Cations are positive so they have less electrons than protons, while anions are negative so they have more electrons.
Vladimir [108]3 years ago
3 0

Answer:

A cation is an atom that has <u>more number of protons than electrons</u> electrons; while an Anion is an atom that has <u>more number of electrons</u> than protons.

Explanation:

A cation is an atom or a molecule which is positively charged, i.e. has more number of protons than electrons, and is attracted to the cathode (negative electrode) during electrolysis

An anion is an atom or a molecule which is negatively charged, i.e. has more number of electrons than protons and is attracted to the anode (positive electrode) in electrolysis.

Because of these characteristic, of being negatively and positively charged, anions and cations usually form bonds. These are known as ionic bonds and exist due to the mutual attraction of oppositely charged ions.

1. What is the scientific method? Is there just one universal scientific method? Why or why
natulia [17]

Answer:

Follows are the solution to this question:

Explanation:

1)

Its scientific process explains how researchers obtain worldwide knowledge. 6 key elements define this method: queries, assumptions, experiments, observations, evaluation, and results. It is interconnected measures, however, that they should not operate in the same sequence often.

2)

It is about learning and describing as just a collective body, Science aims to give an ever more rigorous explanation of the workings of a natural environment, its elements as well as how the country now should be.

3)

Science will help to create the latest knowledge in solving practical problems and determine personally and mutually responsible choices.

4)

Science will allow the intellect to develop new information and also to overcome the excitement on how today's world is developing and functioning. Science was important because it helped to shape the world wherein we live today.

5)

It can write credibility through the use of reliable information to back up your argument in your research. High-quality resources that support your arguments will more frequently lead to better outcomes for the tasks. Its use of reliable sources can help as a topic.

6)

The peer-review will also include subjecting of its author's empirical research and research into another relevance and suitabilities to review by other experts in the same field. Its author should decide if a work is acceptable via a peer review.

7)

Knowledge in which observations are only based on what can be observed directly may help students to learn how science can infer. It can help students to understand why scientists utilize facts in responding to questions by distinguishing among observations and assumptions.

8)

Other components are kept similar by constant. Control systems have such preferential privileges for a single group, whereas the group doesn't seem to.  

9)

In seeing what occurs if you adjust the factor to also be tested you can equate the results of the experimental groups with those of the human rights group. The treatment group is also an integral part of a study because it allows everyone to be removed and separated.

What will happen if you left your plates or tube open to the air for prolonged period of time?
ki77a [65]

Answer:

If the petri plates are kept open for the longer duration of time then there are chances of cross contamination.

The contamination can be defined as growth of undesired microbes in the petri dishes or tubes which is no longer useful for the experiment.

The tube if kept open will develop the growth of contaminants in it. It can be cross contamination as well.

To avoid contamination the tubes and dishes should not be kept open for a longer duration of time.

ankoles [38]

Answer:

This question lacks options, options are:  a. beta-D-fructofuranose b. amylose c. uronic acid d. N- acetylglucosamine. The correct answers are c and d.

Explanation:

Glycosaminoglycans are very long, unbranched polysaccharides, made up of repeating units of disaccharides. One of the disaccharides is always an amino sugar, which can be N- acetylglucosamine. The other is uronic acid (it can be iduronic acid or glucuronic acid and is often sulfated at position 2). The amino sugar is usually sulfated and the rest of the sugars have carboxyl groups, which give the structure a negative charge, which attracts a large amount of cations such as sodium. Glycosaminoglycans are often covalently bound to proteins to form proteoglycans. Hyaluronic acid is the only glycosaminoglycan that does not form protein bonds and does not have sulfate groups in its structure.
