select all that apply.

- into periods or horizontal rows that share a pattern
- by order of relative abundance of the element on earth
- into order of densities from lowest to highest
- into vertical groups of elements that have similar physical and chemical properties
- by increasing order of atomic number

The following statements apply:

1. Into periods or horizontal rows that share a pattern.

2. Into vertical groups of elements that have similar physical and chemical properties.

3. By increasing order of atomic number.

The periodic table of elements is made up of all the known elements and these elements are arranged in the table based on their atomic numbers, starting with the element with the lowest atomic number, which is hydrogen. All the elements in the table are arranged in rows and columns; the rows runs from left to right and are called periods while the columns run up and down and are called groups. Elements in the same group share similar properties.
