What is a neutral atom that gains or loses electrons?

A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.


An atom that has lost or gained electrons is an?

an ion


What is the resulting charge of a surface that gains electrons?

Electrons have a negative charge. Therefore, an atom having extra electrons is a negative ion.


What is the charge of a N ion?

The charge of a nitrogen ion (N) can vary depending on the number of electrons it has gained or lost. Typically, a nitrogen ion can have a charge of -3 when it gains three electrons or +3 when it loses three electrons.


When an atom gains or loses electrons it has an electrical charge. It is known as?

It is called an ion.


The charge an object has when it has gained electrons?

An atom that gains electrons and therefore forms a negative ion is known as a?

If an atom gains an electron it has a net negative charge and is known as an anion. A ion has a single atom which is atomic or monatomic.


How does a positive ion become a neutral atom?

A positive ion can become a neutral atom by gaining electrons. When a positive ion gains one or more electrons, it becomes neutral because the negative charge of the electron(s) cancels out the positive charge of the ion.


What is the electric charge of an oxygen atom that gains 2 electrons in an oxygen ion?

An oxygen atom has 6 protons and 6 electrons, giving it a neutral charge. When it gains 2 electrons to form an oxygen ion, it will have 8 electrons in total. Since it now has 2 more negatively charged electrons than positively charged protons, the oxygen ion will have a charge of -2.
