Metallic and Covalent Bonding (Q2W3)

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two non-metal atoms share pairs of electrons.

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that represents the valence electrons of atoms within a molecule, showing how they are shared or transferred.

Front

What is the molecular formula for phosphorus trichloride?

Back

PCl₃

Front

What type of bond is formed between two non-metal atoms?

Back

Covalent bond.

Front

How many electrons are shared in a nitrogen molecule (N₂)?

Back

6 electrons (3 pairs).

Front

What is the correct structure for BF₃?

Back

The correct structure is represented by Option C.

Front

What is the difference between metallic and covalent bonding?

Back

Metallic bonding involves the sharing of free electrons among a lattice of metal atoms, while covalent bonding involves the sharing of electrons between non-metal atoms.

Front

What is a triple bond?

Back

A triple bond is a type of covalent bond where three pairs of electrons are shared between two atoms.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms.

Front

What is the general rule for determining the number of bonds an atom can form?

Back

An atom can form as many bonds as it has unpaired valence electrons.
