Inorganic Chemistry
1. A subatomic particle with a single positive electrical charge is protons.
2. A subatomic particle with a single negative electrical charge is electrons.
3. A subatomic particle which is electrically neutral is neutrons.
4. The nucleus of an atom is made up of _protons_ and _neutrons.
5. The number of electrons forming a charge cloud around the nucleus is (pick one of the following) greater than; equal to; smaller than the number of protons in the nucleus of the atom.
6. The atomic number of potassium (3919K) is_19_. This means that a potassium atom has _19 protons and 19_ electrons.
7. What is the atomic mass of K? ___39________.
8. The atomic mass represents the number of _protons_ and _neutrons.
9. The isotope 14C differs from 12C in that 14C has (pick one of the following) more; less; same) neutrons.
10. Electrons are arranged in electron shells. The electron shell closest to the nucleus has a maximum capacity of _2___ electrons, whereas the second shell holds a maximum of _8__ electrons for elements in Biology.
11. The outermost shell is referred to as the __valance__ shell. The electrons in the outermost shell are referred to as the _valance_ electrons.
12. Trick Question: How many electrons does 42He need to be stable? _It is balanced__
13. How many electrons does 3919K need to be stable?___________
14. How will K most likely become stable (what does it need?) __¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬__
15. Ions are atoms that have (pick one): gained or lost; shared one or more electrons into or form their valence shells.
16. A cation is an atom that has (gained or lost) an electron. (Pick one)
17. An anion is an atom that has (gained or lost) an electron (Pick one)
18. When a cation bonds with an anion, that bond is referred to as a/an _ionic_ bond.
19. Circle the molecules that are classified as compounds (H, H2, H2O, C6H12O6, N2)
20. Find the name for each element using the periodical
