What is the difference between the outer shell of sodium and the outer shell of fluorine?

The outer shell (the outermost shell) of Na there is 1 electron while in F there are 7 electrons

Further explanation

Given

Sodium and Fluorine

Required

The outer shell difference

Solution

Sodium (symbol Na) is an element in group 1 (alkaline) which has the atomic number 11

So the electron configuration is: [Ne] 3s¹

Meanwhile, Fluorine (symbol F) is a halogen element (group 17) which has atomic number 9

So the electron configuration is: [He] 2s² 2p⁵

If we look at the electron configurations of these two elements, it shows that the element Na to achieve its stability will release 1 electron in the outer shell so that it has an electron configuration like Ne

Meanwhile, Fluorine will need 1 more electron so it can be stable like Ne

So in the outer shell of Na there is 1 electron while in F there are 7 electrons

Variables,control,conclusion and finally scientific theory

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
