Chemistry - Semester 1 Final Exam Review

Front

What type of bond is formed when electrons are transferred between atoms?

Back

Ionic bond.

Front

What is the primary characteristic of a covalent bond?

Back

A covalent bond is formed when two atoms share electrons.

Front

What type of bond forms between hydrogen (H) and bromine (Br)?

Back

Covalent bond.

Front

How many protons does copper (Cu) have?

Back

29 protons.

Front

What is the definition of an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of charged ions.

Front

What is the significance of protons in an atom?

Back

Protons determine the atomic number and identity of an element.

Front

What is the difference between a metal and a non-metal in terms of bonding?

Back

Metals tend to lose electrons and form ionic bonds, while non-metals tend to gain electrons and form covalent bonds.

Front

What is the role of electrons in chemical bonding?

Back

Electrons are involved in forming bonds between atoms, either by being shared (covalent bonds) or transferred (ionic bonds).

Front

What is a metallic bond?

Back

A metallic bond is a type of bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move.

Front

What is the general trend of reactivity in metals?

Back

Reactivity in metals generally increases as you move down a group in the periodic table.
