An atom of a different element.
a new element
Often there are the same number of electrons as there are protons. Exceptions to this are called ions, which have gained or lost an electron (can't be a proton lost or gained, that would change the element).
They are equal to the Proton number, giving the atom a net charge of 0.If electrons are gained or lost, then it's not an atom anymore, it's an Ion.
An atom that has gained an electron becomes a negatively charged ion.
the number of protons in an atom is what determines which element the atom is. So if an atom "lost" a proton, it would become another element entirely.
An atom has no charge. An ion is an atom that has either gained or lost an electron giving it a charge. An atom that has gained an electron is called an anion and is negative, while an atom that lost an electron is called a cation and is positive.
An atom has no charge. An ion is an atom that has either gained or lost an electron giving it a charge. An atom that has gained an electron is called an anion and is negative, while an atom that lost an electron is called a cation and is positive.
It forms a new atom.
An ion
Just electron
Generically an "ion", specifically gained an electron an "anion", lost and electron a "cation".
