Answer:
Low melting point
Explanation:
Transition metals have the following properties:
Conductivity (Electrical and Thermal)
Malleability (You can hit it with a hammer to mold it)
High melting point
The molar mass is 242 g/mol (<span>241.8597 g/mol). There is a very good online service to calculate molar masses:

Isotopes are basically from the same element. In terms of subatomic particles of the element, the isotopes will then basically have the same number of protons. The electrons also have to be same in number given that the elements are in neutral charges.
We are then left with neutrons, which is one of the subatomic particles residing in the nucleus of an atom.
Thus, the answer is NEUTRONS.
Answer:
The answer is A. Polar covalent; negatively
Explanation:
Hydrogen bonds form between molecules containing polar covalent bond the hydrogen bond is been a hydrogen atom of one molecule and a partially negative charged atom of another.
Example 
(water):- It contain a slight positive charge on one side and a slight negative charge on the other.
D. Yep, D is the answer, alright.
