The Atomic Mass tells how much amu one atom of an element weighs. It, minus the atomic number, rounded to the nearest one, gives you the number of neutrons in an atom. The atomic number is the number of electrons and protons. Protons have a positive charge, electrons have a negative charge, and neutrons are neutral.
What else can I help you with?
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.
Can the atomic mass of individual atoms of an element vary?
The mass of an atom will always remain constant, but various isotopes of the same element may have differing atomic masses. For example, a given hydrogen atom could have a mass of 1 amu, 2 amu, or 3 amu, but it could not switch between them.
When 2 atoms appear to have same atomic mass?
When they are of the same element.
What number on the periodic table represents the mass in grams of one Mole of atoms in an element?
The number on the periodic table representing the mass in grams of one mole of atoms in an element is called the molar mass, which is expressed in grams per mole. It is numerically equal to the atomic mass in atomic mass units (amu) of the element.
How many atoms are in an element whose mass is equal to the atomic mass?
1
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
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 tells you how many atoms of an element there are?
the atomic mass, which is the mass of its protons and neutrons and electrons together
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 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
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.
How many atoms are there in an element?
The number of atoms in an element depends on the element's atomic mass and the amount of the element present. One mole of an element contains approximately 6.022 x 10^23 atoms, known as Avogadro's number.
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.
