What is necessary for a metallic bond to form? the atoms should be in close proximity. the atoms should be far apart. the electrons must be attracted to each other. the nuclei must contain neutrons.

The electrons must be attracted to each other.

Answer is: The atoms should be in close proximity.

1. Metallic bond is a type of chemical bond.  

2. Metallic bond is formed between electrons and positively charged metal ions.  

3. Metallic radius is defined as one-half of the distance between the two adjacent metal ions.  

4. Metallic bond increace electrical and thermal conductivity.  

5. Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
