An electron.
a particle with a negative charge in an atom is an electron
A charged atom is called an ion.If it has more protons then electrons, it has a positive charge.If it has more electrons than protons, it has a negative charge.
An atom with positive charge is cation.An atom with negative charge is anion.
The negative charge in an atom is called an electron. Electrons are subatomic particles that orbit the nucleus of an atom and are responsible for carrying electrical current and forming chemical bonds.
An atom is called an ion if there is a charge on it - positive or negative.
It's an ion. Cation for positive and anion for a negative atom
A unipositive or uninegative monoatomic ion.
An atom with an electrical charge is called an ion.
a cation atom!
A particle with a negative electrical charge is called an electron.
An atom with a charge is called an ion. An ion forms when an atom gains or loses electrons, resulting in a positive or negative charge. Positively charged ions are called cations, while negatively charged ions are called anions.
An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
