100
The subatomic particle that makes up the electron cloud
What is an electron?
100
the number of protons in the nucleus of an atom; used to determine an element's position in the Periodic Table
What is the atomic number?
100
What does APE in APE MAN stand for?
Atomic # = # of protons= # electrons
100
The mass of a proton and an electron are the same.
TRUE OR FALSE if false what is the correct answer.
False.
Protons and Neutrons both have a mass of 1 AMU.
100
What element am I if tWO energy levels and SEVEN valence electrons.
F or Fluorine
200

300
This part of the table tells you how many energy shells
What is rows or Periods?
300
What subgroup is your green? 
What is a metal?
300

20
300
What element is this?
What is Boron?
400
Full outer ring and not very reactive
What is a stable atom?
400
This part of the table tells you the similar properties and reactivity of the atom
What are columns or groups?
400
What subgroup is your orange?
Non metals
400
How many protons, neutrons, and electrons are in a Bromine (Br) atom?
Protons-35, Electrons-35 Atomic Number: 35, Neutrons: 45
Mass Number: 79,904 is rounded to 80.
Neutrons: Mass number-atomic number=45
80-35=45
400
Balanced
