Science Assessment
Across
- 2. an element that lacks most of the properties of a metal; these are found on the right-hand side of the zigzag line on the periodic table
- 6. a negatively charged particle found outside the nucleus of an atom
- 7. the places surrounding the nucleus of an atom where the electrons are most likely to be at any given time
- 9. An element is a pure substance that is made from a single type of atom. Elements are the building blocks for all the rest of the matter in the world
- 11. a one- or two-letter representation of an element on the periodic table
- 14. a small particle in the nucleus of the atom; it has no electrical charge
- 15. the basic particle from which all elements are made
- 16. the number of protons in the nucleus of an atom; this number identifies an element and its location on the periodic table
Down
- 1. a horizontal row of elements in the periodic table
- 3. a chart of the elements showing the repeating pattern of their properties; arranged by atomic numbers of the elements
- 4. "a class of elements characterized by physical properties that include shininess
- 5. elements in the same vertical column of the periodic table; also known as a 'family'
- 8. the central core of the atom made up of protons and neutrons
- 10. an element that has some characteristics of both metals and nonmetals; these are found hugging the zigzag line on the periodic table
- 12. the average mass of all the isotopes of an element; this is the decimal value found on an element card
- 13. a positively charged particle that is part of an atom's nucleus; the number of protons is known as the atomic number
