Chemistry unit test 3

Kind of mineral substances.

Chemical elements that are not metals.

Chemicals elements with some of the properties of metals/non-metals.

Normal metals (group 3 -> group 12).

They are very reactive (group 1 except hydrogen).

Reactive but not so much as the alkali metals (group 2).

Non reactive non-metals (group 18).

Very reactive non-metals (group 17).

The vertical row of the periodic table and has properties of elements in the same ______ are similar.

The horizontal row of the periodic table and has properties of elements change accross a _____.

When elements are arranged in order of increasing atomic number, there are repeating patterns in their physical/chemical properties

Materials that let heat and/or electricity past through.

You can change the shape of a material without breaking it.

Can be bent or stretched easily

Delicate and easily broken.

Not shiny.

Metals are ____ conductors of heat and electricity. They are also m__, d___ and have a ____ surface. Because metals are ___ at room temperature so they have ___ melting points.

Most nonmetals are ___ at room temperature, but some are b___ and d___ solids. They are ____ conductors of heat and electricity.

Metalloids are _____ to metals in someways, and _____ to nonmetals in other ways.

The periodic table was created in ____

In the modern periodic table, elements are arranged by the _____ of . They are laid out in g and p_ that highlight patterns in their chemical/physical properties.

The characteristics you can observe/measure without changing what the substance is made of.

How a substance forms compounds with other substances (you cannot observe/measure this without changing what the substance is made of)

Types of ions are usually formed by metals and have positive charge.

Types of ions are usually formed by nonmetals and have negative charge.

An atom that has a positive/negative charge because it has gained/lost electrons. Atoms achiece a stable noble gas electron configuration by either losing all their valence electrons/gaining enough electrons to fill up their outer energy level.

The elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons.

The energy needed to remove an electron from an atom (measured in k/mol).
