How was Bohr’s atomic model different from rutherfords atomic model
A. Bohr’s model accounted for electrons that have different charges
B. Bohr’s model could explain the structure of the nucleus
C. Bohr’s model showed that electron orbits had distinct radii
D. Bohr’s model could explain the wave nature of electrons
E. Bohr’s model proved that atoms are unstable in the nature
Answers
Answer:
C. Bohr’s model showed that electron orbits had distinct radii
Explanation:
In Rutherford's atomic model, the electrons moved on arbitrary orbits, which was only due to the condition that the Coulomb force acts as a radial force. In Bohr's atomic model, only very specific orbits were allowed, which were determined by Bor's quantum condition.

1. Which family of elements is most likely to lose electrons?
2. Which family of elements is most likely to gain electrons?
Answers
Answer:
Elements that are metals tend to lose electrons and become positively charged ions called cations.
Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions.
Hope it helps:)
Metal are the family of elements which is most likely to lose electrons. Non metals are the family of elements which is most likely to gain electrons.
What is element?The quantity of protons an element has defines it. An element's atoms all contain the same amount of protons, but its electron and neutron counts might vary. Ions are produced by altering the electron to proton ratio, whereas isotopes are produced by altering the neutron count.
118 known elements are present. A study is being done to create element 120.1. The periodic table will have to be modified to include element 120 after it has been created and validated. Metal are the family of elements which is most likely to lose electrons.
Therefore, metal are the family of elements which is most likely to lose electrons.

For a laboratory investigation some students put a strip of shiny metal into a beaker of blue solution and then stored the beaker on a shelf
overnight. The next morning, the students recorded observations about the metal and the solution in the box below.
Students' Observations
Exhibit
. The solution is lighter in color,
The volume of solution is the same.
• The metal strip is shiny above the surface of the solution
• The metal strip is not shiny below the surface of the solution.
• The metal strip below the surface of the solution has a dark
coat of flaky material
• When the metal strip is touched, the flaky material falls off.
Based on their observations, can the students correctly conclude that a chemical reaction occurred?
A. No, because the metal strip was still visible
B. Yes, because a new material of a different color formed on part of the metal strip
c. No, because the solution stayed blue

What is a Chemical reaction?When atoms establish or break chemical bonds, chemical processes take place. Reactants are substances that begin a chemical reaction, while products are the compounds that are created as a result of the reaction. Until the reactants are exhausted, some chemical reactions merely proceed in one direction. It is claimed that these responses are irreversible. Some responses are categorized as reversible. Reactions that are reversible can occur both forward and backward. Reactants change into products in a reversible reaction, but products can also change back into reactants. In actuality, both the forward response and its reverse will occur simultaneously. This oscillation lasts until a particular relative balance between reactants and products is attained a condition known as equilibrium. The forward and backward processes continue to occur at equilibrium, but there is no longer any change in the relative concentrations of products and reactants.

a single cell undergoes mitosis every five minutes how many cells will result from this cell in 20 minutes
Answers
Answer:
= 16 cells
Explanation:
Mitosis is the stage of cell division in nonsexual cells of eukaryotic organisms (that is, cells that have a nucleus). It takes place in several phases, begins after DNA duplication and ends with the separation of the two daughter cells.
It is a fundamental mechanism that occurs for the first time in the hours following fertilization.
After duplication of the genetic material, during interphase, it condenses and groups to form chromosomes with two genetically identical chromatids: this is the prophase. The nuclear membrane then dislocates, and the centromeres of the chromosomes (the area where the two chromatids of the same chromosome overlap) bind to the microtubules via the kinetochores. Gradually, all the chromosomes are sequestered at the equator of the cell: this is the metaphase.
Then, during anaphase, the chromosomes will split into two chromatids, each of which is pulled towards a pole of the cell. Thus, at each top of the cell, there is a copy of each chromosome. During telophase, the nuclear envelope will begin to reform around the set of chromosomes as the DNA gradually decondensed. The plasma membrane invaginates equatorially under the action of a ring of myosin and actin. Increasingly narrow, the bridge between the cells eventually breaks, and two cells are formed as a result of cytodieresis. Each of them can resume their growth.
Now; having understood what Mitosis is all about.
When a single cell undergoes mitosis every 5 minutes; we have the formation of two daughter cells.
Then in 20 minutes; we will have:
= [tex]2^{20/5}[/tex]
= [tex]2^4[/tex]
= 16 cells
Which of the following is an example of an element? a brass b oxygen c rust d water

Answer:
A) Oxygen
Explanation:
An element is defined as something made of only 1 type of atom. Brass and rust are made up of many types of atoms, and water has two types of atoms, hydrogen and oxygen. Oxygen is made up of two oxygen atoms, which are the same element. So, by definition, oxygen is an element.

The central C is also attached by 1 line to a C, which is attached to 2 H's and a C by a single line each. The C is attached by 2 lines to an O ad by 1 line to another O. The O with 1 line is attached by 1 line to an H. What is the chemical formula for the molecule modeled? CHO C4H11O2 C6H12O2 C6H9O
Answers
Answer:
C6H12O2
Explanation:
The first step in accurately deducing the structure/formula of the model is to count the number of carbon atoms, hydrogen atoms and oxygen atoms mentioned in the model. This gives the molecular formula of the compound.
Next, you look at there arrangement of atoms and bonds as stated in the model, this tells us the structure of the molecule and confirms the molecular formula initially deduced.
The structure of the compound is shown below.
Answer:
Your answer would be C6H12O2

Answers
Lead
Explanation:
by emission of alpha particles
The end product of the decay of uranium 238 is Pb-206.
Heavy elements are generally grouped into four decay series which are; Thorium series, Uranium series and actinium series and Neptunium series.
These heavy elements decay via a series of α and β emissions until a stable nucleus is finally achieved. All these decay series usually terminate in a lead nucleus.
Uranium 238 belongs to the uranium decay series and terminates at Pb-206.
