It doesn't really "become" charged. An electron is always charged, and it can only have a charge of -e where value of elementary charge e is 1.602 * 10-19 C as found first by Millikan with his famous oil drop experiment
By gas particles I suppose you mean gas molecules? These become charged when ionized, when an electron is stripped off.
A negatively charged atom is called an electron.
No, its negatively charged.
Protons and electrons but strong forces keep them apart
A negatively charged partical is an electron.
since an electron is negatively charged, adding an electron to an atom will cause it to become negatively charged.
The atom needs to gain an electron so it has more than the protons Hope I helped
When an atom loses an electron and becomes negatively charged we refer to it as a positive ion
yes
If it looses an electron, it becomes positively charged. If it gains one, it becomes negatively charged. These charged species are collectively called ions.
Since electrons are negatively charged, a nonmetal which gains an electron will also become negatively charged.
It become an ion, positively charged when it loses an electron (called a cation, e.g. Na+) or negatively charged when it gains an electron (called a anion, e.g. Cl-).
By loosing and gaining an electron.
It becomes a negatively charged ion.
electron
It will become negative by electron addition, because electrons are negatively charged, -1. It is then called an ion.
When an atom gains or looses a valence electron it becomes a charged particle called an ion
