What types of elements typically combine to form covalent compounds?metals
nonmetals and metals
metalloids and metals
nonmetals

Answers

Answer:

Nonmetals  typically combine to form covalent compounds.

Explanation:

The octet rule states that the atoms of the elements bond each other in the attempt to complete their valence layer with eight electrons. That is to say, the atoms will tend to yield or share electrons to complete eight electrons in the valence layer.

In other words, the objective is to have the closest noble gas electronic configuration, thus having the last complete electron layer and acquiring stability.

The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements. These elements have many electrons at their outermost level (valence electrons) and tend to gain electrons in order to comply with the octet rule mentioned and be stable. The shared electron pair is common to the two atoms and holds them together.

Then, nonmetals  typically combine to form covalent compounds.

Answer: ionic bonds can form between nonmetals and metals, while covalent bonds form when electrons are shared between two nonmetals.

Explanation:

where is the amount of water vapor in the air likely to be highest, above a desert or a tropical rain forest?

Answers

Desert due to the high temperatures, therefore any water can evaporate and will be in the air as water vapour. In a rainforest it is usually cold so it is less likely that there will be water vapour as there is not much water evaporating.
