Review of Chemistry and Introduction to Organic Chemistry

The label A is pointing at the:

• Atom

• Nucleus

• Electrons

• Protons

The label B is pointing at the:

• Atom

• Nucleus

• Electrons

• Protons

The label C is pointing at the:

• Atom

• Nucleus

• Electrons

• Protons

The nucleus makes up…

• Most of the atom

• 50% of the total atomic volume

• 25% of the total atomic volume

• < 0.1 % of the total atomic volume

Many of the chemical properties of an atom and its chemical reactivity are determined by the…

• Electrons

• Protons

• Neutrons

• Nucleus

Valence shell electrons are...

• The outermost shell of electrons

• The electrons that participate in chemical bonding and reactions

• Able to be lost or gained to stabilise an atom (in some cases)

• All of the above

An ionic bond is one in which:

• Atoms lose or gain electrons to become ions, and are attracted to each other through electrostatic forces

• Electrons are shared between atoms so that each can achieve a full valence shell

• Any two atoms bond together to form a molecule

• Atoms are held together by the force of their protons

A covalent bond is one in which:

• Atoms lose or gain electrons to become ions, and are attracted to each other through electrostatic forces

• Electrons are shared between atoms so that each can achieve a full valence shell

• Any two atoms bond together to form a molecule

• Atoms are held together by the force of their protons

Organic chemistry is...

• The study of carbon compounds

• The study of all natural compounds

• The study of the chemistry of living things

• The study of sustainably sourced chemistry

The main elements involved in organic molecules are:

• Carbon and oxygen

• Hydrogen and oxygen

• Carbon and hydrogen

• Carbon and nitrogen
