What particle was Bohr primarily concerned with when developing his model of the atom

The electron

100

Name the 3 particles that make up the atom

Protons, electrons, neutrons

100

The scientist who gets credit for the "billiard ball model" - where he said an atom was like a tiny ball that could not be split

Dalton

200

CuTe

What is Copper and Tellurium?

200

How many protons are in the nucleus of an Argon atom?

18

200

Draw the Bohr model for Sulfur

Sulfur is in the 3rd row of the periodic table and has 16 electrons. This means its Bohr model will have 2 full energy levels, and a 3rd energy level with 6 electrons in it.

200

Where are electrons located in an atom?

in orbitals / shells around the outside
200

Who discovered the electron?

JJ Thompson

300

GeNiUS

What is Germanium, Nickel, Uranium, Sulfur.

300

How many neutrons does an atom of Hydrogen have in its nucleus?

Zero

300

Draw the Bohr model for Calcium

Calcium is in the 4th row of the periodic table and has 20 electrons. These electrons are dispersed among 4 energy levels. The first 3 are full, with 2, 8, and 8 electrons in each level respectively. The 4th energy level has 2 electrons in it.

Where in the atom can we find the protons and neutrons

The nucleus

Which model of the atom featured electrons embedded evenly within a positively charged sphere

Thompson's "Plum-pudding" model

400

PoWEr

What is Polonium, Tungsten and Erbium?

400

What is the mass number of Chlorine? (rounded to a whole number)

35

400

How many electrons can the 2nd energy level hold in Bohr's model?

8 electrons

400

An atom of Zinc (Zn) has 30 protons, 30 electrons, and 35 neutrons. What is its overall charge and WHY?

NEUTRAL, because there is an equal amount of positives (protons) and negatives (electrons) so they cancel each other out. The neutrons have no charge so it doesn't matter how many there are.

Rutherford is known for discovering a certain region of the atom by bombarding sheets of gold foil with positively charged particles. What region did he discover?

The nucleus

500

BaNKrUPtCY

Barium, Nitrogen, Krypton, Uranium, Platinum, Carbon, Yttrium


500

What does the atomic number tell you about it's corresponding element? 

The number of protons in 1 atom of that element

500

What did Bohr say about the nature of the energy levels in his models? Could electrons be found in between the energy levels?

Electrons could be found only within the definded energy levels, not in between them. Therefore, his energy level are referred to as being quantized.

500

What is the most fundamental difference between atoms of two different elements?

The number of protons in the nucleus of the atom

500

Rutherford discovered the nucleus with his gold foil experiment. What else was Rutherford able to determine about the nature of the atom by conducting this experiment. (Hint, how big or small did he determine the nucleus to be)

The fact that a large majority of the particles went straight through the sheet showed that most of the atom is composed of empty space and that the nucleus was a very small region of the atom.
