Subatomic particles
The three types of subatomic particles.
What are protons, neutrons and electrons?
Dalton believed atoms were like these.
What are billiard Balls (small and indivisible)
The electron dot structure for Calcium would have this many dots representing Valence Electrons.
2
This family is the most reactive on the periodic table.
What are the alkali metals?
This number often found at the bottom of a periodic table square and that can be used to find the number of neutrons in an atom.
What is the atomic mass number?
The negatively charged subatomic particle.
What is an electron?
Thomson believed atoms were like these.
What is Chocolate chip ice cream, plum pudding, or chocolate chip cookie (subatomic particles)
The electron dot diagram for Sulfur would have this many dots representing valence electrons.
6
This family is known for having full valence shells.
What are the Noble Gases?
The abbreviated form of the element name.
What is the chemical symbol?
What is a proton?
Rutherford thought atoms looked like these.
What is a cherry with a pit (nucleus)
The electron dot diagram for Arsenic would have this many dots representing valence electrons.
5
This group of elements is found on the stair step divide between metals and non metals
What are the Metalloids?
This number reveals the number of protons and electrons an element has.
What is the atomic number?
What is a neutron?
Bohr thought the atom looked like this.
What is the solar system (electron orbit)
The electron dot diagram for Potassium would have this many dots representing valence electrons.
1
These elements are found in group 2 of the periodic table.
What are the alkaline earth metals?
This is the word used for horizontal rows on the periodic table.
Where each of the subatomic particles are found.
What is the electron cloud (electrons) and the nucleus (protons and neutrons)?
The current model says that an atom looks like this.
What is A cotton ball (dense middle with electrons somewhere in the outer material)
The electron dot diagram for Helium would have this many dots representing valence electrons.
2
These elements are found in group 17 of the periodic table.
What are the halogens?
This is the word used for vertical columns on the periodic table.
What are groups?
