Question

The atomic number of an element ‘X’ is 11 and the atomic number of ‘Y’ is 17.

Then the type of bond formed between these two elements

A. hydrogen bond
B. covalent bond

C. ionic bond
D. metallic bond​

Answer 1

The type of bond formed between these two elements Ionic bond.

Explanation:

1. The element 'X' with the atomic number 11 is Sodium.
2. The element 'Y' with the atomic number 17 is Chlorine.
3. The type of bond formed between Sodium and Chlorine is an ionic bond.
4. Ionic bond is also called an electrovalent bond.
5. This type of bond shows the linkage between two elements attracted by electrostatic force.
6. They are formed by the complete transfer of one or more electrons in between the elements.
7. The ionic bond is formed by the loss of electrons from Sodium atom and gain of electrons to Chlorine atom.

Answer 2

Answer:

Option C is the correct answer that is the bond will be ionic bond.

Explanation:

• The element which has atomic No.11 its electronic configuration is (2,8,1) it has one electron in its outermost shell which it wants to donate to attain stability. For Eg - sodium Na
• The element having 17 atomic no.  having electronic configuration (2,8,7) is a halogen it requires one electron more to achieve its stability hence it will attract or accept a extra electron in its outer shell. Like Chlorine Cl
• These two element fulfill each others requirement to attain stable configuration hence due these exchange of ions they are held by electrostatic force and they form strong Ionic Bond.
