When a metal bonds with another non-metal an ionic bond is formed
I love these type of questions :)
Final Answer: Neon
Just look it up on goog^le or a chart
I would say the energy has to be decreased by 87 kj because the bonding is held together by 87 kj so removing that should prevent the bonding from taking place or reverse it I believe. In other words, a certain amount of energy is required to hold the bond together and in the absence of that energy, the bonding will not take place.
It is a <u>mixture</u> of minerals mainly of corps that crystalizes of magma below earths surface.
