Answer 2

Two factors that influence the periodic properties of elements in groups and periods are atomic size and ionisation energy.

• In the modern periodic table, elements are arranged in increasing order of their atomic number. rows in which elements arranged horizontally are known as periods whereas vertical arrangement is groups.
• In the modern periodic table, there are 18 groups and 7 periods, which determine the properties of elements.
• Properties such as atomic size, ionisation energy, and electron gain enthalpy all affect the periodic properties of elements.
• Atomic size increases down the group because nuclear charge decreases and the number of shells increases down the group.
• Ionisation energy decreases down the group because the decrease of nuclear charge electrons is far from the nucleus, so, it can be isolated easily on going down the group.
