Atoms
The charge of a proton
Positive
The total number of protons & neutrons in the nucleus determines this in an atom
Atomic mass
A sodium atom (Na) bonds with a chlorine atom (Cl)
Ionic Bond
Alkali metals
The scientist credited with creating the Periodic Table
Mendeleev
The charge of a neutron
Neutral / No charge
The number of protons of an atom determines this
Atomic number or Element
The "staircase"
Metalloids
The correct Bohr shorthand for Oxygen (O)
O(2,16)
The charge of an electron
Negative
The number of protons in an atom of Na (sodium)
11
A copper (Cu) atom bonds with a zinc (Zn) atom
Metallic bond
The columns of the Periodic Table
Groups/Families
Where the transition metals are located
Groups 3-12
The overall charge of an atom
Neutral / Equal number of positive & negative
***DAILY DOUBLE***
The number of neutrons in an atom of Na (sodium)
12
This bond occurs between a metal and non-metal
Ionic
The rows on the Periodic Table
Periods
Electrons in the outer-most energy shell of an atom
Valence electrons
Isotopes of an element differ in the number of these
Number of neutrons
23
This bond occurs between two non-metals
Covalent
TRUE or FALSE: Elements in the same group/family have the same number of valence electrons.
TRUE
The reason it is important to know valence electrons
Shows tendency to bond with other elements
