Two elements x and y have atomic number 12 and 15 respectively write the electronic configuration of this elements what type of bond is formed if these two elements
Answers
The element x has atomic number 12. So the electronic configuration of x will be - 2.8.2
Again the element y has atomic number 15. So the electronic configuration of y will be- 2.8.5
The element x is Magnesium and the element y is Phosphorus.
Hope it helps...
Answer: a)
b)
c) ionic bond
Explanation:
An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and forms a positively charged ion called as cation. The element which accepts the electrons is known as electronegative element and forms a negatively charged ion called as anion.
Electronic configuration for element x with atomic number 12 is magnesium
Electronic configuration of element y with atomic number 15 is phosphorous
x atom will loose two electrons to gain noble gas configuration and form cation with +2 charge.
y atom will gain three electrons to gain noble gas configuration and form anion with -3 charge.
Thus and combine together and exchange their valencies to form neutral ionic compound
