Elements + Periodic Table

4. a series of nonmetal elements from group 17 of the periodic table. Is the only periodic table group which contains elements in all three familiar states of matter at standard temperature and pressure.
7. any metal in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table.
10. Are called this because they are the lighter elements in the series of metals and are chemically similar to lanthanum.
11. elements with ties to nuclear power. series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium.
13. are a group of chemical elements in the periodic table with very similar properties: they are all shiny, soft, silvery, highly reactive metals at standard temperature and pressure[1] and readily lose their outermost electron to form cations with charge +1.
14. (Ba), and radium (Ra).[4] This group lies in the s-block of the periodic table as all alkaline earth metals have their outermost electron in an s-orbital.

1. the chemical bond that involves the sharing of pairs of electrons between atoms (This is how Compounds are formed).
2. vertical organization of elements that have the same number of electrons.
3. horizontal rows of elements that contain increasing numbers of protons and electrons.
5. these metals are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), bar
6. are the outer-most electrons of an atom that can participate in the formation of chemical bonds with other atoms.
8. this "number" is the number of protons in an atom
9. have some properties of both metals and nonmetals.
12. these gases are known for their extremely low level of reactivity. Also known as "rare gases"
