Chemistry and Biochemistry Exam
Questions & Answers (Grade A+)
Charged (Unequal # of Protons and Electrons) -
correct answer ✅Ions
Are Ionic Bonds strong? -
correct answer ✅No, they are weak
What is a cation? -
correct answer ✅Positively charged Ion
What is an anion? -
correct answer ✅Negatively charged Ion
Name the different atoms and their charges and location: -
correct answer ✅Protons:Positive (In Nucleus) Neutron:Neutral
(Nucleus)
Electron:Negative (In the energy levels)
You want to have same number of protons, neutron, and electrons.
