Question

Q2. Differentiate between the following pairs: (One point of difference)
a. Duplet rule and Octet rule
b. Nucleus and Nucleons
c. Electrovalent bond and Covalent bond

Answer 1

Answer:

2a.

The key difference between octet and duplet is that octet is an atom or an ion having a maximum of eight electrons in the outermost shell while duplet is an atom having the maximum of two electrons in the outermost shell.

b. Nucleus Nucleolus

Bound by the nuclear envelope. It has no limiting membrane.

c. The key difference between electrovalent and covalent bond is that electrovalent bond occurs by transferring electrons from one atom to another whereas covalent bond occurs as a result of sharing valence electrons between atoms. An ionic bond is also called an electrovalent bond.

Hope this may helpful my friend.
