An element's atomic mass does not include the mass of its?
An element's atomic mass does not include the mass of its electrons. Electrons have such a small mass compared to protons and neutrons that they are not typically included in calculations of atomic mass.
What is The atomic mass of an element is equal to?
The number of protons, electrons, and neutrons:P
Why mass of electrons is excluded from atomic mass?
The mass of electrons is not excluded from atomic mass. The mass number of an isotope of an element excludes electrons because it is the sum of protons and neutrons.From Wikipedia, "The atomic mass (ma) is the mass of a specific isotope, most often expressed in unified atomic mass units. The atomic mass is the total mass of protons, neutrons and electrons in a single atom."
What is the mass of an ion with 107 electrons?
The mass of an ion with 107 electrons would depend on the specific element of the ion. You would need to know the atomic number of the element to calculate the mass accurately using the atomic mass of the element.
What element in the periodic table has atomic mass of 230 with 86 electrons?
Rn has 86 electrons, Th is the closest to having an atomic mass of 230
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
An element's atomic mass does not include the mass of its?
An element's atomic mass does not include the mass of its electrons. Electrons have such a small mass compared to protons and neutrons that they are not typically included in calculations of atomic mass.
What is The atomic mass of an element is equal to?
The number of protons, electrons, and neutrons:P
What is this element atomic mass?
mass of protons + mass of neutrons present in the element (as the mass of electrons is practically negligible)
How are atomic mass and atomic number different?
Atomic number is the number of protons in the nuclei of the atoms of an element. Atomic number is unique to each element. Atomic Mass is the combined mass of the protons, neutrons, and electrons in an atom of an element.
How many electrons and protons are in an element with an atomic?
put it in your mind! The Atomic number. is number of protons, While The Mass number. is number of protons and electrons. when you subtract both get the number of electrons and this for any element but not all elements have same atomic numbers or mass and Rutherford First discover "transmutation" from element to other element which determine by their atomic and mass numbers.
What does the atomic mass of an element measure?
Atomic mass of an element measures the mass of that element on a molecular scale, taking into account neutrons and protons, which weigh approximately 1. Electrons are negated. Atomic mass is also the mass, in grams, of 1 mole of that element.
Why mass of electrons is excluded from atomic mass?
The mass of electrons is not excluded from atomic mass. The mass number of an isotope of an element excludes electrons because it is the sum of protons and neutrons.From Wikipedia, "The atomic mass (ma) is the mass of a specific isotope, most often expressed in unified atomic mass units. The atomic mass is the total mass of protons, neutrons and electrons in a single atom."
What is the mass of an ion with 107 electrons?
The mass of an ion with 107 electrons would depend on the specific element of the ion. You would need to know the atomic number of the element to calculate the mass accurately using the atomic mass of the element.
Does the mass number equal the same number of electrons?
The atomic mass number does not equal the number of electrons in the element. The atomic number, on the other hand, does usually equal the number of electrons in the element, With the exception of ions.
What element in the periodic table has atomic mass of 230 with 86 electrons?
Rn has 86 electrons, Th is the closest to having an atomic mass of 230
When does the atomic mass of an element represent?
The average total mass of its neutrons,protons and electrons
