Answer:
Electrons repel each other due to electrostatic force of attraction between both of them as a result prevent the electron from entering the nucleus preventing it from collapsing
Answer:
Rate of Ar= 1.65 x mol/h
Explanation:
Here we'll use Graham's Law where
R= rate of effusion and M= molar mass
Let's plug in what we know.
You could switch them where Xe is M1 (on the bottom) instead of M2, but I find it easier when the unknown is R1, where it acts like a whole number. It makes the algebra part of the equation easier.
Let's solve for R1.
R1= 1.089 x
R1= 1.65 x mol/h
Answer:
increase in the size of fruits and vegetables
If you look at the Periodic Table of Elements, all three of those qualities increase as you move from left to right and bottom to top, so that they are max at the top right corner.
In your question all three qualities are low, so the element is likely in the bottom left portion of the table.
