Question

how to find how many protons and electrons are there in an atom​

Answer 1

Answer:

The number of protons in the nucleus of the atom is equal to the atomic number (Z).

The number of electrons in a neutral atom is equal to the number of protons.

The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Answer 2

Answer:

the atomic number is equal to the number of protons. and if there is no charge mentioned then the number of electrons are equal to the number of protons. it it is containing negative charge then add that charge number to the number of protons and here you get number of electrons in an anion. if there is positive charge just subtract that charge number from the number of protons and you will get number of electrons in a cation.

example:

Na neutral atom has atomic number = 11

so number of protons are 11 and same the number of electrons also.

Na+ has 11 protons

and number of electrons = 11-1 = 10.

similarly, for F it is 9 protons and electrons.

for F- it is 9 protons but 9+1=10 electrons.
