Question

Atomic numbers of elements A, B, C, D, E, F are 8, 7.11
12,13 and 9 respectively. State the type of ions they form​

Answer 1

A -

Atomic no. = 8

Valence electrons = 6

Forms negative ions because it gains 2 electrons

-------------

B -

Atomic no. = 7

Valency electrons = 5

Forms negative ions as it gains 3 electrons

--------------

C -

Atomic no. = 11

Valence electrons = 1

Forms a positive ion as it looses 1 electron

---------------

D -

Atomic no. = 12

Valence electrons = 2

It forms positve ions as it looses 2 electrons

----------------

E -

Atomic no. = 13

Valence electrons = 3

Forms positive ions because it looses 3 electrons to form an octet.

-----------------

F -

Atomic no. = 9

Valence eletrons = 7

It forms a negative ion as it gains 1 electron to form an octet

__________

Answer 2

Answer:

A forms negative ions

B forms negative ions

C forms positive ions

D forms positive ions

E forms positive ions

F forms negative ions
