Question

1. from the picture below, what are true options (select two) for the isotopes of an element? atomic symbol abbreviation used to represent atom in chemical formulas mass number number of protons and neutrons in atom atomic number number of protons in atom the isotopes have same number of protons but different number of neutrons. the isotopes have same number of protons and neutrons. the isotopes have same \z\ but different \a\. the isotopes have same \z\ and \a\.

Explanation:

Isotopes are atoms of the same element. They have the same number of protons (atomic number, Z) but different numbers of neutrons, which leads to different mass numbers (A).

Answer:

The isotopes have same number of Protons and neutrons.
The isotopes have same "Z" but different "A"
