Which has the largest atomic radius magnesium silicon sulfur or sodium the smallest

Therefore the largest atoms are on the left and the smallest on the right. So sodium (Na) has the largest atomic radius, as the valence electrons are the least attracted to the nucleus

PLEASE MARK ME AS BRAINIEST AND ADD ME AS FRIEND HOPE THIS HELPS AND GIVE G M A I L

D. 2.40 atm

Explanation:

At constant temperature and number of moles, using Boyle's law  

Given ,  

V₁ = 0.250 L

V₂ = 0.125 L

P₁ = 1.20 atm

P₂ = ? atm

Using above equation as:

- D. 2.40 atm
