What is the mass number of an atom of tin that has 70 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Since tin has an atomic number of 50 (which corresponds to the number of protons), an atom of tin with 70 neutrons would have a mass number of 120 (50 protons + 70 neutrons).
What atom has an atomic number of 56 and a mass number of 137 amu?
Barium has an atomic number of 56 and a mass number of 137 amu
How many neutrons are in a neutral atom of calcium with a mass number of 41?
A neutral atom of calcium with a mass number of 41 would have 20 protons since calcium has an atomic number of 20. To find the number of neutrons, you subtract the atomic number from the mass number, so there would be 21 neutrons in this atom.
What is the mass number of a sulfur atom with 17 neutrons?
S with 17 neutrons and 16 protons has a mass number of 33 amu
If an atom has a mass of 23 amu does that mean it has an odd number of protons?
Not necessarily. The mass of an atom is determined by the sum of its protons and neutrons. An atom with a mass of 23 amu could have an even or odd number of protons, depending on the specific element.
What is the mass of an atom with 13 protons and 14 neutrons?
The mass of an atom is primarily determined by the sum of its protons and neutrons. To find the mass of an atom with 13 protons and 14 neutrons, add the total number of protons and neutrons together: 13 protons + 14 neutrons = 27. The approximate mass of this atom would be 27 atomic mass units (amu).
What is the weight of the atom if an atom has 9 protons?
The weight (mass) of an atom with 9 protons will vary depending on the number of neutrons. 9 protons defines the atom as fluorine (F), and it can have 10 protons, making the mass 19 amu, or it can have a mass of 14 amu up to 31 amu, but the only stable isotope is the one with a weight (atomic mass) of 19 amu.
What is the atomic mass of a atom?
The atomic mass of an atom is the total mass of protons, neutrons, and electrons in the atom, measured in atomic mass units (amu). It is approximately equal to the sum of the number of protons and neutrons in the atom's nucleus.
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
What comprises the atomic mass?
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. It is approximately equal to the mass number of the atom, which is the total number of protons and neutrons. The atomic mass is typically expressed in atomic mass units (amu).
How many neutrons are there in a zinc Zn atom with a mass number of 66?
A zinc atom with a mass number of 66 has 34 neutrons. This is determined by subtracting the atomic number (number of protons) from the mass number, since the mass number represents the sum of protons and neutrons.
Which 2 parts in an atom have the same mass?
Protons and neutrons have approximately the same mass in an atom. Protons have a mass of about 1 atomic mass unit (amu), while neutrons have a slightly larger mass of about 1 amu.
