Question

The atoms of the elements in the periodic table are arranged in order of increasing number of

Answer 1

A table in which the chemical elements are arranged in order of increasing atomic number. Elements with similar properties are arranged in the same column (called a group), and elements with the same number of electron shells are arranged in the same row (called a period).

Answer 2

The elements are listed in the modern periodic table in increasing order of atomic number.

• The number of protons in an atom's nucleus is known as the atomic number.
• The number of protons in an element allows for identification.
• The number of electrons around the nucleus is determined by the number of protons, and the arrangement of these electrons determines the majority of an element's chemical activity.
• Each element has a certain quantity of electrons. Two elements cannot have the same atomic number.
• As a result, elements may be simply sorted according to increasing atomic number.
• Similar chemically characterized elements naturally arrange in the same column or group.
• For instance, every element in Group 1A is a relatively soft metal that reacts strongly with water and has a valency of +1.
• Whereas every element in Group 8A is a monatomic gas that is non-reactive and stable at room temperature.
