A charge.
Atoms are uncharged because for every electron (-ve) there is a proton in the nucleus with a positive (+ve) charge. These cancel each other out.
The charge comes from having an unequal number of electrons and protons. The number of protons always stays the same. That is what tells you what atom it is. Atoms can lose or gain an electron though. If it gains an electron then it becomes negatively charged as it has 1 more electron than protons, if it loses an electron then it becomes positively charged because it has 1 more proton than electrons.

What happens to the structure of an atom to change the atom into an ion?
The loss or gain of electrons transform an atom in an ion.
What is an atom with an electrical charge on it called?
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 ."
Chemical formula of a fluoride atom?
'Fluoride atom'. ???? The fluorine ATOM is 'F' The fluorine molecule is 'F2'. The Fluoride ION is 'F^-' NB When an atom becomes a charged species, it is no longer an atom , but an ION. The suffix '--ide' indicates it is an ion, not an atom. So 'Fluoride atom' is a nonsense. It is either 'Fluoride ion' or Fluorine atom'.
Losing or gaining electrons makes an atom a?
Ion
What do you call a neutrally charged atom?
A neutrally charged atom is just called an atom. This is when the atom's number of electrons is equal to its number of protons, canceling out all far-field electromagnetic effects. If the atom has a net charge, it is then called an ion.
What does a fluoride ion have in common with a neon atom and a sodium ion?

What a ion?
An ion is a positively or negatively charged atom or molecule.
Is an ion atom with a charge?
An ion is an atom with a positive or negative charge.
Is sulfur an atom or An ion?
ion
What happens to the structure of an atom to change the atom into an ion?
The loss or gain of electrons transform an atom in an ion.
An atom is called an ion if there?
An atom is called an ion if there is a charge on it - positive or negative.
How can you tell if an atom is an ion?
If the number of protons and neutrons are the same, its an atom, if not its an ion
What is the difference of an atom or an ion?
A ion is an electrically charged atom, positive or negative.
What is an atom called when it has a charge?
When an atom gets charged it is called ion.
Smallest is a atom or ion?
atom
What is an atom with an electrical charge on it called?
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 ."
