Which among them is the biggest atom? Element Electronic configuration H 1 Li 2, 1 Na 2, 8, 1 K 2, 8, 8, 1 Rb 2, 8, 18, 8, 1 Cs 2,8, 18, 18, 8, 1 Fr 2, 8, 18, 32, 18, 8, 1

Francium is the biggest atom among the above-given elements. It has seven shells, but hydrogen has only one shell. The size of the atom increases as we move down the group. As we move from top to bottom of a group in the periodic table, the size of the atom increases as there is an increase in the number of shells. The size of the atom decrease as moves across the period because of the increase in nuclear charge and shells remain the same.

Which among them is the smallest atom? Element Electronic configuration H 1 Li 2, 1 Na 2, 8, 1 K 2, 8, 8, 1 Rb 2, 8, 18, 8, 1 Cs 2,8, 18, 18, 8, 1 Fr 2, 8, 18, 32, 18, 8, 1

Hydrogen is the smallest atom among the above given elements. It has only one shell, but francium has seven shells. The size of the atom increases as we move down the group. As we move from top to bottom of a group in the periodic table, the size of the atom increases as there is an increase in the number of shells. The size of the atom decrease as moves across the period because of the increase in nuclear charge and shells remain the same.

What happens to the size of the atom when we move down the group? Element Electronic configuration H 1 Li 2, 1 Na 2, 8, 1 K 2, 8, 8, 1 Rb 2, 8, 18, 8, 1 Cs 2,8, 18, 18, 8, 1 Fr 2, 8, 18, 32, 18, 8, 1

The size of the atom increases as we move down the group. Hydrogen has only one shell but francium has seven shells. As we move from top to bottom of a group in the periodic table, the size of the atom increases as there is an increase in the number of shells. The size of the atom decrease as moves across the period because of the increase in nuclear charge and shells remain the same.

What happens to the size of the atom when we move down the group? What is the reason for this? Element Electronic configuration H 1 Li 2, 1 Na 2, 8, 1 K 2, 8, 8, 1 Rb 2, 8, 18, 8, 1 Cs 2,8, 18, 18, 8, 1 Fr 2, 8, 18, 32, 18, 8, 1

The size of the atom increases as we move down the group, it is because the number of shells increases. Hydrogen has only one shell but francium has seven shells. As we move from top to bottom of a group in the periodic table, the size of the atom increases as there is an increase in the number of shells. The size of the atom decrease as moves across the period because of the increase in nuclear charge and shells remain the same.

Are there an increase in the number of shells with an increase in atomic number in the table given below? Element Li Br B C N O F Atomic number 3 4 5 6 7 8 9 Number of shells 2 2 2 2 2 2 2

No, there is no increase in the number of shells across the period with an increase in atomic number, they remain the same. The number of shells remains the same across the period but increases down the group. The atomic number is equal to number of protons. Protons carry one unit positive charge. As the atomic number increases across the period positive charges increases, but shells reaming the same. The size of the atom decreases due to an increase in the positive charges across the period.
