This is nuclear physics.
When an atom gains a proton it is 'fusion'.
When an atom loses a proton it is 'fission'.
e.g. Using heavy hydrogen (deuterium)
[2/1]H + [2/1] = [4/2]He
This is very simple nuclear fusion, which is going on in the Sun.
Using Uranium - 236
This disintegrates into plutonium and a neutron ; this is nuclear fission and goes on into nuclear reactors (in power stations), on Earth or Atom Bombs.
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.
This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
covalent/ionic bonding.
An atom that gains or loses electrons is called an ion. When an atom loses electrons, it becomes positively charged and is called a cation. When an atom gains electrons, it becomes negatively charged and is called an anion.
Ion. Any atom that loses or gains an electron becomes an ion.
An atom that loses electrons becomes a positively charged ion called a cation. An atom that gains electrons becomes a negatively charged ion called an anion.
When an atom loses electrons, it becomes a positively charged ion called a cation. When an atom gains electrons, it becomes a negatively charged ion called an anion.
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.
covalent/ionic bonding.
Ion. Any atom that loses or gains an electron becomes an 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.
When an atom loses or gains electrons, it becomes an ion.
