Sodium Atom has a larger atomic radius than chlorine, because as we go across the period the nuclear charge (charge on the atom) increases, also outermost electrons occupy the same principle energy level as we go across the period(3 sub energy level) so the electrons in chlorine are held more closely and tightly together than that of sodium....so sodium has a larger atomic radius

Why percentage of nitrogen is very high in air?
Because that's how much there is, even if there were more oxygen in air than nitrogen this would be unhealthy!
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
Is nitrogen heavier than oxygen?
it is heavier
What planet has nitrogen and oxygen in it's atmosphere?
It is none other than our own planet Earth, which has nitrogen and oxygen in its atmosphere.
Why did god made nitrogen more abundant than oxygen?
oxygen is used by human and animals for respiration but nitrogen do not. for consuming nitrogen plants need nitrogen fixation thus occurs on low scale on other hand oxygen is directly used so its cunsumbtion is more then nitrogen. another important point is that oxygen is used in burning, formation of water etc thus means ratio of cunsumbtion of oxygen is more then nitrogen ,if there was more oxygen then it would lead to a blast every time there was a spark
What percentage of air is made of nitrogen than oxegyn makes upthe air?
Nitrogen 78% , Oxygen 21%.
Does oxygen have the highest percentage by volume in dry air than nitrogen carbon dioxide or hydrogen?
You're looking for Nitrogen

Why is it that the nitrogen have greater amount than oxygen?
nitrogen is lighter than oxygen
What is lighter oxygen or nitrogen?
Nitrogen is lighter than oxygen
Does oxygen effuse 1.07 times faster than nitrogen?
No, nitrogen effuse faster than oxygen.
How many Time more nitrogen than oxygen make up air?
There is: Nitrogen (N2): 78.09% Oxygen (O2): 20.95% in the atmosphere There is ~3.73 times more oxygen than nitrogen in the air and is in a ratio (oxygen to nitrogen) of 39:10 (rounded).

Why does the nitrogen gas has higher amount than that of oxygen gas?
bcoz oxygen is used by living beings were nitrogen is not used.
When the nucleus of a nitrogen atom absorbs a proton the resulting element is?
Oxygen, the element with an atomic number higher by one than that of nitrogen.
