Answer:
If it loses to electrons the net charge will be +2. If the atom instead gains 4 electrons, the net charge will be -4.
Explanation: When an atom loses electrons( which are negatively charged), it turns into a cation. This means since there is more protons(which are positively charged) than electrons, the charge is positive. The charge is positive and than the number of electrons lost. It is the exact opposite for gaining electrons.
16 and 6
Explanation:
the top number will be 16 and the bottom number will be 6
All the conversions have a net value of 1
Mole is mass (g) / Molar mass (mole/gram)
So to find mass in gram multiply the no.mole by Molar mass
