Answer:
B is the answer
Explanation:
I took the test
Explanation:
Ionic compounds are the compounds formed by transfer of electrons between its atoms. Atoms of ionic compounds have opposite charge and that is why these atoms are held together by strong forces of attraction.
As a result, melting point of ionic compounds is high.
Whereas molecular solids are attached by weak Vander waal forces, that is, melting point of molecular solids is low.
Thus, we can conclude that compared to the melting points of ionic compounds, the melting point of molecular solids tend to be low.
Cubic metre is the metric unit for measuring volume. The cubic centimetre has a particular nomenclature called a millilitre.
The 3-dimensional space that is occupied by matter or surrounded by a surface is measured in volume, which is expressed in cubic units. A derived unit called the cubic metre serves as the SI unit of volume.
A unique designation for the cubic decimeter is the litre. To reduce the chance of confusion between the lowercase letter "ell" (l) and the number one (1), the symbol for the litre is an uppercase letter "ell". The litre cannot be represented by the script letter l (l).

The correct answer fro above statement is:
Some elements in the atmosphere start the body and are consistent when they are dropped. Others are diminishing. Degradation stocks may be more lethal or less virulent than the first chemical. Other chemicals are deposited momentarily in the organs and are discharged shortly after. After a while, most chemicals and degradation stocks are ordered of as body waste, in the stool, urine, sweat and breathed air.

Answer:
Explanation:
The electronic configuration of chlorine can be written as 2, 8, 7. ... Therefore, valence electron in chlorine is 7 and it needs to gain 1 electron from the outermost orbit to attain octet. Hence, the valency of chlorine is 1.
