Which pair of elements will form a covalent bond?

Chemistry
2 answers:
Dominik [7]3 years ago
7 0

Answer: Option (A) is the correct answer.

Explanation:

A covalent bond is formed when there occurs sharing of electrons between atoms.

For example, in hydrogen atom there is one electron in its orbit and in a chlorine atom there is 7 valence electron. So, in order to attain stability both hydrogen and chlorine share electrons when they come close to each other.

Whereas except hydrogen and chlorine rest of the given atoms will form ionic bond, that is, bond formed by transfer of electrons.

Thus, we can conclude that a pair of hydrogen and chlorine will form a covalent bond.

\boxed{{\text{A}}{\text{. hydrogen and chlorine}}} will form a covalent bond.

Further Explanation:

The bond that is formed by the mutual sharing of electrons between the bonded atoms is called a covalent bond. It is also known as a molecular bond. Covalent compounds are those compounds which are formed by the electron sharing between two or more non-metals.

Following are some of the properties of covalent compounds:  

1. These are brittle solids.

2. Low melting and boiling points.

3. Poor conductors of heat and electricity.

4. Low enthalpy of fusion.

Boron trichloride \left( {{\text{BC}}{{\text{l}}_3}} \right), silicon dioxide   \left( {{\text{Si}}{{\text{O}}_2}} \right), and xenon hexafluoride  \left( {{\text{Xe}}{{\text{F}}_{\text{6}}}} \right) are some examples of covalent compounds.

Ionic bond results from the interaction of a metal with a non-metal. Metal atom loses electron by virtue of its low ionization energy and forms a cation. This electron is gained by the non-metal atom and an anion is formed.

Following are some of the properties of ionic compounds:  

1. These are hard solids.

2. High melting and boiling points.

3. Good conductors of heat and electricity.

4. High enthalpy of fusion.

Sodium chloride (NaCl), potassium chloride (KCl) and barium oxide (BaO) are some of the examples of ionic compounds.

(A) Both hydrogen and chlorine are non-metals and the bond formed between two non-metals is a covalent bond. So hydrogen and chlorine will form covalent bonds with each other and the resulting compound HCl will be covalent compound.

(B) Sodium is metal while chlorine is a non-metal. So ionic bond will be formed by their interaction and the compound NaCl will be an ionic compound.

(C) Copper is metal while bromine is a non-metal. So ionic bond will be formed by their interaction and the compound CuBr will be an ionic compound.

(D)  Zinc is metal while bromine is a non-metal. So ionic bond will be formed by their interaction and the compound ZnBr will be an ionic compound.

So covalent bond will only be formed by hydrogen and chlorine.

When studying atoms, scientists can ignore the
vekshin1

When studying atoms, scientists can ignore <u>the Gravitational</u> force between charged particles that make up  the atoms because it is many millions of times smaller than other forces in the atom.

Explanation:

Scientists can ignore the gravitational force because the gravitational force is considered to be negligible as compared to the other forces due to its smaller value.We all know that the gravitational force is directly proportional to the mass of an object which  result in  a small force value.When the value of this small force is compared to the value of the electrical force between protons and electrons in atoms the we can say that the electrical force is million times stronger than the gravitational force

Thus we can say that scientists can ignore <u>the Gravitational</u> force between charged particles that make up  the atoms because it is many millions of times smaller than other forces in the atom.
