List two properties of Chromium (atomic # 24).
Two of the following are correct: shiny highly conductive malleable highly reactive
100
How many energy levels would you need to draw for the Bohr model of Barium?
6 energy levels
100
Metals like to _______ their valence electrons and nonmetals like _________ their valence electrons.
Give away (metals) - Take (nonmetals)
200
What particle do we use to identify what type of element an atom is?
Protons
200
The number above the column on the periodic table is the _________ #
Group #
200
Why can't we predict the properties of Boron?
Because it is a metalloid (they have properties of both metals and nonmetals)
200
How many dots (valence electrons) would you draw for the Lewis Dot Structure for Arsenic?
5 dots (valence electrons)
200
Why do metals and nonmetals like to give/take their valence electrons?
They are trying to have a fuller outer energy level (shell).
300
What are the charges of each of the particle in an atom?
Protons are positively charged, Electrons are negatively charged, and neutrons have no charger (neutral)
300
The number along the rows on the periodic table is the ________ #.
Period #
300
Atoms in the same Group all have the same number of ______________________.
valence electrons
300
Draw the Bohr model of Magnesium (atomic #12).
See answer key.
300
metals ions have a ____ (+/-) charge, and nonmetals ions have a ____ (+/-) charge.
400
How many protons and electrons does Bromine (atomic #35) have?
35 protons and 35 electrons
400
The elements on the periodic table go in order by the atom's _________________,
Atomic # (or number of protons)
400
Atoms in the same Period all have the same number of _____________________.
Energy levels (or shells)
400
Draw the Lewis Dot Structure for Silicon (atomic #14).
See answer key.
400
Draw the Lewis Dot Structure for the ion of Rubidium (Atomic # 37) and the ion for Bismuch (atomic #83)
See answer key.
500
How many neutrons does Mercury-201 have?
121 neutrons
500
What do all Group 18 elements have in common?
They all have full outer shells.
500
What happens to the size of atoms as you go down columns on the periodic table?
The atoms get bigger (more protons = more electrons = more energy levels = a bigger atom)
500
Prove that Sulfur is a Group 16 element by drawing the Bohr model and circling the evidence that proves it is indeed a Group 16 element.
See answer key.
