How can you use the periodic table to find the atomic number of an element?

Answer 1

The atomic number of an element can be determined by using the periodic table. The periodic table arranges elements in order of increasing atomic number. Each element on the periodic table is assigned a unique atomic number, which represents the number of protons in the nucleus of an atom of that element.

To find the atomic number of an element using the periodic table, follow these steps:

1. Locate the element of interest on the periodic table.
2. The atomic number of the element is typically displayed above or below the elemental symbol.
3. The atomic number is usually an integer and is specifically assigned to that particular element.

For example, to find the atomic number of carbon (C), locate the element C on the periodic table. The atomic number of carbon is 6, as indicated on the periodic table.
