What was Lavoisier's discovery about mass not being able to be made or destroyed?
Law of Conservation of Mass. The the number of the compound or elements in the reactant is equal to the product.
How do you find the mass number of an element?
The formula for mass number is number of neutrons = mass number - atomic number. Mass number can also be referred to as nucleon number.
What is the mass number for the element uranium?
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238
How can you get the mass number and atomic number of element?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why do you subtract the atomic number from the mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
The sum of the protons and the neutrons will tell the atomic what?
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
What is the different between mass number and atomic number?
Atomic number is the number of protons within the nucleus of the element. Mass number is the total mass of the element (made from number of electrons, protons, and neutrons). You can calculate the approximate mass of the element by multiplying the respective mass of each component by its corresponding amount. However, there will be a discrepancy by the calculated amount and the real amount because some of the mass is converted into energy when the element is formed.
Is this statement correct atoms are made up of nucleus and electrons composed of protons whose number is called the atomic number and neutrons whose numbers added together make the mass number?
It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
What year was the hr gardner mass model 732 made?
Need the serial number.
What was Lavoisier's discovery about mass not being able to be made or destroyed?
Law of Conservation of Mass. The the number of the compound or elements in the reactant is equal to the product.
Can mass be a number?
yes mass can be a number
In order to calculate the number of neutrons you must subtract the from the?
Number of neutrons = Mass number - atomic number
How do you find the mass number of an element?
The formula for mass number is number of neutrons = mass number - atomic number. Mass number can also be referred to as nucleon number.
How do you find the number of neutrons from the mass number?
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
What is the mass number for the element uranium?
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238
