The positive particle in the nucleus
What is a proton

What does reactive mean?
When something explodes, catches fire, has the ability to react and change into a new substance
100
Elements located to the right of the zig zag ladder
What is non metals
100
The rows that go across are called...
Periods

What's more important in determining the identity of an atom in a Bohr Model? Protons, Neutrons, or Electrons?
Protons
200
The neutral particle in the nucleus
What is a neutron
200
What two groups are very reactive?
Groups 1 and 17
200
Elements located along the zig zag ladder
What is metalloids
200
The Columns that go up and down are called what?
Groups
200
Name an element that is similar to Arsenic (As) but has a lower atomic mass
Phosphorus or Nitrogen
300
The negative particle located outside the nucleus
What is an electron
300
What group is not reactive at all?
What is group 18 (party poopers, noble gasses)
300
The atomic number tells us what about an atom?
How many protons it has
300
The Period # tells us what about an atom?
How many energy shells/rings it has
300
Whats the atomic mass of an atom that has 17 Protons and 20 Neutrons?
The mass would be about 37. You have to add them together
400
The electrons located on the final shell
What is a valence electron
400
The term for something non-reactive
What is Inert
400
Larger atomic numbers are located on the left or right side of the periodic table?
Right
400
What does the group number tell us about an atom?
The number of valence electrons an atom has
400
whats the electrical charge of an atom that has 4 protons, 5 Neutrons, and 4 Electrons? +4 -4 +5 -5
+4
500
Where the electrons are located
What is the electron cloud, energy shells, or energy rings
500
The particle that determines reactivity
What is valence electrons
500
Which has a bigger, heavier atom? Potassium (K), a metal? Or Krypton (Kr), a gas?
Kr
500
Do groups or periods determine an atoms reactivity?
Groups, duhhhhh
500
Explain why Neon is non reactive
The atom has no more room on its outside shell for valence electrons, so i cannot reactive with any other atoms. Making it Inert
