The Calcium atom has 2 valence electrons but a Calcium ion will have no electrons because it is a cation ion. Meaning that there are more protons than electrons. Also, the normal calcium symbol is Ca but the calcium ion is Ca²⁺

I hope this wasn't too late

Answer:

Newton's Second Law

Explanation:

Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

(I'm going to assume this is an option, but please let me know if it's not!)

Question:
finlep [7]

Answer:

Cyclohexene doesn't exhibit this type of Isomerism. Cyclohexene is a tiny ring to exhibit the trans isomer. The Structural formula and component bonding characteristic within it limits it to show this phenomenon. Trying to force it to be trans would place a massive amount of ring strain on the molecule.

This characterises major rings within Alkene group up to cyclooctene.
