b. protons, electrons and neutrons are evenly distributed throughout the volume of the atom.
c. the nucleus is made of electrons and protons
Answers
Electrons are distributed in shells revolving around the nucleus and occupy almost all the volume of the atom.
In the nucleus of an atom, proton and neutron are present whereas electrons are present in shells revolving around the nucleus. Most of the volume of an atom has empty spaces in which shells are present in which electrons are moving.
The number of protons and electrons are the same in an atom but the number of neutrons are different so we can conclude that electrons are distributed in shells that are present around the nucleus.

As a consequence of the discovery of the nucleus, the model of the atom that is true is A. electrons are distributed around the nucleus and occupy almost all the volume of the atom.
It should be noted that neutron and proton can be found in the nucleus of an atom. Also, there are electrons that are present in the shells that revolve around the nucleus.
In the atom, the number of electrons and protons are the same but there are different neutrons. Lastly, most of the volume of the atom has empty spaces.

The Helium gas tends to behave as an ideal gas at 0temperature and 1 atm pressure.
By applying the real gas law to the gases at the high temperature,m the gases start to behave as the ideal gas.
The gas behaves at the ideal gas when the van der wall force between the gases has been the lowest and they tend to react less with the other atoms.
The Helium gas has the maximum tendency to behave as an ideal gas, as it has been the single atomic gas. Being single atomic, the gas tends to exhibit less forces, and the complete octet helps the gas to reactless with the other atoms.
Because of the characteristics, Helium acts as an ideal gas at STP.
Thus the Helium gas tends to behave as an ideal gas at 0temperature and 1 atm pressure.

The bonds found between water molecules are called:
Hydrogen bonds
which contribute to water having a high number of Van Der Waals forces.
Explanation:
A hydrogen bond is an electromagnetic attraction within polar molecules in which hydrogen is joined to a larger atom, such as oxygen or nitrogen. This is not a dividing of electrons, as in a covalent bond. Preferably, this is an attraction among the positive and negative poles of charged atoms.
Answer:
Hydrogen bonds
