In order to calculate the number of neutrons you must subtract the from the?
Number of neutrons = Mass number - atomic number
The mass number of an element is the number of?
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
Can you use the mass number of an element to determine the number of electrons in an atom?
Mass number = number of protons + number of neutrons Number of electrons = number of protons = mass number of an isotope - number of neutrons
What is the mass number of a atom?
the mass number is number of protons in an atom, plus the number of neutrons.
What is the mass number of deterium?
The mass number of deuterium is 2
How many protons neutrons and electrons in 40Ca plus 2?
I don't want to do your homework for you. Here's how you figure it out: Protons = atomic number Neutrons = atomic mass - atomic number Electrons = atomic number + ionization
What is electronic configuration of 40CA?
2-8-8-2
What is the isotope of calcium?
Calcium has at least six stable natural occurring isotopes, and three radioactive ones: Ca-41, 45, 47.The stable ones are (mass)numbered: 40, 42, 44, 46 and 48, plus the only odd one 43.
What is an element called when it has same mass number and different atomic number?
Answer: (A series of) isobars.An example of a series of isobars would be 40S, 40Cl, 40Ar, 40K, and 40Ca (atom numbers from 16 to 20).The nuclei of these elements all contain 40 nucleons, however they contain varying numbers of protons and neutrons. They are all (particular isotopes of) different elements.Atomic number is tied to the number of protons an element has. Each element has a different number.The mass number is the sum of the number of protons AND neutrons of a particular isotope of an element.(The total mass is the avarage mass of all naturally occurring isotopes, thus including protons, neutrons, and electrons of those atoms)Example:Elements with atom number 6 (Carbon) and atom number 7 (Nitrogen) both have isotopes with mass number 14.C-14 (6 protons with 8 neutrons) weights 14.00324 a.m.u. andN-14 (7 protons with 7 neutrons) weights 14.00307 a.m.u.
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
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.
Why is the atomic mass number not a whole 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.
