Phosphorus has an atomic mass of 31 and an atomic number of 15 the number of neutrons must be?
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
What is the atomic number for an element with 37 neutrons and a mass number of 72?
The mass number is the amount of protons and neutrons in an element. The atomic number is equal to the amount of protons. Therefore to get the number of protons from the given information, you would subtract 37 from 72 which gives you 35 protons aka its atomic number!
Would you use atomic number or mass number or both to obtain the number of particles in an atom?
atomic number is the total number of protons OR electrons in an atom. mass number is the total sum of number of protons and neutrons. atomic number subtracted from mass number gives the number of neutrons in an atom. Mass number - atomic number = number of neutrons.
How many neutrons are in most atomic of iodine if the atomic number is 53 and the atomic weight is 126.9?
Most atomic of iodine has 74 neutrons. The atomic weight of iodine (126.9) represents the combined mass of protons, neutrons, and electrons in the atom. Since the atomic number (53) represents the number of protons in the nucleus, subtracting the atomic number from the atomic weight gives the number of neutrons.
If an element has an atomic number of 45 and an atomic mass of 92 the number of protons it has is?
The atomic number always gives the number of protons or electrons. The neutrons are obtained by subtracting the number of protons from the atomic mass. In this example, since 45 is the atomic number, this element has 45 protons. since the mass is 92, the number of neutrons is 92-45= 47. However, this is not really true because the element with 45 as atomic number is rhodium and it has a mass of 103 u and hence a total of 58 neutrons.
The number of protons plus the number of neutrons gives the atomic?
Mass
If an atom has the atomic number of 4 and the atomic mass of 9.012 how many electrons will it have?
Atomic mass is protons + neutrons, and the atomic number (4) gives you the number of protons. Thus, this atom would have 5 neutrons.
Phosphorus has an atomic mass of 31 and an atomic number of 15 the number of neutrons must be?
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
What does the atomic mass give you the number of?
It gives the number of nucleons = protons + neutrons.
An atom with a mass number of 18 that contains 10 neutrons would have the atomic number of what?
8. Mass number is the number of neutrons plus the number of protons. The number of protons gives the atomic number.
How do you determine the number of neutrons in an isotope if you know the atomic number?
Subtracting the atomic number from the mass number gives the number of neutrons. The atomic number is the number of protons in the nucleus. The mass number is the total number of protons and neutrons in the nucleus and this is the number that is quoted against isotopes, for example fluorine-19 contains 19 protons and neutrons. Fluorine has an atomic number of 9 so it has 10 neutrons.
How are the mass number and the atomic number of an elment different?
The atomic number denotes the number of protons in an atom where the mass number gives the sum of protons and neutrons.
The atomic number gives the number of what in an atomic nucleus?
Atomic Number It is thre position of the atom in the periodic table. It is the number of protons in the neucleud. It is the number of electrons in the neutally charged atoms. Atomic MASS it the total of the protons and neutrons in the atom.
What is the atomic number for an element with 37 neutrons and a mass number of 72?
The mass number is the amount of protons and neutrons in an element. The atomic number is equal to the amount of protons. Therefore to get the number of protons from the given information, you would subtract 37 from 72 which gives you 35 protons aka its atomic number!
What is the number of neutrons protons and electrons in an atom of zirconium 90 that has no overall charge and an atomic number of forty?
Atomic number gives the number of protons: 40. If the atom is neutral, it must have an equal number of protons and electrons. Therefore, the number of electrons is also 40. The isotope number is the same thing as the atomic mass. Atomic mass is basically the sum of protons and neutrons. Therefore, subtracting the number of protons from the atomic mass yields the number of neutrons: (90 - 40 = 50). Thus, there are 50 neutrons.
How many protons does calcium 47 have?
mass number = number of protons + number of neutrons. 47 = 20 + neutrons, so neutrons equal 27.
How do you find the number of neutrons protons and electrons in an atom if the atom is neutral?
The number of electrons in an atom is always equal to the number of protons in that same atom. Since the atomic mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number
