Question

for each compound, click the camera ( ) icon to take a snapshot. right - click the image, and click copy image. paste each image into a blank document to turn in with this worksheet. write the ionic charges (such as ca²⁺) and chemical formulas below.
a. lithium and fluorine:
ionic charges: li + f -
chemical formula: lif
b. beryllium and oxygen:
be 2 o 2
beo
c. magnesium and fluorine:
mg 2+ f -
mgf2
d. aluminum and chlorine:
al 3+ cl -
alcl3
e. beryllium and nitrogen
be n

Explanation:

Step1: Determine beryllium ion charge

Beryllium is in group 2, loses 2 electrons, so charge is $2+$.

Step2: Determine nitrogen ion charge

Nitrogen is in group 15, gains 3 electrons, so charge is $3 -$.

Step3: Write chemical formula

Cross - multiply charges to get $Be_3N_2$.

Answer:

Ionic charges: Be $2+$, N $3 -$; Chemical formula: $Be_3N_2$
