Week 3 - Matter (Part 2)

Introduction to Matter

Learning Target: I will explore how atoms are organized within the periodic table.

Warm-Up (8/25/20)

  • What element has the symbol Te?
  • What is the symbol for Cerium?
  • What element has a mass number of 73?
  • Please add this link to the DYNAMIC PERIODIC TABLE OF ELEMENTS to your bookmarks.

Vocabulary Word Wall

Matter - anything that has mass and takes up space

Mass - in physics, the quantity of matter

Atom - the smallest unit of an element that maintains the chemical properties of that element

Element - a substance whose atoms all have the same number of protons

Substance - matter which has a specific composition and specific properties

Subatomic - smaller than or occurring within an atom

Nucleus - In physical science, an atom's central region, which is made up of protons and neutrons

Proton - a subatomic particle that has a positive charge and is located in the nucleus of an atom

Neutron - a subatomic particle that has no charge and that is located in the nucleus of an atom

Electron - a subatomic particle that has a negative charge

Atomic Number - the number of protons in the nucleus

Mass Number - the sum of the numbers of protons and neutrons in the nucleus of an atom

Isotope - two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei so they have a different mass number

Electron cloud - ​the region of negative charge surrounding an atomic nucleus where there is a high probability of locating the electrons

Ion - an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge

Molecule - two or more elements joined together by a bond

Properties - traits that can be measured (like the amount of mass)

Period - a horizontal row on the periodic table

Group or Family - a vertical column of the periodic table

Reactivity - the tendency of a substance to undergo a chemical reaction

Bohr Model Activity

Students will begin the following project this week:

  • Draw and label a Bohr model of any element you choose on the Periodic Table of elements.
  • Each part of the model must be labeled and color coded and you will add a key (like a map).
  • You may draw this by hand or draw it in a digital program. You must share it with me once it is completed.
  • The model must have all of the following to be complete:
1) Your name on it2) Protons (correct number and charge)3) Neutrons (correct number)4) A Nucleus5) Electrons (correct number and charge)6) Electron locations (circles around the nucleus)7) 10 Facts about that particular element8) A color coded key to each part of the model
