Explain in words or using your diagrams how beryllium atoms would react with fluorine atoms.

Marysya12 [62]

Explanation:

To delineate the the nature of the bonds that would be formed between the two elements, let us first write the electronic configuration of the two species;

Be = 2, 2

F = 2, 7

Beryllium is a metal with two valence electrons whereas fluorine is a halogen with seven valence electrons.

When Be loses two electrons it becomes isoelectronic with He;

Be → Be²⁺ + 2e⁻

Also, when fluorine gains an electron, it becomes isoelectronic with Ne;

F + e⁻ → F⁻

This loss and gain of electrons between the two elements creates an electrostatic attraction them and they enter into an electrovalent bond.

Hence;

Be²⁺ + 2F⁻ → BeF₂

The graph shows the solubility of several different salts in water, across a range of temperatures. According to the

sladkih [1.3K]

Answer:

Sodium chloride

See the graph attached

Explanation:

The attached graph with a green and a red arrow facilitates the understanding of this explanation.

To read the solubility on the graph, you can start with the temperature, on the x-axis.

The red vertical arrow shows how, departing from the 40ºC temperature on the x-axis, you intersect the solutibility curve of sodium chloride at a height (y-axis) corresponding to 60 g/100cm³ of water (follow the green horizontal arrow).

Hence, sodium chloride is the salt that can dissolve at a concentration of about 60g/100cm³ of water at 40ºC.
