In a molecule of fluorine, the two shared electrons give each fluorine atom how many electron(s) in the outer energy level
timofeeve [1]

Answer:

8 electrons

Explanation:

As per the <u>octet rule</u>, the atoms possess a tendency to bond in a manner that every atom must have at least eight(8) electrons in its outermost/valence shell. It can be done either by sharing, gaining, or losing electrons from one atom to another. According to this rule, flourine would have 8 electrons in its outer shell after two shared electrons are given to it.

There are three ways in which heat be transferred - conduction, convection, and radiation. Which types of thermal transfer invol
lesantik [10]

Answer:

Convection.

Explanation:

Let us define each of the type of thermal transfer first:

- radiation is heat transfer that does not include contact between the objects. It's mediated by infra-red radiation, waves from the invisible radiation spectrum.

- conduction is heat transfer which is mediated through direct contact between objects (holding a hot cup of tea, for example)

- convection is a heat transfer found in gases and liquids. Due to different temperatures in two parts of liquid, there will also be a different density ( hotter parts have lower density). Lower density parts will start moving upwards while higher density parts, due to gravity, will move downward. As they move, they will gain or receive heat, which will cause new temperature differences and the moving will restart.
