Answer:
Protons and Neutrons
Explanation:
The sum of number of protons and the number of neutrons is equal to the mass of an element. Mathematically, it can be given as :
M = P + N
Also, the atomic mass can be calculated by the sum of the element's isotopes as isotopes have slightly different mass numbers.
Hence, protons and neutrons add together to determine the atomic mass.
An atom consists of three subatomic particles.
In the middle of atom it consists of nucleus which have two subatomic particles. They are protons and neutrons.
And there is a subatomic particle that is found orbiting around the nucleus in an atom, name of that subatomic particle is electron.
Hope this helps!
Chemical property because heat is not electrical.
The number of neutrons in an atom is the number of particles present in its nucleus.
The atomic number is the number of protons whereas the mass number is the number of protons and number of neutrons together
This implies that the number of neutrons is the atom's mass number
Answer:
613 mg
Explanation:
Number of fargday's 
Here, I = 9.20 A
t = 10.5 min
= 10.5 x 60 seconds
So, 
= 0.0208 F
Here, 2e, 2F
2F = 1 mol of Ni
1 mol = 59 gm of Ni
0.0104 mol = 59 x0.0104 gm Ni
= 0.613 gm Ni
= (0.613 x 1000 ) mg of Ni
= 613 mg of Ni
