Answer:
1:both B&D are properties of solid
2:conductivity as other factors like lustre needs continuous supply of photons of light
3:D due to it's covalency
1. Brittle
2. Conductivity
3. CF₄
Further explanation
The formation of electron configurations such as noble gases can be done by sharing electrons with covalent bonds or hand over electrons with ionic bonds
1. A solid with the type of bonding represented in the picture(attached) describes the ionic bond on a solid / crystal that is brittle because of the influence of pressure and produces repulsion between similar ions
2. The metal ions seem to be floating in a sea of electrons, so In ionic bonds, ions can move so that they can conduct electricity and are conductors, so they have conductivity values
3. For ionic compounds consisting of cations (ions +) and anions (ions -)
For metal and non-metal compounds like C and F :
Metal: cation, positively charged (C⁴⁺)
Nonmetal: negative anion (F⁻)
The anion cation's charge is crossed become : CF₄
