1s^2 2s^2 2p^6
This is the electron configuration of 02-
It is also known as noble gas like configuration and in general it is stable if oxygen is like that in a compound (8 electrons in its 2s and 2p orbitals combined)
<span>Earth's gravitational potential energy: GPE = mgh = Gravity (9.81m/s2) × Mass (kg) × Height (m)
it's k</span><span>inetic energy</span>
It would be potassium chloride or kcl
The Alkali metals are Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium. There may be Hydrogen as well, it really depends if the teacher considers it a metal. The Alkalis are the far left column on the periodic table. If you don't have a paper copy, www.ptable.com is a good resource.
