Question

electronic configuration if X=2,Y=2,6 and Z=2,8,2 .
1)Write the chemical formula of compound formed by Y and Z.
2)Write valency of X,Y,Z.
3)Which element easily loses electron.

tell fast! good morning. ☺

Answer 1

1)z and y have both of valency 2
therefore;z2Y2
=zy

or

CaO

2)valency
X=0
Y=2
Z=2

3)Z will easily lose electron
because he with e 2 is noble gas and do not lose e

Answer 2

1)zy

both have 2 valency and z loose 2 electron to stable and y gain 2 electron to electron to stable

2)0,2,2

in both three atom the number of loose and gain electron are called valency

X is stable as it complete his duplate so no loose or gain electron

y and z explain above

3)z
