20 Points The smallest particle into which an element can be divided and still be the same substance. The meaning of it’s name is “not able to be divided”. What is an atom?

40 Points Positively charged particle located in the nucleus of the atom. What is a proton?

60 Points Negatively charged particle of the atom surrounding the nucleus. What is an electron?

80 Points Particle located in the nucleus of the atom with no charge. What is a neutron?

100 Points A dense, positively charged area of the atom. What is the nucleus?

120 Points An atom that has the same number of protons but different numbers of neutrons? What is an isotope?

100 Points The weighted average of the masses of all the naturally occurring isotopes of an atom. What is the atomic mass?

120 Points The force that holds the protons together in the nucleus of an atom. What is strong force?

20 Points Something that occurs or repeats at regular intervals. What is periodic?

40 Points The chart that lists all the elements arranged by atomic number and set-up in patterns that repeat What is The Periodic Table of Elements?

60 Points Elements that are directly on the zig-zag line or close to it and have properties of both metals and nonmetals, sometimes they are called semiconductors. What are metalloids?

80 Points Group one on the periodic table with one electron in it’s outer energy level and very reactive. (Lithium and Sodium are examples) What are alkali metals?

100 Points Group two on the periodic table…has two electrons in the outer energy level and is reactive. (Beryllium and Calcium are examples) What are alkaline-earth metals?

120 Points Second to the last group on the periodic table…group 17…very reactive. (Chlorine and Flourine are examples) What are halogens?

20 Points A vertical column on the periodic table What is a group or family?
