What is a reasonable value for the atomic mass of the missing element in the periodic table?
The atomic mass of an element is found on the periodic table. It is the weighted average mass of all the isotopes of that element. Without more information, it's not possible to provide a specific value for the missing element's atomic mass.
To find the number of neutrons in an atom you would subtract what?
You would subtract the atomic number from the mass number.
If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element?
You would need to know the abundance of each isotope to find the average atomic mass of the element. The average atomic mass is calculated by multiplying the mass of each isotope by its relative abundance and then summing these values together.
If an element has 3 isotopes with known masses what other information is needed to find the average atomic mass of the element?
The abundance of each isotope is needed to find the average atomic mass of the element. The average atomic mass is calculated by multiplying the mass of each isotope by its abundance, summing those values, and then dividing by 100 to get the average atomic mass in atomic mass units.
If an element has three isotopes with known natural abundance percentages what kind of information is needed to find the average atomic mass of the element?
To find the average atomic mass of the element, you would need the mass of each isotope and their corresponding natural abundance percentages. Multiply the mass of each isotope by its respective abundance percentage, then sum these values for all isotopes to determine the average atomic mass of the element.
How do you find the atomic mass by adding what?
Atomic mass = Mass of protons + Mass of neutrons
How many neutrons are in an isotope of lithium if it has an atomic mass of ten?
An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.
How does the atomic mass help you find the neutrons?
Atomic mass = mass of protons + mass of neutrons.
What information does atomic mass give you?
Atomic mass is the average mass of all isotopes of a given element.
If you had the mass number and the atomic number what would you do to find the number of neutrons?
it is find it ur selfs!!
How do you get the atomic mass of lithium?
To find the atomic mass of lithium, you would look at the periodic table and find the atomic number for lithium, which is 3. The atomic mass is typically located directly below the element symbol, which for lithium is around 6.94 grams per mole.
If an element has 3 isotopes with known natural abundance percentages what other information is needed to find the average atomic mass of the element?
You still need to know the number of protons present in order to find the atomic mass.
