This is the center of an atom.
What is the nucleus?
The number the red arrow is pointing to in this picture.
What is the atomic mass?
The type of element that is generally shiny, solid at room temperature, conductive, and malleable.
What is metal?
The element with 47 protons.
What is silver (Ag)?
These particles have a negative charge, no mass and located outside the nucleus.
What are electrons?
This increases as you go down and to the left of the Periodic Table.
What is atomic mass (or atomic number)?
The type of element generally found on the right side of the Periodic Table.
What is nonmetal?
The element represented by this picture.
What is magnesium (Mg)?
These two particles (found in the nucleus) are what makes up an atom's mass
What are protons and neutrons?
An element with very similar properties to potassium.
Sodium (Na) or Rubidium (Rb)
We call elements that often give, take, or share electrons this name.
The group number and element(s) with a full outer shell that contains 2 electrons.
The atomic number of an element tells me the number of this in the nucleus
What are protons?
These correspond to the period number of an atom in the Periodic Table.
What are energy levels/shells?
The most reactive type of element (metal, metalloid, or nonmetal).
What is metal?
The element with four energy levels and two valence electrons.
What is calcium (Ca)?
The charge of an atom with 5 protons and 3 electons.
What is +2?
What are valence/outer shell electrons?
The most reactive metal out of chlorine (Cl), iron (Fe), sodium (Na), and hydrogen (H).
What is sodium (Na)?
The more reactive element.
