Answer:
metal calcium or (Ca).
Explanation:
For example, the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl2). In this compound, there are two negative chloride ions for each positive calcium ion
The sum of the percentage abundance of these two isotopes of the new synthetic element should be equal to 100. If we let x be the percent abundance of the second isotope, we have the equation,
62 + x = 100
The value of x from the equation is 38.
Answer:
you know it is what it is☠
Explanation:
Nonmetallic elements form ions by valence electrons to complete their outer shell. The valence electrons an element has in its outer shell, the easier it is to complete. The electron shells an element has, the easier it is to fill its outermost shell.
