Question

An element (M) has 25% more protons than 18O (18 mass number) and equal no. of neutrons . Caluculate no.of nuetron - no. of electrons in M+2.
Please dont answer if you dont know .

Answer 1

$5225M2 \: + \: , \: Z \: = \: 25 \\ =p,e=25−2=23.2552M2+, \\ Z=25=p,e \\ =25-2=23</p><p>A=52A=52</p><p>n=A−Z=52−25=27n=A-Z=52-25=27.$

Answer 2

Answer:

Atomic number and mass number of an element M are 25 and 52 respectively. The number of electrons, protons and neutrons in M+2 ion are respectively.  n=A-Z=52-25=27.
