21. When considering the Bohr model of a neon atom, which of the following is a true statement?
Ten protons would be located in the nucleus, and 10 neutrons would be on the outside of the atom orbiting in rings.
Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
O Ten protons would be located in the nucleus, and 20 neutrons would be on the outside of the atom orbiting in rings.
OTwenty protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
The characteristics of the Bohr model allow you to find that the correct answer for the distribution of particles in the atom is:
b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
The bohr model was initially developed for hydrogen, where it manages to fully explain the spectrum of the hydrogen atom, it was quickly spread to other multi-electronic atoms with the characteristic of having a single electron in their last orbit.
The extension to atoms with more than one electron in the last shell the model results are not completely correct.
The Bohr model uses Rutherford's knowledge that the atomic nucleus is a very small part of an atom that contains all its mass, that is, it contains the protons and neutrons and the electrons are in circular orbits around the nucleus.
In the case presented of Neon, its electronic configuration is
1s² 2s² 2p⁶
Let's examine the different claims:
a) False. Protons and neutrons form the mass of the atom, therefore they are both in the nucleus.
b) True. The protons are in the nucleus and the electrons are in circular orbits.
c) False. All protons and neutrons must be in the nucleus, plus neon only has 10 neutrons.
c) False. The number of protons determines the type of atom. An atom with twenty protons is Calcium atom .
In conclusion, using the characteristics of the Bohr model we can find that the correct answer for the distribution of particles in the atom is:
b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.

the following reaction gives a product with the molecular formula c4h8o2. draw the structure of the product.
The following reaction gives a product with the molecular formula C₄H₈O₂. The diagram of the structure of the product can be seen in the image attached below.
The reaction between C₂H₂(ONa)₂ and C₂H₄Br results in the formation of the product C₄H₈O₂ and 2NaBr.
This reaction undergoes an SN₂ mechanism since there is no stable carbocation formed. In the reaction -O⁻Na⁺ attacks the ortho position in C₂H₄Br to form C₄H₈O₂.
In SN₂ mechanism is a nucleophilic substitution reaction where one bond is formed while another one is broken simultaneously.
The mechanism for the reaction can be seen in the image attached below.

Based on electronegativity differences, which bond is a polar covalent bond?
Answer:
A bond in which the electronegativity difference between the atoms is between 0.4 and 1.7 is called a polar covalent bond.
A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal.
why do garden manure and compost fertilize the soil
gardens arent real the government is lying the world is a simulation
As the soil absorbs manure, nutrients are released. This enriches the soil, which in turn helps the plants. The most important benefit of using manure in the garden is its ability to condition the soil For instance, mixing manure with sandy soils helps to retain moisture levels.
During recrystallization, why is it necessary to cool the solution slowly?
answer:
the reason is to ensure more solute is dissolving as it cools down. it is important to do it slowly because water will be sucked into buchner flask by a partial vaccum through the rubber tubing and be able to arrange molecules.

Explain the formation of planets based on our knowledge of the solar system
Planets form from particles in a disk of gas and dust, colliding and sticking together as they orbit the star. The planets nearest to the star tend to be rockier because the star's wind blows away their gases and because they are made of heavier materials attracted by the star's gravity.

A plane travels 450,000 meters in 9000 seconds. What was the plane’s speed?
Answer:
50 metres per second.
Explanation:
Speed is the total distance covered divided by the time taken to cover that distance. Therefore, the plane's speed is obtained by dividing 450,000 metres by 9000 seconds, resulting in a speed of 50m/s.

For the following element, predict the most likely oxidation number (charge) for its corresponding ion.
Phosphorus
A. P+1
B. P+3
C. P-1
D. P-3
The most likely ion of Phosphorous is P³⁻ (group 15) since gaining three electrons is the most energetically favorable way for it to follow the octet rule.
Because the charge on ions is equivalent to their oxidation state, then -3 is the most likely oxidation number of Phosphorous.
