Electrons are negatively charged.
When an atom gains an electron it gains this negative charge, and so it becomes negative.
When it loses it again it has lost that negative charge and becomes more positive.
Boron becomes positive when it loses electrons. Boron has three valence electrons and tends to lose these electrons to achieve a stable electron configuration similar to a noble gas. When boron loses its three valence electrons, it forms a B3+ ion, which has a positive charge.
When atoms lose or gain an electron, they become ions. If an atom loses an electron, it becomes positively charged and is called a cation. If an atom gains an electron, it becomes negatively charged and is called an anion.
When atoms either lose or gain electrons they are referred to as ions.
Atoms balance out their charges by having the same amount of protons as electrons. Since protons are positive, and electrons are negative, losing an electron increases the positive charge of an atom. This makes it an ANION. If an atom were to gain an electron, it would make it a CATION.
When an atom loses an electron, it becomes positive (Since you're taking away something that is negative). It would not become an ion, it would become a cation.

it becomes a charged ion loose = positive gain= negative
it gains or acquires a charge either positive or negative so when it gains energy, it aquires a negative charge then when it loses energy, it aquires a positive charge
if a neutral atom donates an electron it will gain a positive charge. This is due to electrons having a negative charge.
Electrons have a negative charge, so they are usually written as "e-". When an atom loses an electron, the net charge on the atom increases.Suppose a hydrogen atom is hanging out (note that hydrogen is diatomic, but ignore that part for now) and somehow loses its electron. The electron will get taken up by something else with a positive charge (opposite charges attract each other). In general it would look something like the following:H -> H+ + e-This positively charged hydrogen (H+ on the products side) is considered a Cation (cation's are positive as they have a T in them that looks like a +, anions don't have a T so they are what we call negatively charged anions).
1) depends up on the the element basically: metals (electropositive elements) can donate nonmetals can(electro negative )elements can accpect the electrons 2)the result: if an atom losses the electron it becomes positively charged normally metals donate the electons and become + charged.
When atoms lose or gain an electron, they become ions. If an atom loses an electron, it becomes positively charged and is called a cation. If an atom gains an electron, it becomes negatively charged and is called an anion.
if a substance loses one or more electrons it becomes positively charged and when it gains an electron it becomes negatively charged
An electron has a negative charge. If an atom loses an electron it creates an ion with a positive charge. If an atom gains an electron it creates an ion with a negative charge.
When a sodium atom loses a valence electron, it becomes a positively charged ion called a sodium ion (Na+). When a sodium atom gains a valence electron, it becomes a negatively charged ion called a sodium ion (Na-).
== == == == The answer is an ionic atom.== ==when it gains an electron, it acquires partial negative charge and it's at.weight increaseswhen it looses electron; it acquires partial positive charge and at.weight decreases
electrons... and thus one unit of negative charge....
