Question

An element X has mass no. 35 and atomic No. 17. Which is the correct statement 2 points 17 protons,18 electrons 17 protons,18 neutrons 18 protons,17 electrons 18 protons,17 neutrons

Answer 1

Answer:

correct answer is 17 electrons and 17 protons and 18 neutrons

Answer 2

The element is chlorine

Mass no. = 35

Atomic number = 17

Atomic number = no. of protons

And no. of protons = no. of electrons

So, 17 electrons and 17 protons are present each

No. of neutrons = Mass no - atomic no = 35 - 17 = 18 neutrons

So, the correct option is: 17 protons and 17 neutrons
