Why are the Group 18 on the periodic table are stable?

because they all have a full (8 electrons) in their outer shells. every atom "wants" to have a full outer shell, that's why they will react with other elements in order to gain or loose elections. but because the Noble gases have full outer shells, they dont want to react with other elements.

What times what is 18 that adds up to -25?

use equations like this... xy = 18 x + y = -25 solve for y in one of the equations and then substitute. y = 18/x x + (18/x) = -25 x 2 + 18 = -25x x 2 + 25x + 18 = 0 use quadratic equation to find the answer... x = -24.25727602 and -0.742023985

What is a number x added to 18?

A number x added to 18 would be written x + 18. The value * of x + 18 would depend on the value x. For example, if x was 2, x + 18 would equal 20. if x was 10, x + 18 would equal 28, and so on. * 'Value' means what actual number it comes to.

What is group 18 in the periodic table called and why?

These are the "noble gases." They are chemically inert, becausethey have a full octet of electrons in their valence energy level.Therefore, they do not need to lose or gain electrons to achievestability; rather, they are naturally stable, which is why they donot react.
