|
|
The number of electrons changes too
|
|
|
Usually nothing happens, unless the atom is radioactive
|
|
|
The atomic nucleus explodes
|
|
|
It becomes a completely different atom, with different properties
|
Detailed explanation-1: -Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom’s atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
Detailed explanation-2: -Transmutation or nuclear transmutation is a process that involves a change in the nucleus of an atom. When the number of protons in the nucleus of an atom changes, the identity of that atom changes as it is turned into another element or isotope. This transmutation process can be either natural or artificial.
Detailed explanation-3: -If an atom has unequal numbers of protons and electrons, it will be charged and is called an ion. The reaction below shows how ions form.
Detailed explanation-4: -Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
Detailed explanation-5: -Differing quantities of protons, neutrons, and electrons cause the atom to have differing chemical properties, which determine what element that atom is. Atoms are unimaginably small, and their nuclei are 1000 times smaller.
