Which sample contains the same number of atoms as a gram atomic mass of he?
A gram atomic mass of helium (He) contains the same number of atoms as 1 mole of helium. Since 1 mole of any substance contains approximately 6.022 x 10^23 atoms, a sample of helium with a gram atomic mass would contain that same number of atoms.
Can All carbon atoms have the same atomic number?
Yes, all carbon atoms have the same atomic number, and that is 6.
How did Mendeleev arrange atoms in the periodic?
Atomic Mass
What does Bohrs diagram represent?
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
What does it mean if two atoms are isotopes?
Two atoms are isotopes if they have the same number of protons but different numbers of neutrons in their atomic nuclei. This results in atoms of the same element having different atomic masses.

How do the sizes of atoms vary within a group (family)and explain why?
The atomic radius increase down in a group; the cause is the lower attraction from the nucleus atoms with increased bigger atomic mass.
