Atomic Theory Scientists
This subatomic particle has a positive charge.
What is a proton?
Atoms of the same element with different numbers of neutrons.
What is an isotope?
This element has 20 protons.
What is Calcium?
Which has more Energy Red, green or Blue Light?
What is Blue Light
This scientist proposed that electrons orbit the nucleus in fixed paths at fixed energy levels just like planets orbit the sun.
What is Niels Bohr?
This subatomic particle's main contribution to the atom is to give the atom more mass.
What is a neutron?
The atomic number is the same as the number of this particle.
What is a proton?
The electron is in this state when it is energized by light and jumps up to a higher energy level.
What is the excited state?
This scientist described the atom as the smallest, most indestructible piece of matter.
Who is John Dalton?
This subatomic particle gives an atom both its chemical and physical properties.
What is an electron?
Record the hyphen notation of an atom of Oxygen that has 10 neutrons.
What is Oxygen-18?
Why do the weights on the periodic table all end in decimals when you can't split subatomic particles?
What is, the atomic weight is an average of all the Isotopes.
The electron is said to be in this state when it falls back down after releasing energy.
What is the ground state?
This scientist proposed that electrons are located in areas called "clouds" around the nucleus and we can only know the probability of where they are at any given time.
Who is Schrodinger?
These 2 subatomic particles give the atom its mass.
What are protons and neutrons?
This is the formula for mass number.
What is # of protons + # neutrons?
Explain how it is possible to have three different forms of hydrogen.
What is they are isotopes of one another?
In light, Energy level and wavelength have this kind of relationship.
What is Inversely proportional (one goes up the other goes down)
An ancient Greek philosopher who theorized that there must be some particle that is the smallest form of matter and called it "atomos".
Who is Democritus?
This subatomic particle has virtually no mass.
What is an electron?
Magnesium-25 has this number of neutrons.
What is 13 neutrons?
How is ion formed?
Ion is formed when a neutral atom loses or gains electrons
Energy is given off in what form when electrons return to their ground state energy level?
electromagnetic radiation
