Question

calculate the number of electron , proton and newton in 35/17 Cl​

Answer 1

Answer:

I learnt this but this question doesn’t make sense but I can teach you something.

ATOMIC NUMBER: is the number of protons an atom contains

MASS NUMBER: is the amount of protons PLUS the amount of neutrons an atom contains. This represents the mass of the nucleus

The atom in the diagram above contains 3 protons therefore it has an atomic number of 3

It also contains 4 neutrons therefore its mass number is 7 (4 neutrons + 3 protons)

while the number of neutrons and protons may not always be the same, the number of protons is always equal to the number of electrons.

# of protons = # of electrons = atomic number

the number of neutrons can be calculated by subtracting the atomic number from the mass number

# of neutrons = mass number – atomic number
