MULTIPLE CHOICE QUESTION

2 mins • 1 pt

Predict the bond that is formed between Phosophorus and Chlorine?

Ionic

Covalent

Metallic

H-bond

Answer explanation

Phosphorus and chlorine form a covalent bond because they share electrons to achieve stability. Both elements are nonmetals, which typically engage in covalent bonding rather than ionic or metallic bonding.

Which of the pair of elements form an ionic bond?

Magnesium and Oxygen

Magnesium and Sodium

Iron and Zinc

Nitrogen and Hydrogen

Answer explanation

Magnesium and Oxygen form an ionic bond because magnesium loses two electrons to become Mg²⁺, while oxygen gains two electrons to become O²⁻. This transfer of electrons creates a strong electrostatic attraction between the ions.

How many valence electrons are shown in the diagram?

16

7

6

2

Answer explanation

The diagram shows 6 valence electrons, which are typically represented as dots around the element symbol. This corresponds to the correct answer choice of 6, indicating the number of outer shell electrons.

TRUE OR FALSE: Ionic compounds have high boiling points because they consist of a strong ionic bond.

TRUE

FALSE

Answer explanation

TRUE: Ionic compounds have high boiling points due to the strong ionic bonds between their charged ions. These bonds require a significant amount of energy to break, resulting in higher boiling points.

How do covalent bonds form?

Donating & receiving valence e- between atoms.

Opposite slight charges attract each other between compounds.

Scientists are still not sure how they form.

Sharing valence e- between atoms.

Answer explanation

Covalent bonds form when atoms share valence electrons. This sharing allows each atom to achieve a more stable electron configuration, which is the basis for the formation of molecules.

What is the basis of a metallic bond?

the attraction of neutral metal atoms.

the attraction between protons and neutrons.

the attraction between positive metal ions and interlocking electrons.

the attraction between positive metal ions and free floating electrons.

Answer explanation

A metallic bond is characterized by the attraction between positive metal ions and free floating electrons, which allows for conductivity and malleability, distinguishing it from other types of bonds.

The ability of a material to be shaped in all directions without cracking or breaking.

hardness

ductility

malleability

conductivity

Answer explanation

Malleability is the ability of a material to be shaped in all directions without cracking or breaking. This distinguishes it from ductility, which refers to stretching without breaking, and is the correct choice here.
