Physical Science Semester 1 Short Answer Concepts
Steps of the scientific method
Graphing-be able to graph and find a slope (I give you slope) know what goes on the x & y axis
Metric conversions: K H D U D C M
Given a group of elements with the same atomic # but different masses, explain why they can
have different masses but MUST have the same atomic #
5) What do Electron Dot Diagrams show us?
6) What can we store highly reactive elements in and why?
7) Give the electron configurations of three elements.
8) Complete a chart with symbols, protons, neutrons, & mass & isotopic symbol
a. Mass # = protons + neutrons (Neutrons = Mass # - Protons)
b. Isotope Symbol includes the element symbol w/ the mass # in the upper left corner, the
atomic # in the bottom left corner, and the charge in the upper right (if there is one)
9) Given a group of elements, be able to tell the following about them:
a. # of energy levels (the periodic # it’s in)
b. # of valance electrons (Column #s 1A-8A)
c. If it’s a metal, nonmetal, or metalloid (colored periodic table)
d. If a bond is ionic (metal + nonmetal) or covalent (2 metals)
10) Draw several dot diagrams (each dot represents a valance electron around the element symbol)
11) Draw how electrons will move to form ions then determine the chemical formula.
12) Determine the ionic chemical formula given a pair of elements.
