Answer 2

Answer:

The periodic table is a way of arranging the elements so patterns in their properties and reactions can be identified and explained. Most elements are metals. The noble gases are very unreactive.

All the different elements are arranged in a chart called the periodic table.

Here are the main features of the table:

• the horizontal rows are called periods

• the vertical columns are called groups

• elements in the same group are similar to each other

• the metals are on the left and the non-metals are on the right (hydrogen is a non-metal but is often put in the middle)

• the main groups are numbered from 1 to 7 going from left to right, and the last group on the right is Group 0

• the block in between Group 2 and Group 3 is where the transition metals are placed

• there are only two elements in Period 1 (hydrogen and helium)
