Across
- 1. the type of alkali metals in group 2A on the periodic table
- 5. this type of energy is the energy required to remove an electron from an atom
- 8. this law states that when elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties
- 9. an ion with a negative charge
- 11. the ability of an atom of an element to attract electrons when the atom is in a compound
- 13. this type of radius is one half of the distance between the nuclei of two atoms of the same element when the atoms are joined
- 15. the type of element that has properties similar to metals and nonmetals
- 16. the type of gases in group 8A on the periodic table that are sometimes called the inert gases because they rarely take part in a reaction
- 17. an atom or group of atoms that has a positive or negative charge
