One electron
An electron has a charge of -1. When a Sodium (Na) atom loses one electron, it loses a negative and becomes a stable Sodium ion with a charge of +1.
1+
The charge of an atom as a whole is zero. We can give the charge of a nucleus. If any electron, negatively charged one, go out of atom then the atom gets positive charge and it is named as positive ion. Same way if excess electrons get cling with the neutral atom then the atom becomes a negative ion.
it gets a postive charge hope this helps good luck
When an atom gains an electron the no of negatively charged particles increases inside the atom and the atom gets negatively charged.
An atom will become Negative if it gains an electron and it will be an Anion.If it loses an electron it will be Positive and it will be a CationLearn & Enjoy
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.
If an atom loses 3 electrons, it gets a charge of +3. (One positive charge for every electron lost). If an atom loses 2 electrons, it gets a charge of +2.
Bromine can form a -1 ion by gaining one electron to achieve a stable electron configuration. This allows bromine to attain a full outer electron shell, similar to the electron configuration of a noble gas, making it more stable.
Electrons have negative charge. So when electrons is lost from an atom, the atom gets positive charge.
it gets positive charge
The negative charge increases by 1. So it is -1
