100
Where is the atomic number found on the periodic table?
In the upper portion of each element's box above the symbol
100
What group of atoms on the periodic table are most reactive? Give both name and number.
Group 1, alkali metals
100
What do we call an atom that has gained or lost electrons?
An ion
100
What are the three states of matter represented on the table?
Solid Liquid Gas
200
Where are all the subatomic parts located?
Proton - in the nucleus Neutron - in the nucleus Electron - orbiting the nucleus
200
What are the horizontal rows on the periodic table called?
Periods
200
Why is Dmitri Mendeleev important to our studies?
He created the original periodic table and organized it by atomic mass.
200
What is a negative ion and a positive ion called? (must name both)
negative - anion positive - cation
200
What are the only liquids on the chart?
Mercury Bromine
300
What are the charges of the subatomic particles?
Proton - positive charge Neutron - neutral (no charge) Electron - negative charge
300
What do the horizontal rows tell us?
The row number tells us how many energy levels of electrons each element has
300
Why is Neils Bohr important to our studies?
He created the Bohr Model of the atom that shows the energy levels for the electrons.
300
What do we call an ion that has gained or lost neutrons?
An isotope
300
What three things do protons and neutrons have in common?
1. size 2. found in nucleus 3. make up the atomic mass/weight
400
Where are valence electrons located?
the last or outermost energy level orbiting the nucleus
400
What do we call the columns in the periodic chart (both names)?
Group and family
400
What group on the periodic table is not reactive? Give name and number.
Group 8/18, Noble Gases
400
What does the atomic number tell us?
The number of protons in one atom of an element.
400
What determines the charge of an atom?
The number of protons and electrons
500
What particle determine the type of atom?
The proton
500
What do elements in the same group have in common?
They all have the same number of valence electrons.
500
Why is Group 18 non-reactive?
The valence shells of the noble gases is already full so it doesn't want to give away or take any electrons.
500
What takes up the most space in the atom?
The electron cloud
