Explanation:

This is a chemistry - themed crossword puzzle. Each clue refers to a term or concept related to the periodic table and atomic structure. For example, the sum of protons and neutrons gives the atomic mass (clue 1 across). Group 17 elements are halogens, columns are groups, elements 58 - 71 are lanthanides, Group 1 elements are alkali metals, mercury and bromine are liquids at room temperature, neutrons have no charge, semi - conductors are a type of element, elements 90 - 103 are actinides, carbon etc. are non - metals, the center of the periodic table has transition metals, Group 2 metals are alkaline earth metals, Group 18 elements are noble gases, rows are periods, metals are good conductors, electrons are negatively charged and protons are positively charged.

Answer:

1. Atomic mass
2. Halogens
3. Groups
4. Lanthanides
5. Alkali metals
6. Liquid
7. Neutrons
8. Semi - conductors
9. Actinides
10. Non - metals
11. Transition metals
12. Alkaline earth metals
13. Noble gases
14. Periods
15. Metals
16. Electrons
17. Protons
