What is the difference between atomic mass?
Atomic mass refers to the mass of an atom of a chemical element, which is the sum of the number of protons and neutrons in the nucleus. On the other hand, molecular mass refers to the sum of the atomic masses of all the atoms in a molecule, including the contributions from electrons. In general, atomic mass is specific to individual atoms, while molecular mass relates to groups of atoms bonded together.
Why does not atomic mass of element represent the actual mass of the atoms?
Because the gram atomic mass of an element is the mass in grams of Avogadro's Number of atoms. To find the actual mass of a single atom, the gram atomic mass must therefore be divided by 6.022 X 1023.
Are all sample of elements are composed of atoms with same atomic mass?
No, different samples of an element can have varying atomic masses due to the presence of isotopes. Isotopes are atoms of the same element with different numbers of neutrons, leading to different atomic masses.
Do atoms of each element have a unique mass?
Generally, yes. However, isotopes are each of two or more variant of an element and will contain the same number of protons, but different numbers of neutrons. Therefore they will have different masses.
When 2 atoms appear to have same atomic mass?
When they are of the same element.
How are atomic number and atomic mass alike?
Atomic number and atomic mass are not alike. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Atomic mass is the combined masses of the protons, neutrons, and electrons of the atoms of an element. Individual isotopes of an element have specific mass numbers, which are the sum of the protons and neutrons in the nuclei of the atoms of the isotope.
What is the relationship between the atomic mass of an element and a mole of that elements atoms?
The mole is the atomic weight expressed in grams.
What does an element's atomic mass tell about the atoms that make up that element?
Atomic Mass is the no. of protons+no. of nuetron
What does an element's atomic mass tell us about the atoms that make up that element?
atomic mass is the no. of protons+no. of nuetron
How can you fine the mass of mole of atoms of atoms of an element in grams?
Simple: the atomic weight expressed in grams. Example for dysprosium - 162,500 grams.
What tells you how heavy an element's atoms are compared with atoms of other elements?
The atomic mass of an element tells you how heavy its atoms are compared with atoms of other elements. Atomic mass is the average mass of an atom of an element, taking into account all its isotopes and their abundance.
What does the atomic mass of an element tell?
The gram atomic weight or gram Atomic Mass of a chemical element is the mass in grams of Avogadro's number of atoms of the element with the isotopic proportions found in nature.
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.
The atomic mass of an atom is the?
The atomic mass of an atom is the mass of 6.011 X 10^23 atoms of that element.
What are atoms of an element have the same atomic number but a different atomic mass?
isotope
