If an element has a mass number of 208 and an atomic number of 83 how many neutrons does the element have?
To determine the number of neutrons, subtract the atomic number from the mass number. In this case, 208 - 83 = 125 neutrons.
How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
To determine the number of neutrons in an atom, what must be done?
To determine the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the atom). Neutrons are particles found in the nucleus of an atom and carry no charge.
What is the neutron and proton responsible for in an atom?
Protons make up the identity of the element and give it its unique properties. Protons have a positive charge. Neutrons give an atom additional mass, and the number of neutrons in an atom make it an isotope of an element. Neutrons have no charge.
Finding the number of neutrons in an element?
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the mass number (sum of protons and neutrons). Neutrons do not carry a charge and help stabilize the nucleus of an atom.
What and what make up 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. Protons have a positive charge and neutrons have no charge, contributing to the overall mass of the atom. The number of electrons, which have a negligible mass, is not included in the atomic mass.
How do you find the number of neutrons when an element has a charge?
Neutrons are neutrally charged. It is not possible to determine the charge of an atom through knowledge of the number of neutrons contained within its nucleus. Consider hydrogen, for example. It has no neutrons, one proton, and one electron. Its charge is neutral. Deuterium is hydrogen with a neutron, but also has the same charge. Tritium is hydrogen with two neutrons within its nucleus--again, no charge.
What is the mass number of potassium-40?
0 is the charge of the isotope because it has 19 electrons and 19 protons but 20 neutrons. Even if the number of neutrons changes it has no effect on the charge of the atom so 19- and 19+ leads to a neutral or no charge. 0 is the answer
What are the element number of neutrons?
Number of Neutrons = Mass number - Number of Protons
Are neutrons the same as mass numbers?
No. The number of neutrons is represented by the element's atomic number, not the mass number.
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
How do you find the number of neutrons in a element using only mass and the element name?
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the element). The atomic number can be determined from the element's position on the periodic table.
An isotope of an element with a relative atomic mass of 65 amu and 35 neutrons has a charge of 2 plus How many electrons does it have?
An isotope with 35 neutrons and a charge of 2+ means it has 33 electrons (atomic number - charge). The atomic number can be calculated by subtracting the number of neutrons (mass number) from the relative atomic mass, so in this case, the atomic number is 30 (65 - 35).
What makes an atoms mass number?
An atom's mass number is determined by the sum of its protons and neutrons. Protons have a positive charge and determine the element's identity, while neutrons help stabilize the nucleus and contribute to the atom's mass.
If an element has a mass number of 208 and an atomic number of 83 how many neutrons does the element have?
To determine the number of neutrons, subtract the atomic number from the mass number. In this case, 208 - 83 = 125 neutrons.
What is the number of neutrons for a specific element equal to?
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
