Science Review

Quantitative describes properties of matter using measurements. Qualitative describes properties of matter using senses. Ex. Length, smell

No open-toe shoes, long hair tied back, and no food or drinks. Lab rules must be followed the keep everyone safe and protected from injury or death.

Eye wash station and shower.

Anything that has a mass or volume. Solid

Substance with one type of particle and 1 set of physical and chemical properties. Salt

Substance made of one atom, found on periodic table. Lithium

2 or more elements chemically bonded. Water

Substance with 2 or more pure substances mixed. Trail mix

Substances are unidentifiable, evenly mixed. Coffee and milk

Substances are identifiable, not mixed well. Sand

Sink in water if it has a higher density than water, will float if its density is smaller than water.

Transfer of heat, change in colour, bubbles/fizzing, and odour/scent.

An atom is a single, tiny particle. A molecule is a group of 2 or more atoms of the same element held together by chemical bonds. A compound is a substance made from 2 or more different elements chemically bonded together.

Horizontal rows on the periodic table and tells you how many electron orbitals an element has.

Vertical columns on the periodic table that tell you the number of valence electrons those elements have.

Gases that are located on the right side of the periodic table.

Solids that are located in the zigzag staircase on the periodic table.

Solids located on the left side of the periodic table.

In group 1, one valence electron, are highly reactive and have a low melting point.

In group 2, 2 valence electrons, shiny, silvery, and bright colours.

In group 17, highly reactive with 7 valence electrons, can be poisonous.

In group 18, unreactive with full valence shells, non-toxic.

Positively charged subatomic particle, located in the nucleus of the atom.

Negatively charged subatomic particle, located in the orbitals surrounding the atom.
