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.
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.
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.
covalent/ionic bonding.
Ion. Any atom that loses or gains an electron becomes an ion.
A neutral atom that gains or loses electrons is now an ION. If it loses electrons to become M^(n+), then it is a CATION. If it gains electrons to become X^(n-), then it is an ANION. NB Atoms that gain or lose electrons are no longer atoms , but IONS.
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 ION . Metal (M) ionises ( loses electrons) M(g) = M^(n-) + ne^(-) M^(n+) is a CATION . Non-metal (X) has electron affinity ( gains electrons) X(g) + ne^(-) = X^(n-) X^(n-) is an ANION .
When an atom loses or gains electrons, it becomes an ion.
an atom that gains an electron becomes a negative ion, called an anion.
