Answer:
On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

Answer:
b) Silicon and oxygen
Explanation:
A compound is a pure substance that contains two or more atoms chemically joined together. Sand is regarded as a 'compound' because it is made up of two or more atoms that are chemically bonded to one another.
Sand is said to predominantly contain silica, which has a chemical formula of SiO2. Hence, sand can be said to be a compound containing one atom of silicon (Si) and two atoms of oxygen (O2).
C.) a substance with a low ability to conduct energy
Explanation:
The statement that best defines insulators is that it is a substance that has low ability to conduct energy.
Insulators resist the movement of mostly electrical and thermal energy.
They have unique properties that makes them so.
- Insulators are substances that do not conduct heat and electricity.
- Both their solid and molten form lacks the capability of electrical and thermal conduction.
- Some substances can only conduct when molten or liquid.
- Conductors are materials that allows for the passage of electrical and heat energy.
- Most conductors are usually salts, ionic compounds and metals.
- Non-conductors like insulators are usually plastics and woods.
