Question

if no. of electron in X raize to power -2 is 20.and mass no. is 34. then calculate no of proton ,electron, neutron for X raize to power +3 ion.​

Answer 1

Answer:

X^-2 no of electrons = 20

Protons = 18

Neutrons =mass no -atomic no

34-18 =16 neutrons

Explanation:

X+3 = loss or gain only in terms of electrons so proton and neutron same as inX-2 proton =18 neutron 16 electron X =18elecryron

X+3 means loss of 3 electrons so 15 electron
