If a silicon atom contains 16 neutrons what is its mass number?
The mass number is 30.
What is the mass number for a sulfur atom that contains 19 neutrons?
16 protons + 19 neutrons = 35 mass number
What is the mass number for a sulfur atom that contains 31 neutrons?
Each sulfur atom contains 16 protons; the mass number is the sum of the numbers of protons and neutrons; therefore, 47. (It is unlikely that such a heavy isotope of sulfur actually exists.)
An atom contains 70 protons 70 electrons and 99 neutrons What is the mass number?
it is 169
What is the one thing that determines the identity of an atom?
the one thing that gives an atom its identity is the mass number and the atomic number
If a silicon atom contains 16 neutrons what is its mass number?
The mass number is 30.
What part of the atom contains the majority of mass an atom has?
The nucleus contains the mass.
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
A neutral atom contains 12 neutrons and 14 electrons. The mass number and the number of atom are respectively?
The mass number is 26. This is the isotope silicon-26 with the atomic number 14.
What is the mass number for a sulfur atom that contains 19 neutrons?
16 protons + 19 neutrons = 35 mass number
What is the atomic mass of and atom?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What part of the atom contains most of its mass?
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
What is the mass number for a sulfur atom that contains 31 neutrons?
Each sulfur atom contains 16 protons; the mass number is the sum of the numbers of protons and neutrons; therefore, 47. (It is unlikely that such a heavy isotope of sulfur actually exists.)
What is a mass number of an atom that has 12 netrons and 11 protones?
An atom of atomic number 12and mass number 22 contains how many protons?
How would you explain how to determine the number of neutrons and atom contains if you know its mass and its atomic number?
