To put this as straight forward as possible, Rutherford came up with the nuclear model of the atom, before that, no one knew that the nucleus even existed, people use to think that most of the atom was made up of positive charge overall, with some negative (electrons) charge on the top of it, this theory was called the Plum pudding.

Rutherford disproved this theory, and came up with his own model, which would contain the nucleus, in this there's a tiny positively charged nucleus at the centre, surrounded by a cloud of negative electrons .

Bohr modified the atom structure even more, he realised that electrons in a cloud around the nucleus of an atom, as Rutherford described would quickly spiral down into the nucleus, causing the atom to collapse. So Bohr proposed a new model of the atom with basic principals:

-Electrons only exist in fixed orbitals (shells) and not anywhere in between.
-Each shell has a fixed energy

Rutherford explained the nucleus of an atom, while Bohr was more into the electrons and their energy levels.

hope that helps

Answer from: chasechevy13

In the Rutherford model, electrons can exist in any location outside the nucleus.

In the Bohr model, electrons can exist only in certain energy levels surrounding the atom.

Answer from: Quest

the balanced equation for reaction of ca metal with o2 to produce cao is as below

2 ca+ o2→ 2 cao2

explanation

the reaction is balanced since the number of atoms in reactant side is equal to number of atoms in product side. for example they are 2 atom of ca in reactant side and 2 atoms of ca in the product side.

the process is a meet the requirement of redox reaction because : calcium is oxidized from oxidation state 0 to 2+ while oxygen is reduced from oxidation state 0 to 2-

Answer from: Quest

They can measure the amount of energy gained or lost

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
