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.

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'.
What is formed when an atom gains or loses an electron?
An atom forms an ion when it gains or loses an electron. If an atom gains an electron, it becomes a negatively charged ion (anion). If an atom loses an electron, it becomes a positively charged ion (cation).
How does a hydrogen ion change into an atom?
A hydrogen ion can change into an atom by gaining an electron. When a hydrogen ion, which is essentially a hydrogen atom that has lost its electron, gains an electron back, it will become a neutral hydrogen 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 ."
What happens to the structure of an atom to change the atom into an ion?
An atom becomes an ion by gaining or losing electrons. When an atom loses electrons, it becomes a positively charged ion (cation) as it has more protons than electrons. On the other hand, when an atom gains electrons, it becomes a negatively charged ion (anion) as it has more electrons than protons.
What does a fluoride ion have in common with a neon atom and a sodium atom?
what does an atom have in common with an 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.
What is an atom called when it has a charge?
An atom with a charge is called an ion. If the atom gains electrons, it becomes a negative ion (anion), while if it loses electrons, it becomes a positive ion (cation).
Is sulfur an atom or An ion?
ion
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
An atom is called an ion if there?
An atom is called an ion if there is a charge on it - positive or negative.
What is the difference of an atom or an ion?
A ion is an electrically charged atom, positive or negative.
Smallest is a atom or ion?
atom
When an atom loses an electron it loses a?
Removal of an electron from an atom leaves a positively charged ion.
What is one atom ion called?
A one-atom ion is called a monatomic ion. It is formed when an atom gains or loses electrons, resulting in a net positive or negative charge.
