1 PERIODIC TABLE
2 PERIODIC TABLE A visual representation used in Science to organize the elements according to their chemical and physical properties When talking about the Periodic Table, you will hear words like: Group Family Period Valence electrons Energy levels
3 Group or Family PERIODIC TABLE All the elements in a single column on the periodic table are said to be in the same group or family. All elements in the same group/family have similar chemical characteristics This is because they have the same number of valence electrons Valence electrons: the number of electrons in the outer most orbit of an element
4 Group or Family PERIODIC TABLE You will see that on the Periodic Table they are numbered (IA, IIA, IIB, etc) Each group/family also has a name (we ll come back to this in a bit)
5 PERIODIC TABLE Period (orbits, energy levels, energy shells) All the elements in a single row on the periodic table are said to be in the same period All elements in the same period have the same number of electron shells (orbits)
6 Groups (same number of valence electrons)
7 Periods (same number of shells)
8 Staircase PERIODIC TABLE You ll also notice that there is a staircase along part of the Periodic Table This staircase divides the metals from the non-metals Most elements along the staircase are metalloids
9 Non-metals Metalloids Metals
10 A NOTE ON HYDROGEN Hydrogen You ll notice that hydrogen is labelled as a non-metal even though it is placed on the side with the metals; this is because it does not exhibit most of the characteristics required to be a metal (we ll discuss these shortly) But sometimes it does act like a metal For our purposes, it is a non-metal!
11 PROPERTIES OF METALS, NON-METALS AND METALLOIDS Metals: Left of the staircase Metallic lustre Good heat conductors Good electrical conductors Malleable Ductile Very reactive when placed in water and acid High melting point All solid at room temperature (except mercury)
12
13 PROPERTIES OF METALS, NON-METALS AND METALLOIDS Non-Metals: Right of the staircase Opposite properties of metals: No metallic lustre Do not conduct heat or electricity well Not malleable Not ductile Do not react violently with acids or water Can be solid, liquid or gas at room temperature
14 PROPERTIES OF METALS, NON-METALS AND METALLOIDS Metalloids: Along the staircase Exhibit some characteristics of metals AND some of non-metals Ex: shiny (like a metal) but not malleable (like a non-metal)
15 GROUP NAMES & CHARACTERISTICS
16 GROUP NAMES & CHARACTERISTICS Alkali metals First group on the left (does not include hydrogen remember, not a metal) The most reactive family Because each element only has one valence electron Obviously, have all the properties of metals
17 GROUP NAMES & CHARACTERISTICS Alkaline earth metals Second group from the left (starts with Beryllium) Very reactive but not as much as alkali metals Again, have all the properties of metals
18 GROUP NAMES & CHARACTERISTICS Transition metals All the metals in the middle chunk of the Periodic Table You re not responsible for them!
19 GROUP NAMES & CHARACTERISTICS Groups 3A, 4A, 5A and 6A Just named after the first element in the group Ex: Boron family, Carbon family, etc FYI: They don t usually ask you about these on the exam
20 GROUP NAMES & CHARACTERISTICS Halogens Group 7A (begins with Fluorine) Have all the characteristics of non-metals If you mix a halogen with a metal, you ll get a salt Halogen + metal = salt Used as disinfectants/antiseptics Kills bacteria, fungi, etc That s why people use chlorine to keep their pools from growing algae!
21 GROUP NAMES & CHARACTERISTICS Noble or Inert Gases Produce a bright light when electricity is passed through them Think neon signs All of their electron shells are full This means that these elements are fully stable they do not react chemically with any other substance Will NOT form compounds
22 PRACTICE
23 PRACTICE QUESTIONS 1) Fill in the table below. Element Br Ca Na He Number of valence electrons Chemical family name 7 ve- Halogen 2 ve- Alkaline earth metal 1 ve- Alkali metal 2 ve- Inert gas
24 PRACTICE QUESTIONS 2) Four elements from the periodic table are described below: Be Na Ca Si Element 1: This element from Period 2 has two more electrons than helium Element 2: This soft metal from Period 3 has one valence electron. Element 3: This element from Period 4 is found in bones and teeth Element 4: This element from Period 3 has some of the properties of metals and non-metals Which of these elements belong to the same group or chemical family? A)1 and 2 B)1 and 3 C)2 and 4 D)3 and 4
