Across
- 4. when elements are arranged in order of increasing atomic number; there is a periodic repetition of their physical and chemical properties
- 5. an atom or group of atoms that has a positive or negative charge
- 7. type of element that is a good conductor of heat and electric current which are shiny; malleable; and ductile
- 9. horizontal row of elements in the periodic table
- 12. one half the distance between the nuclei of the distance between the nuclei of two atoms and the same element when the atoms are joined
- 13. type of element that tends to have properties that are similar to both metal and nonmetals
- 14. the energy change when an atom gains an electron
- 15. vertical column of elements on the periodic table
- 16. the energy required to remove an electron from an atom in its gaseous state
Down
- 1. the arrangement of electrons of an atom in its ground state into various orbitals around the atom’s nucleus
- 2. the net positive nuclear charge experienced by an electron in an atom and is not usually the full nuclear charge due to the shielding effect of core electrons
- 3. elements in Groups 1-2 and 13 to 18 of the periodic table that display a wide range of physical and chemical properties
- 6. law which states the strength of the force between two charged particles depends on the charge of each particle and the distance between them
- 8. type of element that tends to be a poor conductor of heat and electric current which has properties that are the opposite of metals
- 10. any atom or group of atoms with a positive charge
- 11. any atom or group of atoms with a negative charge
