If a silicon atom contains 16 neutrons what is its mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, if a silicon atom contains 14 protons (since it is a silicon atom) and 16 neutrons, the mass number would be 14 + 16 = 30.
What is the mass number for a sulfur atom that contains 31 neutrons?
The mass number is calculated by adding together the number of protons and neutrons in an atom. A sulfur atom typically has 16 protons, so if it contains 31 neutrons, the mass number would be 16 (protons) + 31 (neutrons) = 47.
An atom contains 70 protons 70 electrons and 99 neutrons What is the mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, the atom has 70 protons and 99 neutrons, so the mass number would be 70 + 99 = 169.
What is the mass number for a sulfur atom that contains 19 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Since sulfur has 16 protons (its atomic number) and 19 neutrons, the mass number of a sulfur atom with 19 neutrons would be 16 + 19 = 35.
What is the atomic mass number of an atom of sodium that contains 12 neutrons?
The atomic mass number of an atom is the sum of its protons and neutrons. Sodium typically has 11 protons, so if the atom has 12 neutrons, the atomic mass number would be 23 (11 protons + 12 neutrons).
If a silicon atom contains 16 neutrons what is its mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, if a silicon atom contains 14 protons (since it is a silicon atom) and 16 neutrons, the mass number would be 14 + 16 = 30.
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
If the atomic mass of the atom is 48 and it contains 20 protons, then the atom contains 28 neutrons. This can be calculated by subtracting the number of protons from the atomic mass, since the atomic mass includes both protons and neutrons.
What part of the atom contains the majority of mass an atom has?
The nucleus contains the mass.
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.
How many neutrons are present in an atom of a mass 37.8 if it contains 18 protons?
To determine the number of neutrons in an atom, subtract the number of protons from the mass number. The mass number is usually a whole number, so we round 37.8 to 38. With 18 protons, the number of neutrons is 38 - 18 = 20. Therefore, the atom contains 20 neutrons.
What is the mass number for a sulfur atom that contains 31 neutrons?
The mass number is calculated by adding together the number of protons and neutrons in an atom. A sulfur atom typically has 16 protons, so if it contains 31 neutrons, the mass number would be 16 (protons) + 31 (neutrons) = 47.
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.
An atom contains 70 protons 70 electrons and 99 neutrons What is the mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, the atom has 70 protons and 99 neutrons, so the mass number would be 70 + 99 = 169.
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?
What is the atomic mass number of an sodium that contains 12 neutrons?
The atomic mass number of an atom is the sum of its protons and neutrons. Sodium (Na) has an atomic number of 11, meaning it has 11 protons. If it contains 12 neutrons, its atomic mass number would be 11 protons + 12 neutrons = 23. Therefore, the atomic mass number of this sodium atom is 23.
The number of protons and nuetrons in the nucleus of an atom?
The number of protons in the nucleus determines the element's identity, while the sum of protons and neutrons gives the atom's mass number. The nucleus contains nearly all of an atom's mass and is surrounded by a cloud of electrons.
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.
