Protons

Explanation:

I'm not exactly sure if this is what your question, but the number of protons is what makes an atom that atom. If you change the number of proton it is now a different atom. You change the number of electrons and get an ion or change the number of neutrons and get an isotope but you can't change the number of protons as you would be changing the elemnt.

Why do atoms share electrons in covalent bonds?

A. to attain a noble-gas electron configuration

B. to become more polar

C. to become ions and attract each other

D. to increase their atomic numbers​

Answers

Answer:

Answer Option A) To attain a noble-gas electron configuration.

Explanation:

Correct answer from test

Taking into account the definition of covalent bond and octet rule, the correct answer is option A.  Atoms share electrons in covalent bonds to achieve a noble gas electron configuration.

The covalent bond is the chemical bond that occurs between atoms of non-metallic elements. These atoms have many electrons at their outermost level and have a tendency to share them to acquire the stability of the noble gas electronic structure. In this way a molecule is formed.

The tendency of the elements to reach a stable configuration is known as the octet rule. For this, the octet rule explains that there must be eight electrons in their last energy levels, thus acquiring the structure of a noble gas.

So, a covalent bond is a force that joins two atoms of non-metallic elements to form a molecule in order to comply with the octet rule.

Finally, the correct answer is option A.  Atoms share electrons in covalent bonds to achieve a noble gas electron configuration.

Which of the following best describes how Thomson
concluded that electrons are present in all atoms.
a
The charge-to-mass ratio of electrons is always the
same constant, no matter which substances are
used in the cathode ray tube.
b The cathode ray was able to turn a wheel.
The cathode ray always bent toward a negatively
charged plate.
d
The charge-to-mass ratio is unique to each different
element.

Answers

Answer: A

Explanation:

The charge-to-mass ratio of electrons is always the same constant, no matter which substances are used in the cathode ray tube.

Explanation:

Thomson in his model of atom discussed that the atom consists of a negative charge particle termed electron randomly distributed in the positively charged sphere to balance the negative charge.His model of the atom was also known as the Plum pudding model of the atom. In which electrons are embedded in positive soup.He discovered electrons by conducting an experiment with cathode rays in which cathode rays emerging from the cathode were observed to be deflected towards the positively charged plate.He also conducted the same experiment with different metals (for anode and cathode) and gases and found out that the charge to mass ratio of the electron was regardless of the metals or gases used in the experiment.With this, he landed on the conclusion that these particles of cathode rays are the universal component of matter.

So, from this, we can conclude that the charge-to-mass ratio of electrons is always the same constant, no matter which substances are used in the cathode ray tube describes Thomson's conclusion that electrons are present in all atoms.

Answers

Answer:4400

I went over this problem multiple times and I finally found the soultion

The concept of significant figures are mainly used by scientist and engineer to know the significance of digits in a measurement. Therefore, 4400L is the solution to the equation rounded to the correct number of significant figures.

What is significant figures?

Significant figures are the figures that indicate the degree of accuracy of a value. It tells about the precision of a value. It gives an idea about the digits that are necessary to indicate the experimental value.

Rules for counting significant figures are:

Number between 1 to 9 is always significant

Zeroes after a number has got no significance

Zeroes before a number has got no significance

Zeroes between number has got significance

4700 L - 281.4 =4400L

5 units to the left.

Explanation:
They are working against each other. That means you subtract.

32 - 37 = -5

You are moving 5 units to the left because 37 is negative which means it is moving left. The key word is left. In physics, you would get the same answer if you did it this way.

37 - 32 = 5

The 5 moves in the same direction as the 37

Were new substances created form old substances during electrolysis? Explain.

Answers

Electrolysis, process by which electric current is passed through a substance to effect a chemical change. The substance to be transformed may form the electrode, may constitute the solution, or may be dissolved in the solution.

During electrolysis a metal chemically decompose and deposits on the cathode where as the metal from the other electrode forms its ions in the electrolyte solution.

What is electrolysis?

Electrolysis is the process of chemical decomposition brought out by the passage of electricity through an electrolyte in which the decomposed metal deposits on one electrode.

Electrolysis involves oxidation of one metal and reduction of the other. The prediction of the products of electrolysis requires a consideration of several factors including the potential at which the competing species are discharged at the electrode , if the electrode used are reacted or inert etc.

The oxidation reaction involves the formation of cations in the solution and the reduction involves the deposition of metallic substance at the cathode.

.Over a period of 1,000 years, a lake becomes a maple forest. Is this process primary or secondary succession? Explain your answer.

Answers

Answer:

It is secondary succession.

Explanation:

primary succession only occurs in areas where there was no previous ecosystem

In the production of maple forest over the 1,000 years period, there has been the presence of the lake. Thus the production in the lake has been the secondary succession.

The primary and secondary succession has been the development process in the ecosystem. The ecosystem development can be taken place when there has been no previous vegetation, or when there has been the available ecosystem.

The primary succession can result when there has been no available previous ecosystem. The secondary succession can take place when there has been a previously existing ecosystem.
