The elements in groups 3 - 12.
What are the transition metals?
The most reactive element.
What is Francium?
Elements found in the same group (column) have the same..
The answer, my good sir, is the same PROPERTIES and the same VALENCE ELECTRON NUMBER?
A fluorine atom has 9 protons, 10 neutrons, and 9 electrons. What is the atomic number?
9
What is considered the DNA of the atom? Why?
Protons - they identify the atom. The number of protons equals the atomic number.
Atoms can have different numbers of neutrons, they can gain or lose electrons BUT the number of protons for an element will NEVER change.
The number that tells us the total number of protons plus neutrons at the bottom of each element square on the periodic table.
What is the atomic mass number?
The number of neutrons in this element.

What is zero?
The only metalloid in period 2.
What is Boron?
This element has 32 protons and an atomic mass of 95. How many neutrons will it have?
What is 63 neutrons?
These elements on the periodic table have characteristics of both metals and non-metals.
What are metalloids?
These elements make salts when they combine.
What are Halogens?
What are the elements in group 17 or 7A?
Is this element a metal, metalloid, or nonmetal

Metal
The overall charge of an atom is this.
What is neutral no charge?
What determines the identity of an element.
What is the number of protons or atomic number?
