In his experiment, Rutherford concluded that atoms have a nucleus because

some of the particles were deflected back towards the alpha source.

most of the particles went straight through the foil.

some of the particles were deflected near the front of the screen.

not enough information is given.

which explanation of this notation is correct?

6 tells you there are 6 protons

6 tells you there are 6 neutrons

What do these isotopes of carbon all have in common?

protons, atomic number, and mass number

Which statement is INCORRECT use of mole measurement?

two moles of CaCl 2 is equal to 6.02 x 10 23 molecules

one mole of calcium is 40.01 grams.

one mole of calcium is equals to 6.02 x 10 23 atoms

two moles of KI is equals to 166g

When compared, a mole of oxygen and a mole of sulfur, how many atoms each has?

both contains 6.02 x 10 23 atoms

sulfur has 32.06 grams of atoms

What's a valence electron?

electrons in the outermost energy level

electrons in the second energy level

When can atoms emit photons?

When an electron is going from the excited state to the ground state

When the electron is in the ground state

When the electron is in the excited state

When an electron is going from the ground state to the excited state

What is happening in the picture

An atom is emitting a photon to go to a lower state

An atom is absorbing energy to go to a higher state

Why did the alpha particle (positively charged particle) sometimes bounce back when hitting the gold foil.

hit proton in nucleus and they repelled alpha particle

hit neutron in nucleus and they repelled alpha particle

hit electrons in electron shells and they repelled alpha particle

What did Bohr add to the model of the atom?

electrons found in specific orbits around nucleus

What electron configuration matches an oxygen atom?

1s 2 2s 2 2p 6 3s2, 3p 6 4s 2 3d 10 4p 5

Which of the following is a characteristic property of ionic compounds?

They form hard, brittle crystals with characteristic shapes

They contain no charged particles

Which of the following describes covalent bonds?

Bonds form to fill outer electron shells

Bonds form because of opposite charges

Electrons are transferred between atoms

If an atom has no charge, which of the following must be true?
