Answer:
Electron = 10
Proton = 10
Neutrons = 11
Explanation:
if you want to calculate the number of neutrons and element simply , just subtract number of The number of electrons in a neutral atom is equal to the number of protons. or the atomic number fom the mass number n atomic number of an element is equal o the number of electrons present
Atomic no = no of proton present or
Mass number = proton + neutrons
21 = protons +11
protons = 10
The number of electrons in a neutral atom is equal to the number of protons.
It would be a mixture or atom
