Question

the elements x and y havee the following configuration x=2,8,1 y=2,8,7 what is the nature of the bond between x and y​

Answer 1

Answer:

Ionic bond

Explanation:

There are mainly 2 types of bonds formed. They are:

• Ionic bonds
• Covalent bonds

★ Ionic bonds are formed due to the exchange of electrons between metals and non metals.

Ex: MgCl₂, NaOH, MgSO₄

★ Covalent bonds are formed due to the sharing of electrons between 2 non metals

Ex: CO₂, HCl, CH₄

In this particular question:

• x has 1 electron extra in its outermost shell. It donates that electron and so it is a metal.
• y has 7 Electrons in its outermost shell. It can accept 1 electron rather than donating 7 electrons. So, y is a non-metal.

Since the exchange of electrons is happening between metals and non-metals, it is an ionic bond.
