Which of the following has the smallest atomic radius?
a B
b Al
c F
d N
e Ga
Answer:
c. F
Explanation:
As you go top to bottom down a column of the periodic table, atomic radius increases.
As you go left to right across a period of the periodic table, atomic radius decreases.
Knowing this trend, that means that the smallest atomic radius would be located in the top right of the periodic table. The closest element to that point is fluorine, or answer C.

Will mark brainliest thank you!!
Answer:
Explanation:
Using Charles Law ,
[tex]\frac{V1}{T1}=\frac{V2}{T2}[/tex]
Using this formula we have ,
V1= 200cm^3
T1=40+273.15 = 313.15 K
T2 = 100+273.15 = 373.15 k
V2= ?
Hence using above formula simplify it we will get ,
V2 = 238.3 cm^3
