The periodic table lists the atomic mass and molar mass of each element. The values are the same, but their units are different. Atomic mass has the units atomic-mass-units, or AMU. Molar mass is the mass of one mole of the element, which is the mass of Avogadro's number of atoms ...
1.how are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on the periodic table?2.how does the number of electrons relate to the arrangement what is the different in the number of electrons in a 3rd period element and the 2nd period ...
Gram Molecular Mass: The gram molecular mass is the same idea as the molar mass of a substance. The periodic table lists all of the elements' molar masses. It is the average of all of the isotopes of that element. Answer and Explanation:1 ...
Molar Mass of HCl: 36.46 g/mol ElementSymbolAtomsMass % Hydrogen H 1 2.8% Chlorine Cl 1 97.2% TL;DR (Too Long; Didn't Read) Atomic number is the number of protons in the nucleus of an element. It defines the position of the element in the periodic table. Atomic weight, which is...
The amount of protons and neutrons together is themass numberbecause electrons are so light. Atomic number denotes the element. Mass number can change depending on the amount of neutrons the atom contains. Atoms that are the same element but have different masses are isotopes. ...
Electrons orbit around the atom's nucleus just like planets orbit the sun. True or false? What is the average atomic mass of Element X if 51.83% of Element X occurring in nature has a mass of 106.905 amu and 48.17% of the atoms have a mass...
