When a atom gets a positive or negative charge which subatomic particle number has changed?
When an atom gains a positive charge, it loses an electron(s), resulting in more protons than electrons. When an atom gains a negative charge, it gains an electron(s), resulting in more electrons than protons.
What is atom that has gained an electron to form a charged particle?
An atom that has gained an electron becomes a negatively charged particle called an anion. This occurs when the atom gains an extra electron and now has more electrons than protons, giving it a net negative charge.
If valence electrons are gained or lost the atom becomes a charged particle called what?
It becomes an ion. There are two types of ions- if it loses an electron, it gains a positive charge, becoming a "cation". If it gains an electron, it takes on a negative charge and becomes an "anion".
What is the result of an atom that gains or loses an electron?
An atom that gains an electron becomes negatively charged and is called an anion. An atom that loses an electron becomes positively charged and is called a cation.
What happens when an atom gains an electron when it loses an electron?
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-).
