It is likely the neutral atom has 6 protons and 6 electrons; while the negatively charged atom has 7 or more electrons.
The mass of an atom, commonly known as the atomic mass is determined by the number of protons and neutrons as electrons have a very low mass.
This means two atoms can have the same number of protons and neutrons, but a different number of electrons, which would make the atom be charged negatively or positively.
Based on this, if there are two atoms, each with 6 protons but one of these is negatively charged it is because the second atom has 1 or more extra.
Neutral atom:
- This atom has 6 protons and an unknown number of neutrons located in the nucleus.
- This atom has 6 electrons that orbit the nucleus.
- The first energetic level will include 2 electrons while the second energetic level will include the 4 remaining electrons.
Negatively-charged atom:
- This atom has 6 protons and an unknown number of neutrons located in the nucleus.
- This atom has 7 or even more electrons that orbit the nucleus.
- The first energetic level will include 2 electrons while the second energetic level will include up to 8 electrons.

<u>Halogens are reactive because:</u>
They have high electronegativity and also high nuclear charge. So, they are reactive and also gain an electron when they react with other elements.
Since they are very reactive, halogens are very harmful to living organisms. Some of the halogens are fluorine, chlorine, bromine, iodine, astatine. These are mostly non metals. Fluorine is one of the most reactive gas and also very toxic gas. When Fluorine reacts with glass along with small amounts of water, it forms silicon tetra fluoride (SiF4). Hence fluorine should be handled with substances like the inert organofluorine compound Teflon.
<span>When two or more substances are mixed together but not chemically joined they are called as mixtures. Therefore, it is only a physical change taking place.
