Explanation:

When a chemical bond is formed by sharing of electrons then it is known as a covalent bond.

A covalent bond is always formed between two non-metals.

For example, atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.

As a result, it needs one more electron to complete its octet. So, when it chemically combines with another chlorine atom then there will occur sharing of electrons.

Hence, $Cl_{2}$ is formed which is a covalent compound.

On the other hand, when a chemical bond is formed by transfer of electrons from one atom to another then it is known as an ionic bond. An ionic bond is always formed between a metal and a non-metal.

For example, LiCl is an ionic compound.

Thus, we can conclude that in a chlorine gas covalent bonding is present when two chlorine atoms share an electron.

A chemist prepares a solution of sodium chloride by measuring out 25.4 grams of sodium chloride into a 100. mL volumetric flask

mr_godi [17]

Answer:

The concentration in mol/L = 4.342 mol/L

Explanation:

Given that :

mass of sodium chloride = 25.4 grams

Volume of the volumetric flask = 100 mL

We all know that the molar mass of sodium chloride NaCl = 58.5 g/mol

and number of moles = mass/molar mass

The number of moles of sodium chloride = 25.4 g/58.5 g/mol

The number of moles of sodium chloride = 0.434188 mol

The concentration in mol/L = number of mol/ volume of the solution

The concentration in mol/L = 0.434188 mol/ 100 × 10⁻³ L

The concentration in mol/L = 4.34188 mol/L

The concentration in mol/L = 4.342 mol/L

How many valence electrons do the halogens possess? group of answer choices

jok3333 [9.3K]

The valence electron does the halogens possess are 7

Valence electrons are found in the outermost energy level of an atom
They are involved in the formation of chemical bonding with other atoms.
The halogens elements are found in group 17 on the periodic table
The halogens include fluorine, chlorine, bromine, iodine and astatine.
They have seven valence electrons, so they are extremely reactive as they only need one more to fill their outer shell.
By octet rule we can say that the electron with 8 outer most shell is full and stable.

Hence the halogens posses 7 valence electron
