the different properties are protons, electrons and neutrons here is a picture
Yes, different isotopes of an atom have the same number of protons and electrons, so they have the same chemical properties. However, they have different numbers of neutrons, giving them different masses.
Isotopes of an atom does retain the properties of the atom. This is discrete in units of matter.

Allotropes
Because the number of protons and electrons remain unchanged.
It is the distribution of electrons of an atom in different shells. It helps to understand various physical and chemical properties of an element.
Various types of bonds that they either do or do not form with other atoms
Isotopes are found in the nucleus of an atom. They are atoms of the same element with the same number of protons but different numbers of neutrons. The different isotopes of an element have the same chemical properties but different physical properties.
They are two different elements composed of two different types of atom. They have different chemical and physical properties.
An isotope is an atom that has an irregular number of neutrons in its nucleus. Since it has the same number of protons as a normal atom, they still have the same chemical properties and are still technically the same thing, but since the atomic weight is different they have slightly different physical properties.
They have different properties because the element that make up these compounds are different, water is made up of 2 hydrogen atoms, and 1 oxygen while table salt is made of a sodium and a chlorine atom. These different combinations make up different properties. Why the elements that make up these compounds have different properties however is a different question.
An example of an atom with properties different from an ion of the same element would be fluorine. Fluorine in its atomic form (F) is a highly reactive gas, while an ion of fluorine (F-) is a stable, non-reactive anion. This is due to the difference in the number of electrons in each state, affecting their reactivity.
