Halogens with lower atomic number are more reactive and less dense. Also iodine is solid, bromine liquid and the first halogens are gases.

What is the reactivity for the halogens?
The reactivity of halogens decreases with increasing atomic number.
What decreases across the periodic table?
Atomic size decreases across a period
When you go across the periodic table how does the atomic size go?
Atomic size decreases across the rows of the periodic table
What happens to the atomic radius as you from the bottom to the top of the periodic table?
The atomic radius decreases.
What happen to the atomic radius as move from the bottom to the top of the periodic table?
The atomic radius decreases.
What is halogens atomic number?
The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What element from the periodic table starts with the letter I?
Iodine from periodic table is represented by I.It has 53 atomic number.It belongs to group of Halogens.
How does the atomic raduis change across a period of the periodic table?
Atomic radius usually decreases from left to right across a period of the periodic table.
How does the atomic radius increase or decrease horizontally on the periodic table?
Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.
What make the atomic radius change along the periodic in periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.
What makes the atomic radius change along the periodic in the periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.
Does atomic size increase from left to right across the periodic table?
it decreases
