Answer 2

## Step 1
The vertical columns on the periodic table are called "groups" or "families". These groups contain elements that have similar chemical properties.

## Step 2
The horizontal rows on the periodic table are called "periods". Elements in the same period have the same number of atomic orbitals.

## Step 3
The number of protons in an atom is that element's "atomic" number. This number determines the identity of an element.

## Step 4
The number of protons and neutrons in an atom is that atom's "mass" number. This number gives the total number of particles in the nucleus of an atom.

## Step 5
The ability of a material to be drawn into a thin wire is called "ductility".

## Step 6
The ability of a material to be pounded into thin sheets is called "malleability".

## Step 7
The elements in groups 3 through 12 are called the "transition metals".

## Step 8
The elements in group 1 are called the "alkali metals".

## Step 9
The elements in group 2 are called the "alkaline earth metals".

## Step 10
The elements in group 18 are called the "noble gases".

## Step 11
The elements in group 17 are called the "halogens".

## Step 12
The elements in group 1 are the most reactive metals.

## Step 13
The elements in group 17 are the most reactive nonmetals.

## Step 14
The elements in group 18 are very unreactive.

## Step 15
The elements in group 1 react very violently with water.
