Almost 75% of the periodic table is made up of these.
What are metals?
This is the name for rows on the periodic table.
What are periods?
This is the ability of a metal to be stretched into thin wires.
What is ductility?
Helium, Xenon, and Neon are examples of this group.
What is a noble gas?
An element that can conduct electricity at high temperatures and insulate at low temperatures.
What is a semiconductor/metalloid?
What element is in period 4, group 15?
What is Arsenic?
I am an insulator at low temperatures. I am brittle and shiny. What am I?
What is a metalloid?
These are often used as building materials and can be brightly colored.
What are transition metals?
Most nonmetals are this state of matter at room temperature.
What is a gas?
Name a non-reactive element that is a gas at room temperature.
What is (any noble gas)?
These are the non-metals in group 17 of the Periodic Table that are most reactive group of nonmetals. They form a -1 ion.
What are halogens?
This is the average mass of the element's isotopes, weighted by the abundance of each isotope.
What is average atomic mass?
Name one metal that is liquid at room temperature.
These elements are semi-conductors meaning they act as conductors at high temperatures and as insulators at lower temperatures.
What is a metalloid?
Name an element that meets the following characteristics: solid at room temperature, halogen, more dense than Bromine.
What is iodine?
This is the scientist who organized the elements in the periodic table by average atomic mass.
Who is Mendeleev?
Name two elements that are in order of atomic number on the periodic table but not in order of average atomic mass.
Many examples.
This is formed when halogens and metals react.
What is a salt?
The most common isotope of this element has zero neutrons.
What is hydrogen?
What atom has 33 protons, 33 electrons, and 40 neutrons?
Arsenic-73
What is the atomic number?
Compare and contrast the following two elements. Give one similarity and two differences.
Potassium (K) and Nickel (Ni)
Both in period 3. Potassium is highly reactive, Nickel is not very reactive. Potassium is an alkali metal, Nickel is a transition element. Metallic properties are similar (shiny, conductor).
I am highly reactive and the least dense metal on the periodic table. What am I?
What is Lithium?
I am highly reactive and good at forming salts with metals. I am a gas at room temperature and have less than 10 protons. What am I?
What is Flourine?
What atom has 34 protons, 36 electrons, 45 neutrons?
Se2-
