∙ 11y agoAn electron can be gained or lost from an atom for two reasons:
1. A random number of atoms can be close together will have electrons bumping into each other. Since all electrons have a negative charge, they will have magnetic effects on one another, and will push eachother of the outer shell of their atoms and into different ones.
2.Two or more atoms can bond together so that both atoms in turn have a balanced number of electrons.

∙ 11y agowhen an atom loses an electron, it loses a negative charge and becomes a positive ion. when an atom gains an electron, it gains a negative charge and becomes a negative ion.
methods in which an atom can gain energy
In normal chemical reactions, electrons are easier to add or remove from an atom. Protons and neutrons are never added or removed in normal chemical reactions. Only nuclear reactions can change the numbers of protons and neutrons, such as radioactive decay. However, even then the protons and neutrons are not added or removed in the way that electrons are.
The positivity and negativity of an ion is determined by the number of electrons compared to that of protons. If there are more electrons than protons in the ion, it is considered negative. It becomes negative by gaining electrons, which can happen a number of ways. Simply put, most often it gains electrons by pulling them off of other elements and molecules. The more electronegative an element is, the easier it is for it to do this. Elements are most stable in their "octet" configuration where all of the available spots in an orbital are filled. Elements with less than a perfect octet will rip electrons off of other things.
one way is when electrons are are share between two atoms another is when an atom loses or gaons an electron
They gained power in order to vote for the people. They lose some because they can be voted out if the people do not like their decisions.
Carbon is the "utility player" of chemistry, and can bond in many different ways with other elements. It generally shares electrons covalently with other non-metals, usually hydrogen, oxygen, and nitrogen. It doesn't typically lose or gain them (but can in certain situations.)
IF it donates an electron -then atom gains positive charge and if it accepts an electron then it acquires negative charge. the mass of an atom is dependent on protons and neutrons in the nucleus and electrons decide the charge of an atom
when an atom loses an electron, it loses a negative charge and becomes a positive ion. when an atom gains an electron, it gains a negative charge and becomes a negative ion.

Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
