Helium (He) has an Atomic Number Z=2 and an atomic mass of 4.002602. It has eight isotopes. One of them is 6He (atomic mass number 6).
a) How many protons are in a neutral 6He atom?
b) How many nucleons (that is protons and neutrons) are in a neutral 6He atom?
c) How many electrons are in a neutral 6He atom?
d) How many neutrons are in a neutral 6He atom?
a) Number of protons are in a neutral 6He atom is = 2
b) Number of nucleons (that is protons and neutrons) are in a neutral 6He atom is = 6
c) Number of electrons are in a neutral 6He atom is 2
d) Number of neutrons are in a neutral 6He atom is = 6-2 = 4
