What is mass,charge, and location in the atom
100
Who organized the elements by increasing atomic mass?
What is Dmitri Mendeleev

What are valence electrons?
What is the electrons in the outer energy level of an atom.
100
What do elements in the same family have the same of?
What is the same number of valence electrons
200
What was Dalton's atomic theory?
What is all atoms of a given element were exactly alike, and atoms of different elements could join to form compounds.
200
How can you tell how many protons are in an element?
What is the atomic number of the element is the same as the number of protons
200
Who arranged the modern day periodic table by atomic number?
What is Henry Moseley
200
What is an ion?
What is a charged atom that has gained or lost electrons.
200
What are the five families of the periodic table in order?
What is alkali Metals, Alkaline-Earth metals, transition metals, halogens, noble gases
300
What is Rutherford's Model of the Atom?
What is Rutherford proposed that most of the mass of the atom was concentrated at the atom’s center - nucleus.
300
How do you find the number of neutrons in an element?
What is mass number minus the atomic number
300
What does each element on the periodic table include?
What is the average atomic mass, atomic number, the symbol, and the name
300
What is a metalloid?
What is elements that touch the stair stepper.
300
Are Alkali metals or Alkaline-Earth metals more reactive?
What is Alkali metals
400
What is the modern atomic model?
What is In the modern atomic model, electrons can be found only in certain energy levels, not between levels - the location of electrons cannot be predicted precisely.

What is the SI base unit used to measure the amount of a substance whose number of particles is the same as the number of atoms of carbon in exactly 12 g of carbon-12
400
Do elements become more or less metallic across each period?
What is they become more metallic
400

What is the periodic law?
What is the law that states that the repeating chemical and physical properties of elements change periodically with the atomic numbers of the element
