When ions are formed atoms can lose or gain electrons. If they lose and electron they become positively charged. This is typical for [although not exclusive to] metals in chemical reactions. If they gain an electron the become negatively charged. This is typical for [although not exclusive to] non-metals in chemical reactions.
Electrons can also be knocked out of an atom by radiation. Again the atom would be come positively charged under these circumstances.

Can atoms lose or gain atoms to form elements?
No. Atoms of an element lose or gain electrons to form ions.
When atoms lose or gain electrons they from?
When atoms lose or gain electrons, they form ions. These are charged particles.
What 2 way are ions form from atoms?
1. Gain an electron. 2. Lose an electron.
Atoms gain or lose electrons to form ions?
They can do both to form ions. An ion simply means that there is an uneven distribution of charge, so it can be positive or negative.
How do positive and negative ions forms?
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Does N and Br gain or lose electron?
Nitrogen atoms gain 3 electrons and form the nitride ion, N3-. Nitrogen atoms also form covalent bonds where they share 3 electrons and do not become ions. Bromine atoms gain 1 electron and form the bromide ion, Br-. Bromine atoms also form covalent bonds when they share 1 electron and do not become ions.
When atoms or molecules gain or lose electrons they can be best described as what?
Ions
What are ions and under what conditions are they produced?
When atoms gain or lose electrons.
Hat are charged particles the form when atoms gain or lose electrons?
What are charged particles that form when atoms gain or lose electrons
Why do atoms change to ions?
Because they either lose or gain valence electrons.
How does a cation form?
Cations form when atoms lose electrons, they gain a positive charge as a result.
How are ions made?
Ions are electrically charged particles formed when atoms lose or gain electrons. They have the same electronic structures as noble gases. Metal atoms form positive ions, while non-metal atoms form negativeions. The strong electrostatic forces of attraction between oppositely charged ions are called ionic bonds
