Question

What do you mean by groups and periods​

Answer 1

Explanation:

Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.

Answer 2

GROUPS

• The vertical columns in the Periodic Table are called groups.
• There are 18 groups in the Periodic Table.
• Moving down in a group, Metallic character increases.
• Nucleic radii also increases moving down in a group.
• Group 1 and 2 are s block elements.
• Group 13 - 18 are p block elements.
• Group 3 - 12 are d block elements.
• Group 3 consists of Lanthanide and Actinides, called f block elements.

PERIODS

• The Horizontal rows in the Periodic Table are called Periods.
• There are 7 periods in the Periodic Table.
• Moving from left to right in a Periodic Table, non metallic character increases.
• Nucleic radii also increases moving from left to right in the Periodic Table.
