The (2) calcium atom, because when looking at the periodic table, we see that the calcium atom is in a location where according to the periodic table, has the lower electronegativities in respect to the other three choices. We see that it also has a lower electronegativity value than the others. Electronegativity is the attraction constant for the electrons in a chemical bond. The higher the electronegativity, the higher the attraction of the electrons. Fluorine has the highest electronegativity with 4.0.

What is an ionic bond
Pani-rosa [81]
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

A sample of 0.370 mol of a metal oxide (m2o3) weighs 55.45 g. how many grams of o are in the sample?
Wewaii [24]
0.370 mol metal oxide = 55.45 g 

<span>1 mol = 55.45/0.370 = 149.86 g </span>

<span>in 1 mol there are 3 mol O = 16 * 3 = 48 g of O </span>

<span>there is 48/149.86 * 100% O in the sample </span>

<span>the sample has 48/149.86 * 0.370 = 0.119 g O</span>
