Bonding and Nomenclature, FM, % comp, EF and MF Review

Front

How do covalent bonds form?

Back

Covalent bonds form by sharing valence electrons between atoms.

Front

What do metals tend to do with electrons?

Back

Metals tend to lose electrons.

Front

What is the name of the acid HC₂H₃O₂?

Back

Acetic Acid.

Front

What is the molar mass of CO₂?

Back

44 g/mol.

Front

What do nonmetals tend to do with electrons?

Back

Nonmetals tend to gain electrons.

Front

Define ionic bond.

Back

An ionic bond is formed when one atom donates an electron to another atom, resulting in attraction between oppositely charged ions.

Front

What is the difference between empirical formula (EF) and molecular formula (MF)?

Back

The empirical formula shows the simplest whole-number ratio of elements in a compound, while the molecular formula shows the actual number of atoms of each element in a molecule.

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 formula for calculating percent composition?

Back

Percent composition = (mass of element in 1 mole of compound / molar mass of compound) x 100%.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged species composed of two or more atoms covalently bonded together.
