Calcium reacts with oxygen to form an ionic bond.
An ionic bond by definition is the kind of chemical bond formed when there is a complete transfer of valence electrons from one atom to another, generating two oppositely charged ions.
In ionic bonding, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons and becomes a negatively charged anion.
Calcium has two electrons in its valence or outermost shell while oxygen has 6 electrons. Calcium gives up these two electrons and becomes positively charged and oxygen accepts them and becomes negatively charged forming an ionic bond resulting in a new compound called calcium oxide.
It is the third one this is simple
Answer:
a Control Variable in an experiment remains the same.
86198Rn => 24He + 84194Po
The radon is shown on the left, and the alpha particle, which is a helium nucleus, is shown of the right with the polonium.
