This part of an atom is the center of the atom and contains two atomic particles in it.
What is nucleus
100
I am an atomic particle with a positive charge that lives in the nucleus of an atom.
What is proton
100
I am a negatively charged atomic particle that lives in the electron cloud.
What is electron
100
I am one way the periodic table is arranged. I am in order and I can tell you how many protons and electrons an element has.
What is atomic number
100
What side of the periodic table are metals found on?
What is right
200
I surround the nucleus and have one atomic particle that lives in me.
What is electron cloud
200
I am a negatively charged particle that lives in the electron cloud of an atom.
What is electron
200
My atomic number is 46, I have 46 protons, BUT I only have 32 neutrons. How many electrons do I have?
What is 46
200
I am one way the periodic table is arranged. I run horizontally across the table and I tell you how many energy levels are in the electron cloud.
What is periods
200
I have properties of both metals and nonmetals.
What is metalloids
300
Atomic Number = ???? = Electrons
What is protons
300
I am a neutral particle that lives in the nucleus of an atom.
What is neutron
300
I can only have a maximum of 2 electrons in my energy level. I also have the least amount of energy out of all the other electrons. What energy level am I?
What is closest to nucleus
300
I am one way the periodic table is arranged. I run vertically and I tell you that the elements in my column have similar properties.
What is groups
300
I am in the outermost energy level of the electron cloud and I am responsible for bonding with other elements.
What is valence electrons
400
What is the formula for finding the number of neutrons in an atom?
What is Atomic Mass - Atomic Number
400
