The current education question and answer inquired students to express what they presume is the most important element for a student to do if they wanted to accomplish success. Of the many responses, one that that stood out was practice. Successful persons are not always born successful; they become successful thru hard work and determination. This is how you can fulfill your goals. in this article, are one of the answer and question example that you will possibly utilise to practice and further enhance your practical knowledge and also give you insights that may assist you to maintain your study in school.
Give the ion symbol for the the ion that has 15 protons and 18 electrons
The symbol for the ion that has 15 protons and 18 electrons is P³¯
We’ll begin by defining what an ion is.
An ion is an atom or a group of atom with a charge. The charge can be either positive (+) or negative (-) depending on how the ion is formed.
1. The ion will be positive if the element involved loses an electron(s)
2. The ion will be negative if the element involved gained an electron(s).
To solve the question given above, we’ll begin obtaining the symbol of the element. This can be obtained as follow:
From the question given above, we were told that the ion has 15 protons. This (i.e 15 protons) is the atomic number of the element
Now, comparing the atomic number (i.e 15 protons) of the element with those in the periodic table, the element whose ion we are looking for is Phosphorus with a symbol of ‘P’.
Next, we shall determine the charge of the ion. This can be obtained as follow:
Proton = 15
Electron = 18
Charge = Proton – Electron
Charge = 15 – 18
Charge = –3
Finally, we shall determine the symbol of the ion. This is illustrated below:
Charge = –3
Element = Phosphorus
Symbol of element = P
Symbol of ion = P³¯
Therefore, the symbol for the ion that has 15 protons and 18 electrons is P³¯
They would possibly hopefully guide the student solve the question by make use of the questions and answer examples. You will possibly then have a discussion with your classmate and continue the school learning by studying the problem alongside one another.
