Question

how many protons,electrons and neutrons in 9fe19​

Answer 1

Answer:

no. of protons = no. of electrons = atomic number = 9

no. of neutrons = mass no. - atomic no.

=  19 - 9

= 10

protons = 9

electrons = 9

neutrons = 10

POINTS TO NOTE :-

1. The atomic number or proton number (symbol Z) of a chemical element is the number of protons
2. The mass number is the sum of protons and neutrons found in the nucleus of every atom of that element.
3. The atomic number uniquely identifies a chemical element.
4. The atomic number is identical to the charge number of the nucleus.
5. In an uncharged atom, the atomic number is also equal to the number of electrons.
