Barium has two electrons in its outermost shell, electrons carrying a negative charge. When the Barium atom becomes an ion, these two electrons are lost. Now the Barium atom has more protons than electrons, meaning a net positive charge of 2.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
An atom that gains three electrons will become an ion with a 3- charge.
An ion is an atom with a positive or negative charge.
well The electrons on that shell have nowhere to go so they jump off and become ionised
when an atom loose electron it become negative ion and when it gains electron it become positive ion
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
An atom of potassium-41 becomes a potassium ion with a plus charge by losing one electron. Potassium-41 has 19 electrons in its neutral state, but when it loses one electron, it becomes a potassium ion (K+) with a plus charge and 18 electrons.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
An atom that gains three electrons will become an ion with a 3- charge.
The oxygen atom would have a charge of -2 after gaining two electrons to become an oxygen ion.
IONS OS ION ^^A charged atom is called an ion
An ion is an atom with a positive or negative charge.
When a chlorine atom ionizes, it gains one electron to become the chloride ion with a charge of -1.
This atom become a cation (positive charge).
It becomes an ion. Specifically a cation.
The resulting oxygen ion has a charge of -2.
well The electrons on that shell have nowhere to go so they jump off and become ionised
