The nonmetal in period three with properties similar to iodine is chlorine. Chlorine is in the same group (halogens) as iodine and shares similar chemical properties such as being highly reactive and forming compounds easily.
Three non-metals that share very similar chemical properties are nitrogen, phosphorus, and arsenic. They are all located in the same group on the periodic table (Group 15), known as the nitrogen group, and exhibit similar reactivity and bonding characteristics.
They have congruent angles, they are multiplied by a scale factor, and they are the same shape
Iron , cobalt and Nickel families of periodic table show the similar properties. these families are in three different columns but are considered as one group.
It is then 2.64 when rounded to three significant figures
Figures in three dimensions are known as solids.
There are three significant figures in 36.7.
Three elements that have similar chemical properties to oxygen are sulfur, selenium, and tellurium. These elements belong to the same group as oxygen in the periodic table and have similar electron configurations, which influence their reactivity and chemical behavior. Additionally, they can form similar types of chemical bonds with other elements.
Lithium (Li), potassium (K), and cesium (Cs) have similar properties to sodium as they are all alkali metals with one valence electron. They react similarly with water and oxygen, forming similar compounds and exhibiting similar chemical behavior.
There are 4 of them
