Answer:
lost 2 electrons
Explanation:
A <em>cation</em> by definition is a positively charged ion. They are formed when a metal loses its electrons. A cation has more protons than electrons, giving it a net positive charge. So, it had to have lost 2 electrons to give it a positive charge of 2⁺.
Answer:
D.) All of the above

Answer:
Ca
Explanation:
As a general trend on the periodic table, the electronegativities of elements decrease down the group and increase across the periods. Since calcium is in group two , it is expected to have the lowest amount of electronegativity due to its specific location on the periodic table.
To show that this prediction is true, I will write the elecronegativity values of these atoms. Calcium has a value 1.0, Silver 1.93 , Iron 1.83 and chromium 1.66
Answer:
C
Explanation:
The answer is shape.
Basically, quantities can either be fundamental or derived. While fundamental are the basic quantities, derived are obtained from combining fundamentals.
To get a shape, we would need the combination of lengths. This makes the shape a derived quantity
