Question

plzz help me....urgent

Answer 1

here is your answer dude ✌✌✌

formula used =

number of protons + number of neutrons

(no of eletrons) = mass number

mass number of He = 4
number of protons in He = 2

using the formula = number of protons + number of neutrons = mass number

number of neurons = mass number - no of protons

no of neutrons = 4 - 2 = 2

therefore no of neutrons in Helium atom = 2

Hope this helps u dude nd be brainlist ✌✌✌
