Question

1) For the dots picture shown the most likely elementare X=.....and Y =.....

with solution plz

Answer 1

X is carbon and Y is Fluorine i.e. D option.

Reason is
Carbon can make maximum 4 bonds as its valency is 4.
And Y element has total 7 electrons in valence shell and out of that 1 electron has gone for bonding. Hence 6 electrons are left in valence.

Therefore Y is Flourine as it has 7 electrons in valence shell.


Hope it helps!!!

Answer 2

hi ✌️

option D is your answer...


solution:-
========

we know that , In octet rule kossel and Lewis observed that atoms of inert gases contained 8 electrons in the valence shell .This ,atoms having less than 8 electrons are reactive and capable of chemical combination.

so according to octet rule ,

1)carbon has atomic number is 6

outer must orbital contain 4 electron

so carbon required only 4 electron to octet

☑️fluorine has atomic number 9

outer must orbital contain 7 electron .

it required only 1 electron to octet

so fluorine shared their electrons with carbon because carbon needs 4 electrons.

so. here x is carbon and y is fluorine .

it's ur answer ☑️

but in other options their will not possible of octet rule


hope it will help you ☺️
