Atoms
True or False: Atoms are the basic building block of matter
True
Alkali Metals
What are the vertical columns on the periodic table called?
Groups or Families
What is an ion?
An atom that has a charge (Either positive or negative)
What are isotopes?
Atoms that are of the same element, but have different number of neutrons (since the atomic mass number is made up of protons and neutrons, isotopes also have a different mass number)
Positive
What is the name of group 8A on the periodic table?
Noble Gases
What are the horizontal rows on the periodic table called?
Periods
What is a cation?
An ion with a positive charge
This element has 16 protons and 18 neutrons. What is the name of the element? Double points bonus: What is the new mass of this element?
Sulfur (S). The new mass is 38.
What charge do neutrons have?
None or Neutral
What is the name of group 7A on the periodic table?
Halogens
Valence electrons
What is an anion?
An ion with a negative charge
This element has 19 protons and 19 neutrons. What is the name of the element? Double points bonus: What is the new mass of this element?
Potassium (K). 38.
What particles are located within the nucleus?
Protons and Neutrons
What is the name of group 2 on the periodic table?
Alkali Earth Metals
What are the 3 main regions of the periodic table?
Metals, metalloids, and nonmetals
What is the ionic charge for Oxygen (O)
-2 as it is in group 6 and contains 6 valence electrons. Remember, with ions you are adding electrons to make the valence electrons 8 or taking away electrons to make the valence electrons equal 0.
Using Fluorine (F, group 7A) on the periodic table, how many neutrons would Fluorine-20 have? Remember: round the mass from the periodic table up to the nearest whole number.
11. (Fluorine on the periodic table has a mass of 19, which results in 10 neutrons, so therefore a Fluorine with the mass of 20 would have 1 more neutron at 11)
What particles make up the Atomic Mass Number?
Protons and Neutrons
Groups 3A-2B are known as what?
Transition metals
What two elements are liquid at room temperature?
Mercury (Hg) and Bromine (Br)
What is the ionic charge for sodium (Na)?
+1. Na is in group 1 so it has 1 valence electron, so we remove the valence electron to take it to 0 valence electrons.
Using Magnesium (Mg, Group 2A) from the periodic table, how many neutrons would Magnesium-32 have?
20. Magnesium on the Periodic table has a mass of 24 and 12 protons. 24-12=12 neutrons. Since the mass has been increased from 24 to 32, then we must have added 8 neutrons to account for the mass difference.
