What determins the mass number of nitrogen?
The mass number of a nitrogen atom is determined by the mass of the nucleus. As it is the relative mass, it is equal to the combined number of protons and neutrons in the nucleus of the atom. For example, the most common isotope of nitrogen contains seven protons and seven neutrons, giving it a mass number of 14. Some atoms of nitrogen have an extra neutron, which gives a mass number of 15.
How many electrons if element has mass number of fourteen?
seven
What is the mass number if an atom has 3 protons and 4 neutrons?
seven
What are the atomic number and mass number for the carbon isotope with seven neutrons?
The carbon isotope with seven neutrons is carbon-14. The atomic number of carbon is 6, which represents the number of protons. The mass number is the sum of protons and neutrons, so for carbon-14, it is 6 (protons) + 7 (neutrons) = 14. Thus, carbon-14 has an atomic number of 6 and a mass number of 14.
What is The atomic mass of an element whose atoms consist of seven protons eight neutrons and seven electrons?
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. In this case, the element has 7 protons and 8 neutrons, so the atomic mass would be 7 + 8 = 15 atomic mass units.
What mass number is americium?
The mass number of Am-241 is 241; each isotope has another mass 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.
Can mass be a number?
yes mass can be a number
Nitrogen has 7 protons and 7 neutrons The atomic mass of nitrogen is?
14 A proton has an atomic mass of approximately 1 AMU. A neutron also has an atomic mass of approximately 1 AMU. For most purposes, the atomic mass of an electron is considered to be negligible. Without knowing the number of protons this atom contains, one cannot calculate the atomic mass of the atom.
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
What is the mass number for sodium?
the mass number of sodium is 23
Mass number - atomic number equals?
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
