Help please manganese atom has 30 neutrons and atomic number 25
determine the electron cloud charge of manganese

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

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
