2) Atomic Number
they're called isotopes.
1. An element contain only specific atoms of this element and no other atoms. 2. Compounds as calcium aluminates contain both aluminum and calcium.
same number of each element
Because it has the same kind of atoms through and through. Calcium doesn't contain anything else than calcium. And anything that consists of only one kind of atoms is an element.
Isotopes are species of atoms having same atomic no. but different atomic masses. So an isotope has either lesser or more neutrons than the usual atom of the element ( often called the most abundant isotope).
An isotope is an atom of an element. Isotopes are atoms of the same element that have different numbers of neutrons. However, all atoms of the same element have the same number of protons.
yes. but only for a given isotope
They would have to be atoms of the same element, and the same isotope of that element.
An isotope of an element.
No. If two atoms are the same then they are of the same element. The type of atoms is determioned by the number of protons in the nucleus. A chlorine atom has 17 protons, a calcium atom has 20.
well, they are the same thing unless there are now a isotope
Two atoms of same element (for a given isotope) are identical and hence have the same atomic radius.
