable outer shell contains 8 electrons in 4 pairs. So, two chlorine atoms will form a covalent bond, each sharing its unpaired electron. This bond forms a full pair of electrons that is shared between the two atoms, effectively giving each atom a stable shell of 8 electrons.
