Different forms of the same element that have different numbers of neutrons in the nucleus. This means it has a different mass number, the same charge and the same atomic number.

(Name of Element)-(Mass Number). Eg. Carbon with two more neutrons is C-14

Relative Atomic Mass = Sum of (Isotope abundance x Isotope Mass Number) / (Sum of isotope abundances)

What is the formula for relative atomic mass

What is the name of a compound consisting of a metal and a non metal

What is the name of a compound consisting of two non metals

The metal will give electrons to the non metal which makes the metal a positive ion and the non metal a negative ion. (The opposite charges are strongly attracted to each other)

A substance consisting of two or more different elements that have been chemically combined

The two non metals share electrons to create molecules

ifferent forms of the same element that have different numbers of electrons in the nucleus. This means it has the same mass number, different charge and the same atomic number.

(Name of Element)^(Total Charge) Eg. Carbon with 2 less electrons is C^2+
