Question 1

What is a covalent bond?

Answer 1

Two at share electrons is called equivalent bond

Question 2

How are covalent bonds different than ionic bonds

Answer 2

Ionic bonds form which form between metals

Question 3

What is a double bond

Answer 3

When two pairs of electrons are shared

Question 4

What are molecular compounds?

Answer 4

They consist of molecules having covalent bonded atoms

Question 5

What does polar mean?

Answer 5

A covalent bond in which electrons are shared uniquely is polar

Question 6

What does nonpolar mean?

Answer 6

Nonpolar and F2 the two chlorine atoms pull equally on the shared electrons

Question 7

Why is water polar? Explain.

Answer 7

The shape of the molecule leaves the two hydrogen atoms at one end and the oxygen atom at the other, creating an uneven distribution of charge.

Question 8

Is CO₂ polar or nonpolar? Why?

Answer 8

CO₂ is nonpolar because the valence electrons are shared equally.

Question 9

Why don’t oil and water mix? Explain.

Answer 9

Oil is nonpolar and non-polar compounds do not dissolve well in water, polar water. Molecules are attracted more strongly to each other than molecules of oil water stays with water oil stays with oil

Question 10

How are ionic bonds different from covalent bonds?

Answer 10

Ionic bonds form between metals and nonmetals, while covalent bonds form between two or more nonmetals.

Question 11

Adams Bond, because they become more blank when they have blank, outer blank, donating, blank, or sharing blank, allows them to achieve blank, the blank rule eight electrons in the blank shell

Answer 11

Stable full shells, receiving electrons stability octet outer
