Question

The elements present in 16th group​

Answer 1

Answer:

The elements present in 16th group are Oxygen, Sulphur, Selenium, Tellurium and Polonium.

Explanation:

In the modern periodic table, the atoms are arranged according to the increasing order of their atomic numbers.

It consists of 7 horizontal rows called periods and 18 vertical columns called groups in a periodic table

There are 5 elements in the 16th group of periodic table. 16th group elements are also called chalcogens.

They are Oxygen, Sulphur, Selenium, Tellurium and Polonium.

The first element in oxygen, with atomic number 8 and chemical symbol is 'O'. It is colorless, odorless gas abundantly found in earth. It helps to support life in earth.

The second element is Sulphur with atomic number 16 and chemical symbol 'S'

The third element is Selenium, with atomic number 34 and chemical symbol 'Se'

The fourth element is Tellurium with atomic number 52 and chemical symbol 'Te'

Answer 2

Answer:

Five elements constitute group 16 of the modern periodic table: oxygen, sulfur, selenium, tellurium, and polonium.

Explanation:

Five elements constitute group 16 of the modern periodic table are:

1. Oxygen,
2. Sulfur,
3. Selenium,
4. Tellurium,
5. Polonium.

Because several of the elements in this group may be recovered from sulfide or oxide ores, they are frequently referred to as chalcogens or ore-forming elements.

The singles of the group 16 elements are O, S, Se, Te, and Po respectively.

The electronic configuration of each element of Group 16 are else follows below:

1. Oxygen - [He] 2s² 2p⁴
2. Sulfur - [Ne] 3s² 3p⁴
3. Selenium - [Ar] 3d¹⁰ 4s² 4p⁴
4. Tellurium - [Kr] 4d¹⁰ 5s² 5p⁴
5. Polonium - [Xe]4f¹⁴ 5d¹⁰ 6s² 6p⁴

The name of the elements that constitute group 16 of the modern periodic table are oxygen, sulphur, selenium, tellurium, and polonium
