Every element has a specific amount of protons and neutrons in its nuclues. If an atom has more protons and neutrons than another element, it is heavier.

How many grams are there in one mole?

It depends on the element. One mole is 6.02 × 1023 atoms, which has a certain mass. But (for example) one hydrogen atom is going to weigh less than a lithium atom. Therefore, two samples of the two elements of 6.02 × 1023 atoms will weigh differently.

Is a atom an element?

An atom is an element. Every atom has a certain amount of protons, neutrons and electrons and these are what define which element that atom is.


Why the mass number of the same atom of an element is not constant?

Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.


Can to different elements contain the same number of protons?

No, the number of protons defines what element an atom belongs to. If two atoms are of different elements then they have different number of protons.


Why are electrons in an atom involved in bonding?

they have a natural tendecy to become stable that's why different elements under different conditions react to form different elements or compounds.


What do you call an atom of the same element that has a different numder of neutrons?

Isotopes of elements have different atomic mass'.
