Electrons can exist only in certain allowed discrete energy states/ Photon absorption and emission are the result of transitions between energy states/ Electrons with more energy have orbits further from the nucleus

True or false The Bohr model of the atom could be correctly applied to only one atom the helium atom?
Niels Bohr in fact based his model on the hydrogen atom. However, I wouldn't say that the Bohr Model can be correctly applied to ANY atom. Whilst it is an excellent approximation it is not truly accurate. Please don't forget that the Bohr Model is just that, a model, and a model is never as accurate as the real thing.
The currently accepted model of the atom includes an electron cloud.?
True
What was the discovery about the nucleus from Rutherford?
It is true that an atom has a nucleus. As for which model of the atom is thought to be true, at the present time we use a model based upon quantum mechanics which differs significantly from the early Rutherford or Bohr atomic models.
Why are heavy atoms are not appreciably larger than the hydrogen atom?
My theory to why heavy atoms are not appreciably larger than the hydrogen atom is supposedly because that gases can expand and so that hydrogen is a gas, it is larger though if hydrogen were compressed, it should grow appreciably smaller than heavy atoms. Also to make that test fair you would have to make the heavy atom at its gas state so that then you could see the true, fair differ in size between a hydrogen and heavy atom.
Is it possible 2 lose an atom sweating?
When people sweat, they lose water through their skin pores. For the fact that water consists of hydrogen and oxygen atoms, it is true that someone can lose an atom from sweating.

Bohr preformed his experiments with the hydrogen atom?
Yes, its true. Therefore every theory developed by Bohr is based on Hydrogen atom.
Which statemment is not true of most cellular redox reactions?
A hydrogen atom is transferred to the atom that loses an electron.
The lighter the atom the less mass in one mole of that atom?
Correct, because if there are fewer protons and neutrons in an atom, it will have a lower mass.
Is it true that amphipathic molecules are molecules that do not contain any hydrogen atom?
No, that is not true. They are molecules that have both hydrophobic and hydrophilic parts.
Is it True or False that water consists of an atom of oxygen that has formed a covalent bond with two atoms of hydrogen?
True. H2O
How is a hydrogen bond created?
A hydrogen bond is the electromagnetic attractive interaction of a hydrogen atom and an electronegative atom, such as nitrogen, oxygen or fluorine, that comes from another molecule or chemical group. It is not a true chemical bond. The hydrogen atom has an attraction to another electronegative atom. These attractions can occur between molecules (intermolecularly), or within different parts of a single molecule (intramolecularly)
True or false since the 1930s the model of the atom has changed a great deal?
true it has .
The currently accepted model of the atom includes an electron cloud.?
True
According to the Plum Pudding Model electrons are distributed randomly throughout the positively charged pudding of the atom?
The current model of the atom states that electrons travel as waves in the electron cloud that surrounds the nucleus. This model was proven by Louis de Broglie.
