All the above
Yes, the element changes to compound when atoms of it changes because compound is made up of different types of element and the element is made up of different types of atoms when the atoms are changed the element also changes and different types of elements are made due to this the element is changed to a compound.
When an element undergoes nuclear transmutation the result is a completely different element or isotope. All transmutation occurs through decay or nuclear reaction.
When the number of protons in an atom changes, the identity of the element changes because the number of protons determines the element's atomic number. If the number of protons changes, the atom becomes a different element. This process is called nuclear fusion or fission.
Because the atomic number is the number of protons in an element. If you change the atomic number you will have a completely different element. The mass number changes because the number of neutrons is different.
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
The element is completely changed
Yes, the element changes to compound when atoms of it changes because compound is made up of different types of element and the element is made up of different types of atoms when the atoms are changed the element also changes and different types of elements are made due to this the element is changed to a compound.

An element can only change if the number of protons in its nucleus changes. It is possible to make one kind of element into another, but all these processes can be accomplished only by nuclear means. Gold can be changed into another element in a physics lab, but only with the use of a nuclear reactor or an accelerator of some kind. Any element can be changed into another element, but only by nuclear means.

Protons. Protons determine the atomic number which in turn determine what the element is, so if the number of protons is changed the element is changed. Isotopes have a different number of neutrons and Ions have a different number of electrons than the original atom.
Neon is an element, and a noble gas to boot (noble gases have completely filled electron shells); it hasn't changed a bit since it was forged in the hearts of stars.
Chemical Reaction
It's called transmutation. There are two types of transmutation. Natural transmutation is when an element naturally changes into another element. Artificial transmutation is when an element is forced to change into another element, usually done in a laboratory setting.
Because the atomic number is the number of protons in an element. If you change the atomic number you will have a completely different element. The mass number changes because the number of neutrons is different.
The ending of the second element is changed to -ide
A pure element (on an atomic scale) is a series of the same atoms (same amount of electrons). Elements in compounds are fused to each other meaning that their amount of electrons may have changed and they may have a different charge.
