Why would the atomic number be better to identify an element than the atomic mass? How are atomic numbers and mass numbers written? What is counted in an atom to determine mass number? What is the difference between a dalton (u) and an atomic mass unit (amu)?
However, there are some modifications to the Daltons theory now with more advanced finding about the atom. Molecule Molecules are made up by chemically bonding two or more atoms of the same element (e.g. O2, N2) or different elements (H2O, NH3). Molecules don’t have a charge, and the...
• The properties of an element often change completely when they are part of a compound. • There are strong covalent bonds between atoms of the compound, but in elements, there can be metal bonds, or weak non-covalent forces.
An atom is the smallest unit of an element retaining its properties, while a molecule consists of two or more atoms bonded together. Difference Between Atom and Molecule Table of Contents ADVERTISEMENTKey Differences An atom represents the most basic unit of an element that retains all of its ch...
Difference Between Magnesium Atom and Magnesium Ion Table of Contents ADVERTISEMENTKey Differences A Magnesium Atom is the basic unit of the element Magnesium, consisting of 12 protons, 12 neutrons, and 12 electrons, making it electrically neutral. A Magnesium Ion, particularly a Magnesium cation (Mg...
Both atomic mass and atomic weight relyon the atomic mass unit(amu), which is 1/12th the mass of an atom of carbon-12 in its ground state. Can Atomic Mass and Atomic Weight Ever Be the Same? If you find an element that exists as only one isotope, then the atomic mass and the...

Electronegativity is the tendency of an atom to attract electrons toward itself. Table 2(a) shows the electronegativity values for elements in the first two rows of the periodic table. The greater the difference between electronegativity values, the more ionic character the bond will possess. ...
The Anomers and Epimers both differ in one carbon atom. The Anomers and Epimers are both found in sugar molecules. The Anomers and Epimers are both formed due to the differences in the position of only one hydroxyl group. Difference Between Anomers and Epimers ...
