What type of bond is formed when electrons are transferred from one atom to another?

• Metallic bond

• Covalent bond

• Ionic bond

• Hydrogen bond

Answer explanation

Ionic bond is formed when electrons are transferred from one atom to another.

In an ionic bond, what happens to the electrons?

• shared

• lost

• transferred

• duplicated

Answer explanation

In an ionic bond, electrons are transferred from one atom to another, leading to the formation of positively and negatively charged ions.

What type of elements typically form ionic bonds?

• Metal and metal elements

• Non-metal and non-metal elements

• Noble gas elements

• Metal and non-metal elements

Answer explanation

Ionic bonds are typically formed between metal and non-metal elements, where the metal atom loses electrons to become a cation, and the non-metal atom gains electrons to become an anion, resulting in an electrostatic attraction between the oppositely charged ions.

How are electrons shared in a covalent bond?

• Electrons are shared with three atoms

• Electrons are shared between an atom and a molecule

• Electrons are only present in one atom

• Electrons are shared between two atoms.

Answer explanation

In a covalent bond, electrons are shared between two atoms.

What is the charge of an ion that has gained one electron?

• 2

• -1

• +1

• 0

Answer explanation

An ion that has gained one electron will have a negative charge, specifically -1 charge.

Which of the following compounds is ionic?

• NaCl (Sodium Chloride)

• CH4 (Methane)

• CO2 (Carbon Dioxide)

• H2O (Water)

Answer explanation

NaCl (Sodium Chloride) is the only ionic compound among the options provided.

What is the name of the bond formed between two nonmetals sharing electrons?

• Ionic bond

• Covalent bond

• Metallic bond

• Hydrogen bond

Answer explanation

The correct bond formed between two nonmetals sharing electrons is a Covalent bond, where electrons are shared to achieve stability.

What is the formula for sodium chloride?

• C6H12O6

• NaCl

• CO2

• H2O

Answer explanation

The formula for sodium chloride is NaCl, which represents one sodium atom (Na) and one chlorine atom (Cl) bonded together.

Which of the following is a property of ionic compounds?

• Always Liquid

• Lower Melting Points

• Poor Electricity Conductors

• Higher Melting Points

Answer explanation

Ionic compounds have higher melting points due to strong electrostatic forces between ions.

Which type of bond is characterized by the sharing of electrons between atoms?

• Hydrogen bond

• Ionic bond

• Covalent bond

• Metallic bond

Answer explanation

A covalent bond is characterized by the sharing of electrons between atoms, making it the correct choice in this scenario.
