Atomic mass is the number that you get when the protons and neutrons in the nucleus are added together atomic number is the number of protons in the nucleus
Answer:
electron cloud charge of manganese=-5
Explanation:
atomic number=number of elecron +neutron number
DATA
Neutron NO.=30
atomic NO.=25
e=?
A=e+n
25=e+30
e=25-30
e= -5
Potassium carbonate<span> (K</span>2CO3<span>) is a white salt, </span>soluble in water<span> (</span>insoluble<span> in ethanol) which forms a strongly alkaline solution. </span>
Atomic no = no of electrons present in atom
and atomic mass = no of protons + no of neutrons
It should be D, cells are parts, tissue is part and organ is part of a system.
