An element has the following Electron Configuration 1s^2 2s^2 2p^2.
What is Carbon? (To form this electron configuration, you stop at the end of each orbital in each period and write out the configuration for that last element in the orbital; you do this over and over until you reach the element you are looking for.)
100
An Element that has 5 Protons.
What is Boron? (The proton # and atomic # are the same, so just look for 5 on the periodic table to get Boron.)
What is a family? (Every group has a family, multiple groups can make up one family as well.)
200
As we go right on the periodic table, atomic radii decreases. As we go down the periodic table, atomic radii increases.
What is the trend of atomic radii? (As more valence electrons are added going to the right, there is more pull from the nucleus causing the radii to decrease going right. As we go down, the sheer amount of electrons added causes the radii to increase going down.)
200
The first person to come up with the concept of atomic theory.
What is Democritus? (Democritus is the first person known to have came up with anything like the atomic theory.)
200
S^-2 has an electron configuration of _______________.
What is 1s^2 2s^2 2p^6 3s^2 3p^6? (Because the element has a negative charge of 2, you can tell that is has 2 more electrons than it has protons; that is why it is 3p^6 instead of 3p^4.)

Silicon is an example of a _________, because it contains traits of Metals and Nonmetals.
What is Metalloid?
300
The rows that are in the periodic table.
What is a period?
300
The energy required to remove an electron.
What is ionization energy?
300
An atom that is positively or negatively charged.
What is an ion?
300
The outermost electron in an atom.
What is Valence Electron?
300
Copper is in the ______ metal group.
What is transition? (Groups 3-12 are mainly all transition metals.)
400
S, P, D, and F.
What is an orbital? (There are only 4 orbitals in which electrons are present in an atom.)
400
Increases as we go from left to right. Decreases as we go from top to bottom. Similar to ionization energy and has the same trend.
What is electronegativity? (The nonmetals want to gain electrons therefore they have a higher electronegativity; they are in the top right corner so the trend of increasing electronegativity from left to right and decreasing from top to bottom is only fitting.)
400
Has 45 protons and 46 electrons.

What is Rhodium -1? (The -1 is attached because the atom is negatively charged by one as there is one more electron than there are protons.)
400
The most active Elements have __ and __ Valence Electrons.
What is seven and one? (The reason these groups are the most reactive, is because they are the closest to having 8 valence electrons, therefore they react a lot more in order to gain or lose electrons to make 8.)
400
Calcium is an example of a(n) __________.
What is Alkali Earth Metal? (Group 2 are all Alkali Earth Metals.)
What is Yttrium? (To form this electron configuration, you stop at the end of each orbital in each period and write out the configuration for that last element in the orbital; you do this over and over until you reach the element you are looking for.)
500
Typically want to lose electrons to get 8 valence electrons.
What is Metal Trend? (Most metals have 4 or less valence electrons, so they'd rather lose some to make 8 than to gain some valence electrons.)
500
Has 112 Protons and 173 neutrons, the element and atomic mass is...
What is Ununbium and 285? (To find the element, you just go to the element with an atomic number of 112. To find the atomic mass you can either look on the periodic table, or add the protons to the neutrons.)
500
The element with 86 protons would have an electron dot diagram that looks like ___.
What is Rn with 8 dots around it? (To find Rn, we look at the 86 protons; to figure out how many dots there are, you need to know how many valence electrons the element has.)
500
The only metal that is a liquid at room temperature on the periodic table is _____.
What is Mercury? (Mercury is shown as blue on the periodic table, meaning that it is liquid at room temperature.)
