The electron cloud model uses the basic idea of Bohr's model, representing the atom as if it were cut in half. The difference is that Bohr's model showed electrons in "shells" which modeled that they moved only in a distinct orbit around the nucleus. The modern model has layers of electrons, but models the concept that they form a cloud where their exact position is impossible to known (considering is changes). The modern model explains that electrons are not at a fixed distance from the nucleus, but the Bohr model does not represent this understanding, instead, it displays a concept that the electrons are at fixed levels of orbit.

Answer:

According to modern model of atom that is the electron cloud atom, the electrons are found in orbitals. Orbitals are the region where there is probability to find an electron in an atom. According to Bohr's model, electrons revolve around the nucleus in fixed energy shells.

Electron cloud model explains that the position of electron cannot be found exactly. It can be found in a region. The repeating nature of chemical properties of atoms in periodic table can be explained by both the models.

Answer:

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

Explanation:

<em>The correct option would be that the average kinetic energy of the gas particles is greater in container B because it has a higher temperature.</em>

<u>According to the kinetic theory of matter, the temperate of a substance is a measure of the average kinetic energy of the molecules of substance. In other words, the higher the temperature of a substance, the higher the average kinetic energy of the molecules of the substance.</u>

In the illustration, the gas in container B showed a higher temperature than that of container A as indicated on the thermometer, it thus means that the average kinetic energy of the molecules of gas B is higher than those of gas A.

An object has a mass of 72 kg. What is its weight?
In-s [12.5K]

Answer:Acceleration due to gravity on the moon is 1/6 times as that on the earth and we know that mass is property of the material it always remains same and weight is measure of gravitational force, hence

mass of object on moon is 60kg and weight =60g/6=10×10=100N

If enough changes occur in the gene pool of a species, it is possible that a new species would be created.
lianna [129]

Answer:

Yes

Explanation:

A gene pool is the sum total of all the genes(sum of alleles)of a species and population at any given time is known as gene pool.

The new species are created in nature by four mechanisms such as geographic isolation (allopatric speciation), reproductive isolation (sympatric speciation), mating behaviour (parapatric speciation).

Due to any of these factors when population acquire unique changes in their genes and enough changes have been introduced in the gene pool of the population with time, two population become distinct from each other and not able to interbreed leads to the formation of new species.

8. Write a balanced chemical equation showing how you could prepare each of the following salts from an
polet [3.4K]

Answer:

according to my reading

use own words

Explanation:

Salts are combinations of acids and bases. The cation comes from a base and the anion from an acid. Therefore, to make KNO3 we react KOH and HNO3. See how that is done? We write K and add OH to make KOH. We take NO3 and add H to make HNO3.
