What is the formula to calculate the area of a square?
The formula can be written, with "n" representing a number or value, as n2 or n X n.
What does the atomic mass tell us?
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
What is the formula to calculate complication and infection rate?
the number of complications in a certain period divided by the total number of patients for the same period
What is the formula for percent compostion?
A/B=X/100. A=number you are trying to calculate, B=amount which you are calculating it from, X= percentage
In Microsoft Excel how do you use a formula to calculate the percentage of use of a set of symbols?
In A1, put the total number of symbols.In B1, put the number of symbols used.In C1, enter the formula =A1/B1Format C1 for percent and observe the answer.
What is a nuclide symbol?
A nuclide symbol represents a specific isotope of an element and consists of the element's chemical symbol, atomic number, and mass number. The chemical symbol is a one- or two-letter abbreviation for an element, the atomic number is the number of protons in the nucleus, and the mass number is the sum of protons and neutrons in the nucleus.
How do you calculate the number of nuetrons fo an atom?
You cannot calculate but you can guess mostly by its atomic number. Studies shows that while carbon atoms mostly have 6, some are 5 or 7.
How do you find the mass number of a nuclide?
The mass number of a nuclide is found by adding together the number of protons and neutrons in the nucleus of the atom. It is represented by the symbol A in the nuclide symbol.
What information must be known in order to calculate the mass number if an atom?
The mass number = the number of protons + the number of nuetrons. Each of these particles is considered to have a mass of 1 amu. (atomic mass unit) For example, Aluminum has 13 protons and 14 nuetrons, so it's mass number = 27.
What is the mass number of carbon-12 nuclide?
12. When a nuclide is (properly) named in the form [element name]-[number], the number is always the mass number.
A nuclide is identified by?
A nuclide is identified by the number of protons in its nucleus, known as the atomic number, and the total number of protons and neutrons, known as the mass number. These two properties determine the unique identity of a specific nuclide.
What is nuclide writing?
Nuclide writing is a notation system used to represent a specific nuclide of an element. It includes the chemical symbol, atomic number, and mass number of the nuclide. This notation is helpful for identifying different isotopes of an element.
How do you determine the number of protons in a nuclide?
The number of protons in a nuclide is determined by its atomic number, which is unique to each element. The atomic number is typically listed in the periodic table and represents the number of protons in the nucleus of an atom.
How do you calculate the amount of protons or neutrons in an element?
To calculate the number of protons in an element, you look at its atomic number on the periodic table. The number of neutrons can be calculated by subtracting the atomic number from the element's atomic mass number.
What is the number of nuetrons in potassium?
20
What number represents the protons and nuetrons?
The mass number
What is a correct representation for a nuclide of radon?
A correct representation for a nuclide of radon in atomic symbol notation would be ^22286 Rn. This indicates that the nuclide has 222 nucleons (sum of protons and neutrons) and an atomic number of 86 (number of protons).
