100
Group 15
What are 5 valence electrons.
100
Has the most mass but take up the least amount of space.
What is the nucleus.
100
A change in the electron configuration creates these between two or more atoms.
What is a chemical bond.
100
Helium and Hydrogen have only one electron shell so they are found in this period.
What is 1
200
This unique family of elements has the most elements of all the families of the periodic table at 38 elements.
What are the transition metals?
200
Elements that will most likely lose valence electrons are the _________ elements.
What are the metal
200
The electrons are found in this location.
What is the electron cloud?
200
Atoms that gain or lose electrons and become ions create this bond.
What is an ionic chemical bond.
200
There are 7 of them and they tell you how many occupied electron shells there are.
What are periods?
300
These elements do not conduct heat or electricity and can appear in all 3 phases of matter. Most of them are gaseous or brittle solids.
What are the non-metals?
300
Atoms lose valence electrons while other atoms gain valence electrons to create this chemical bond.
What is an ionic chemical bond?
300
Atomic mass describes the total number of these.
What are protons and neutrons.
300
Atoms that alternately fill and unfill their outer electron shell so that it is full have this type of chemical bond.
What is a covalent chemical bond.
300
Periods are useful in determining the structure of...
What are atoms?
400
These elements are known as the most stable of all the elements on the periodic table.
What are the noble gases?
400
The typical number of valence electrons needed to make an element chemically stable and non reactive.
What is 8
400
These have a positive charge and determine the identity of each element on the periodic table as they represent the atomic number of the element.
What are protons.
400
A nonmetal and nonmetal atom make this.
What is an covalent chemical bond
400
The actinide and lanthanide series of elements all fall in group 3 on the periodic table. This means that they have 3 valence electrons in their outer shell. They fall in periods 6 and 7 which means they
What is have either 6 or 7 electron shells.
500
This family of elements are synthetic which means they are man made in a lab.
What are the Rare Earth Metals or Transuranic Elements.
500
Groups 8, 9, and 10 have this number of valence electrons.
What is 8
