J. j. thomson studied cathode ray particles (electrons) and was able to measure the mass/charge ratio. his results showed that?

Answers

Answer 1

His results showed that matter included particles much smaller than the atom.

J. J. Tomson concluded that atoms are divisible and that the corpuscles are their building blocks.

Atoms are made up of smaller particles.

J. J. Thomson discovered the electron ( the negative charges of the atom) in 1897.

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge and evenly distributed throughout the entire atom.

With this model, he abandoned his earlier hypothesis that the atom was composed of immaterial vortices.

Later, scientist Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate.

Error in Measurement can be defined as difference in value between the actual value and the measured value.

There are some factors that might have contribute to the inaccuracy in the measurement of the metal block and they include :

faulty measuring tool or instrument

The students may have have used a faulty instrument or an inaccurate instrument. The accuracy of the measurement will depend on the kind of scale they used. A kitchen scale, for example, is probably less accurate than a calibrated scale in a chemistry lab.

random error by the students

Random errors occurs when there might have been an error due to inability to read the accurate value of the instrument.

not accounting for temperature changes

Density varies with temperature and their might have been slight changes in temperature leading to inaccuracy in the readings.

Which statement about Niels Bohr's atomic model is true?

Answers

Correct answer is Each orbit has a specific energy level.

According to Bohr's atomic model There is a certain energy for each orbit, with the inner orbit having the lowest energy. As you move farther from the nucleus, the energy of the orbits increases. We can say that the energy of the electrons are quantized if we state that they can only have certain energies.The ground state, also known as the lowest orbit, is where the electron typically resides.A lower energy level to a higher energy level is reached by an atom's electrons by gaining the necessary energy, and a higher energy level to a lower energy level by losing energy.Inner energy levels have low energy and outer or higher energy levels have high energy.

One type of chemical reaction is combustion. Carbon dioxide is produced when carbon combines with oxygen in the combustion of charcoal, for example. Carbon and oxygen are reactants, or the chemicals that initiate a chemical reaction. The process produces carbon dioxide. However, this change is just physical.

What is Density?

Density may be defined as a type of physical property that significantly deals with the description of how much space an object or substance takes up with respect to the amount of matter in that object or substance.

In a more simple sense, it is characterized as the measurement of quantity or mass per unit of volume in a particular substance.

According to the question,

The density of iron chloride solution = 1.118 g/mL.

The mass of iron chloride solution = 1.75 kg.= 1750 g.

The formula for calculating the density is as follows:

Density = mass/volumeVolume = mass/density.

Volume = 1750 g/1.118g/mL = 1565.29 mL.

If two atoms are joined by a polar covalent bond, the shared electrons will tend to stay closer to the atom with the higher electronegativity

What is electronegativity?

An atom's ability to attract the electrons of a bond is known as its electronegativity, and it rises as this propensity does. A covalent bond is formed when two coupled atoms with the same electronegativity values are in close proximity to one another.

In a chemical bond, the more electronegative atom often attracts the electrons more than the other atom. A polar covalent bond is the result of this. The electrons are not at all shared if the electronegativity values are drastically different. To create an ionic bond, one atom effectively accepts the bond electrons from the other atom.
