What else can I help you with?
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.
Tells you the number of atoms in each element?
atomic mass is the answer
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
What is the atoms mass number?
The Atomic Mass number tells how many protons and neutrons are in a nucleus.
What does an elements atomic mass tell about the atoms that make up that element?
It tells you the mass of how many protons and how many neutrons plus the tiny mass of the electrons. The electrons are about .0016 amu so they still have mass
What the atomic mass tell the total number of?
The Atomic Mass of an element tells you what the mass of one mole (6.022 x 1023 atoms) of the element is. It sort of tells you the number of protons & neutrons in the atom, but that is not necessarily precise.
What does percent composition tell you about a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
How many Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
What is the number of magnesium atoms that equal to a mass of 24.31 g?
To calculate the number of magnesium atoms, you first need to determine the molar mass of magnesium, which is 24.305 g/mol. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the mass to number of atoms. Finally, divide the given mass by the molar mass of magnesium and multiply by Avogadro's number to get the number of atoms, which is approximately 6.022 x 10^23 atoms.
Is fusion nuclear decay or nuclear synthesis?
Fusion is nuclear synthesis, combining atoms of lesser mass into atoms of greater mass. Decay is reducing the mass of larger (unstable) atoms to form atoms of lesser mass.
What is the mass of x atoms of sulfur?
208
What do you use the periodic table for?
we use the periodic table because it helps us with the atoms and electrons it tells us the mass number atomic number and the symbol
