1. protons, neutrons, and electrons are ______ particles.
2. the subatomic particle that has no electrical charge is the ______.
3. each type of subatomic particle has a different electrical ______.
4. hydrogen, helium, sodium and chlorine are examples of ______ elements.
5. the piece of the atom that has an electrical charge of -1 is ______.
6. each chemical element consists of only one type of ______.
7. the chemical element with 109 protons is ______.
8. another name for atomic weight is atomic ______.
9. if we want to know how many electrons and protons an element has, we can look at the ______ table.
10. the only atom that does not contain a neutron is a ______ atom.
11. neutrons and protons are located in the atoms ______.
12. electrons are very small ______ located outside the nucleus.
13. all atoms with the same number of ______ in the atomic nucleus are the same element.
14. the six major ______ in the living things are carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur.
15. atoms are one of the smallest units of ______.

Explanation:

These are basic concepts in chemistry related to atoms and sub - atomic particles. We use common chemistry vocabulary to fill in the blanks. For example, protons, neutrons, and electrons are well - known subatomic particles. Neutrons are neutral in charge. Electrons have a negative charge of - 1 and are located outside the nucleus. Elements are made up of atoms and the periodic table helps in determining the number of electrons and protons in an element.

6. atom
7. meitnerium
8. mass
9. Periodic
10. hydrogen
11. nucleus
12. particles
