What are 4 properties of metals?
Ductility, malleability, luster, and conductivity.
Name a Metalloid
Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, Polonium
Which specific group is Neon found in?
Noble Gas: Group 18
30 (M-A=N; 55-25=30)
What is the one nonmetal in group 14
Carbon
What element is in group 8, period 5?
Ruthenium
Which group of elements is between the metals and nonmetals?
Metalloids
What element is in group 16, period 6?
Polonium
Which would be more reactive, Francium or Potassium? How do you know?
Francium because as you move down the periods, the elements become more reactive.
How many neutrons are in Mercury?
121 (M-A=N)
What group is the element Barium found in (metals, non-metals, metalloids)?
Metals
Which element would have more in common with Gold: Copper or Lead and why?
Copper because elements in the same group share chemical properties.
What is the atomic number of Fermium?
100
Which atomic number would not go with an inert element? 2, 10, 18, 37, 54, 86, 118
37
True or False: Nobel gases are the most reactive because they are in group 18.
False
What is the chemical symbol for Copper?
Cu
Which would be more reactive, element 21 Scandium or element 26 Iron? How do you know?
Scandium: as you move towards the outside of the table (towards groups 1 and 17) elements get more reactive.
Which element would be more dense? Element 77 Iridium or Element 35 Borine? How do you know?
Iridium because it is on the left with the metals and metals are more dense.
Which would be an insulator? Element 19 Potassium or Element 86 Radon?
Element 86 Radon because it is on the right with the non-metals and non-metals are insulators.
Which element would be a semi-conductor and why? Lithium, Sulfur, or Antimony
Antimony because it's in the staircase with the metalloids, and metalloids are semi-conductors
How many electrons would a neutral atom of Scandium have?
21
Name an element that has the same number of electron shells as element 11 Sodium?
Either: Magnesium, Aluminum, Silicon, Phosphorus, Sulfur, Chlorine, or Argon (anything in period 3)
Name an element with 10 valence electrons?
Any element in group 10: nickel, palladium, platinum, dermstadtium
How many electron shells does Xenon have?
5 because it is in period 5
How many valence electrons does Germanium (element 32) have?
4 because it's in group 14
