The NA+ ion has less electrons and therefore, the positive charge on Na+ is greater, pulling the electrons closer to the nucleus. Therefore, if the electrons move closer to the nucleus the radius will decrease.
Not only this, but the Na ion also drops a valence level because it only has one electron on its outer valence level. Therefore, another solution is that if the valence level drops, the radius drops as well
Hope this helped!!:D
Hey there!
1 mol is 6.022 x 10²³ formula units.
To find the amount of formula units in 5.81 mol of BaCl₂, we need to multiply the amount in 1 mol by 5.81.
5.81 x 6.022 x 10²³
35.0 x 10²³
3.40 x 10²⁴
There are 3.4 x 10²⁴ formula units in 5.81 mol BaCl₂.
Hope this helps!

Answer/Explanation
Characteristics of Life Present in Viruses:
- has a defined boundary - viruses are made up simply of genetic material surrounded by a<u> protein capsid </u>and sometimes a lipid membrane
Characteristics of Life Absent in Viruses:
- made up of one or more cells - one of the main arguments for why viruses are not living is that they are <u>not cellular</u>
- uses energy - this is a tricky one. They don't use or produce their own energy. However, in order to reproduce they do hijack the host cells and <u>steal energy</u> from them in order to reproduce
- exhibits growth and development - although viruses do <u>reproduce</u>, the individual viral particles do not exhibit growth or development
- possess internal organisation - other than the fact they ahve genetic material, the inside of a virus does not contain internal organization like a cytosol, instead conssiting of the bare minimum amount of proteins to survive
- eliminates waste - since they do not have their own metabolism, they have no waste to eliminate
