my ans is wrong . but Si and Ge in same grup meant they wud form same oxides and their reaction with any thing wud be of same intensity.

Si grp 4
prid 3

germanium 4 grup

both are in the same group and would have same number of shells.

Hi Sharon,

Good to see you participating.

Confucius once said: “Hear and you forget, See and you rmbr, but only when you Do you tend to understand”

Question 1: You are absolutely correct. Well Done!

Question 2: Yes, both in same group thus same valency and number of valence electrons.Can you tell me more about the physical and chemical similarity for both Si and Ge? Examiners will be looking for that.

Hear from you. Leave your comments directly below.

Hi Kwee,

Point 1: You are absolutely correct. Well done!

Point 2: Yes both have 4 valence electrons. Can you tell me more about the physical and chemical similarity for both Si and Ge? Examiners will be looking for that.
