2. Only 2
3. Both 1 & 2
4. Neither 1 nor 2

Answer 1

Correct Answer - Option 1 : Only 1

The correct answer is Only 1.

• In the Modem Periodic Table, the arrangement of elements is based on their increasing atomic number in the horizontal rows.
• The Modem Periodic Table is used to predict the properties of elements.
• Even the properties of those elements can be predicted which have not yet been discovered.

• Elements in the modern periodic table are arranged in 7 periods and 18 groups.
• Horizontal rows are called periods and vertical columns are called groups.
• According to their shared physical and chemical properties, the elements can be grouped into the major categories of metals, metalloids and nonmetals.
