Helium doesnot have a gender. It is a chemical element
Helium has the smallest covalent radius
The atomic radius of bromine is lower.
Element b would have a larger atomic radius than element c as you move down a group on the periodic table, the atomic radius tends to increase. This is because each successive element has an additional electron shell, leading to an increase in size.
This element is barium.
Helium is a noble gas, it is colourless, odourless gas at STP. It is a chemically inert element.
Helium doesnot have a gender. It is a chemical element
The element nickel (Ni) has an atomic radius of 124 picometers.
Helium has the smallest covalent radius
The atomic radius is calculated by spctroscopic or X-ray methods.
The atomic radius of bromine is lower.
francium has the largest ionic radius
Element b would have a larger atomic radius than element c as you move down a group on the periodic table, the atomic radius tends to increase. This is because each successive element has an additional electron shell, leading to an increase in size.
Francium has the largest atomic radius of all the elements on the Periodic Table.
