Explanation:
Once one shell is full, the next electron that is added has to move to the next shell. So... for the element of NEON, you already know that the atomic number tells you the number of electrons. That means there are 10 electrons in a neon atom.
MH₂ = 2×mH = 2×1g = 2 g/mol
526 L O2 x 1 mol O2 / 22.4 L = 23.5 mol O2
The volume of object is 3.2 ml
<h3>Explanation:</h3>
Given:
Mass of the object = M = 9.6 g
Initial volume of liquid: 
Final volume of liquid after displacement: 
Total volume of the displaced object inside a graduating cylinder will be given as difference between the final volume and initial volume of the expanding object.

V = 3.2 ml
