A chemical bond is formed between magnesium and chlorine. Describe the process and identify the nature of the chemical bond.

IRINA_888 [86]

Answer:

The answer to your question is: b

Explanation:

a. Magnesium shares an electron somewhat unevenly from its 3s orbital with the 3p orbital of chlorine producing a mildly polar covalent bond. This option is wrong because Mg does not share electrons it loses electrons.

b. Magnesium loses and electron from the 3s and gives it up to the 3p of chlorine producing an ionic bond. This option is correct, Mg loses one electron and Cl receives it, the bond formed between Mg and Cl is ionic.

c. Magnesium does not react chemically with chlorine because magnesium gives up electrons, but chlorine only shares electrons. This answer is wrong, Mg and Cl react and produce MgCl₂.

d. Magnesium shares an electron from the 3s orbital with the 3p orbital of chlorine producing a covalent bond. Mg does not share electrons and is not able to produce covalent bonds.

In a neutral atom, the number of protons is always equal to what other part of the atom?

Licemer1 [7]

Answer:

b. The number of electrons

Explanation:

A "neutral atom" has a neutral charge. This means that its charge is equal to zero. In order for the charges to cancel out each other, the atom's positive charge should be equal to the negative charge. These being said, the number of electrons (negatively-charged) is then equal to the number of protons (positively-charged). Those atoms which are not neutral are called "ions." This means that they either have more or less electrons than the protons.
