Question

two elements are represented as 35x17 and 24y12 !
i) WHICH Of these elements gain electrons and loose electrons .
ii)what is the number of electrons an atom loose gains or share called.
iii)write electronic configuration of x and y
​

Answer 1

Explanation:

cl ^- --- 1e^- + +cl

Mg +1e^- + Mg^+

2Mg +2Cl 2-----2MgCl 2

when an atom lose electron it is called cation

when an atom gain electron i is called anion

sharing of electron is covalent bond

x= 1 s^2 2s^2 2p6 3s2 3p5

y= 1s22s2sp63s2
