The Atomic Mass of an element is the sum of protons and neutrons in its nucleus. Gallium has an atomic number of 31, which means it has 31 protons. If it has 39 neutrons, then its atomic mass would be 31 (protons) + 39 (neutrons) = 70.
What else can I help you with?
How many neutrons are does yttrium have with an atomic number of 39 and atomic mass of 89?
Yttrium has 50 neutrons. To find the number of neutrons, subtract the atomic number (39) from the atomic mass (89): 89 - 39 = 50 neutrons.
19protons and 20 neutrons are equal to how many atomic mass?
As electrons have such a small mass, they are not counted in the atomic mass. Thus the mass of an atom with 19 protons and 20 neutrons is 39.
What is the atomic mass and neutrons are K?
The mass number of Potassium is 39 which means it has 20 neutrons.
How many neutrons are in an atom of this isotope if the atomic number of yttrium is 39 and the atomic mass of the isotope is 89?
The number of neutrons in an atom can be calculated by subtracting the atomic number (protons) from the atomic mass. In this case, for the isotope of yttrium with an atomic number of 39 and an atomic mass of 89, the number of neutrons is 50 (89 - 39 = 50).
An atoms of potassium has atomic mass of 39 amu and an atomic number it therefore has neutrons in its nulces?
An atom of potassium with an atomic number of 19 has 20 neutrons in its nucleus. This can be determined by subtracting the atomic number from the atomic mass (39 - 19 = 20).
How many neutrons are does yttrium have with an atomic number of 39 and atomic mass of 89?
Yttrium has 50 neutrons. To find the number of neutrons, subtract the atomic number (39) from the atomic mass (89): 89 - 39 = 50 neutrons.
19protons and 20 neutrons are equal to how many atomic mass?
As electrons have such a small mass, they are not counted in the atomic mass. Thus the mass of an atom with 19 protons and 20 neutrons is 39.
How many neutrons does Ga have?
Gallium (Ga) has 39 neutrons.
What is the atomic mass and neutrons are K?
The mass number of Potassium is 39 which means it has 20 neutrons.
How many neutrons are in an atom of this isotope if the atomic number of yttrium is 39 and the atomic mass of the isotope is 89?
The number of neutrons in an atom can be calculated by subtracting the atomic number (protons) from the atomic mass. In this case, for the isotope of yttrium with an atomic number of 39 and an atomic mass of 89, the number of neutrons is 50 (89 - 39 = 50).
How many neutrons does potassium-39 have?
Potassium-39 has 20 neutrons. This is because the atomic number of potassium is 19, which represents the number of protons in its nucleus. Subtracting the atomic number from the atomic mass gives you the number of neutrons.
An atoms of potassium has atomic mass of 39 amu and an atomic number it therefore has neutrons in its nulces?
An atom of potassium with an atomic number of 19 has 20 neutrons in its nucleus. This can be determined by subtracting the atomic number from the atomic mass (39 - 19 = 20).
How many neutrons occur in potassium with a mass number of 39?
Potassium with a mass number of 39 has 20 neutrons. The mass number of an element is the sum of its protons and neutrons. Since the atomic number of potassium is 19 (number of protons), the number of neutrons can be calculated by subtracting the atomic number from the mass number.
How many protons and electrons are in a gallium atom?
Gallium has an atomic number of 31. This means that it contains 31 protons, each one having a +1 charge. Therefore, in order for gallium to have a net charge of 0, it must also contain 31 electrons, because electrons have a charge of -1.
What is the atomic mass of this atom 19p and 20n?
To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. In this case, the atom has 19 protons and 20 neutrons, totaling 39 nucleons. The atomic mass of this atom would be approximately 39 atomic mass units (amu).
What is the mass number and symbol of an atom that contains 19 protons 19 electrons and 20 neutrons?
The mass number is always the sum of the numbers of protons and neutrons and therefore is 39 in this instance. The atomic number of 19 shows that the atom is of the element potassium, and its symbol is 39K.
What is the atomic and mass number of potassium?
The atomic number is 19 and the mass number of its most abundant isotope K-39 is 39 (19 protons + 20 neutrons) while the mass of that isotope is 38.96371 a.m.u.The relative atomic mass of the element potassium, K, is 39.10 g/mole.
