The smallest part of anything; made up of protons, neutrons, and electrons
What is an atom?
100
The elements in the periodic table are organized into families based on this.
What are chemical properties?
100
The periodic table is arranged in this way (from one row to the next).
What are increasing atomic numbers (by one each time)?
100
This number gives us the numbers of electrons and protons in the element.
What is the atomic number?
100
Elements that have the same numbers of protons but different numbers of neutrons.
What is an isotope?
200
A particle inside the nucleus that has no charge
What is the neutron?
200
This family is referred to as "happy" because they have a filled outer energy level.
What are the inert (noble) gases?
200
How many groups are located on the periodic table?
What are 18?
200
Lithium has an atomic number of 3, how many protons and electrons does it have?
What is 3?
200
This family is full of good conductors.
What are metals?
300
A particle inside the nucleus that has a positive charge
What is a proton?
300
This family takes up the entire middle of the periodic table, accounting for about 75% of the elements
What are metals?
300
How many periods are there on the periodic table?
What are seven?
300
Aluminum has an atomic number of 13 and an atomic mass of 26.982. How many protons, neutrons, and electrons does it have?
What are 13 protons, 14 neutrons, and 13 electrons?
300
At this time, this is the maximum number of electron orbitals that any element may have.
What is seven?
400
The particle outside of the nucleus, in orbits
What is an electron?
400
This is the name of the family located in group 1, with the exception of Hydrogren.
What are the alkali metals?
400
This is the information we can learn from each group (column) in the periodic table.
What is the number of valence electrons?
400
Xenon has an atomic number of 54 with an atomic mass of 131.29. How many protons, neutrons, and electrons does it have?
What are 54 protons, 77 neutrons, and 54 electrons?
400
This is a characteristic of many elements, that fall in between conductors and insulators. Due to changes in temperature and/or the amount of energy added, the electrons can begin to move and conduct electricity.
What is a semi-conductor?
500
These two parts make up the nucleus of the atom.
What is a proton and a neutron?
500
This family is located off of the bottom of the periodic table and all elements are radioactive with most not being found naturally on earth
What is the actinide family?
500
This is the type of information we can learn from each period (row) of the periodic table.
What is the number of orbitals?
500
Describe how to find the number of neutrons in an element.
What is 1) find the atomic mass 2) either round it up or keep it the same, 3) then subtract the atomic number from the atomic mass, 4) this answer is the number of neutrons.
500
This gentleman created the first periodic table, by arranging elements according to similar properties.
