What is the element with the greatest atomic number in period 6?
Radon (Rn)
100
What is the most highly reactive family group?
Family/Group 1
100
What is the only metal that is liquid at room temperature?
Mercury
100
What is the Family/Group that is the most highly reactive group and why?
Family/Group 1 because it has one valence electron and it needs to fill its entire outside shell.
100
What element is non-reactive, has 2 valence electrons and 1 energy level considered to be an inert gas?
What is Helium
200
When determining an elements reactivity, what is the most important subatomic particle?
Valence electrons (the electrons on the outside shell)
200
What determines an elements reactivity and where are they located in an atom?
The number of valence electrons and they are on the outer most electron orbital.
200
Who has 8 valence electrons and has 4 energy levels?
Krypton (Kr)
200
What is the Family/Group that is the most non-reactive and why?
Family/Group #18 because it has 8 valence electrons which gives it a complete outside shell and no room to bond with anything else.
200
What atom is the only non-metal in its family and has 4 valence electrons?
What is Carbon
300
Who out of the following element pairs has the most similar chemical properties? Cl and Ar, Br and Kr, Cl and Kr, Ar and Kr
Ar and Kr
300
What is the element that is the only one in its group to have different properties than its own family, which has properties that conduct electricity and are highly reactive?
Hydrogen because it is in group 1 highly reactive metals and it's not technically a metal itself, but only grouped there for its reactivity.
300
Which statement is correct?
Boron has the same number of valence electrons as Carbon, Nitrogen is larger than Oxygen, Chlorine is more like Bromine
Chlorine is more like Bromine because they have similar chemical properties from being in the same family.
300
When atoms are gaining energy which way are you moving on the periodic table?
What is down the periods gaining energy shells.
300
Which element is the most like Chromium?
Tungsten,
Manganese,
Vanadium
What is Tungsten
400
What is who has the same chemical properties as Sulfur (S) but less atomic mass than Flourine (F)?
Oxygen
400
What group number has a non-reactive Atom with the greatest mass?
Family/group #18 (noble gases) the element of Radon (Rn)
400
Which element in the periodic table is made from reactive metals, has 2 valence electrons and has 20 neutrons?
Calcium (Ca)
400
Explain what happens to the valence electrons when you move to the right on the periodic table?
What is they get larger as you go right.
400
Which member of the Halogen family has 4 atomic orbitals and is the only non-metal to be liquid at room temperature?
What is Bromine
500
What is the element with the most energy and is highly volatile?
Francium (Fr)
500
When determining an atom's reactivity, what part of an atom's structure will you need to analyze?
Outer electron orbital (outer shell)
500
What elements or element is the most lustrous out of, Silicon (Si), Sulfur (S), Chlorine (Cl), Zinc ( Zn)
Zinc (Zn) because it is a metal
500
Who was the first periodic spy to notice the patterns of elements and put them a specific order?
Who is Demitri Mendeleev
500
BE CAREFUL!
Is Antimony or Bismuth most chemically similar to Lead?
What is neither because neither element is in Leads family group.
