Atomic Mass: Atomic mass refers to the weight or mass of an atom of a specific element. It includes the mass of the protons, neutrons, and electrons in the atom. We measure it inAtomic Mass Unit(amu). Element T
Using iron as an example, iron will commonly lose either two or three electrons, but it is stable losing up to six electrons, or gaining up to two electrons. Vocabulary Review: Group: The columns of the periodic table Period: The rows of the periodic table Atomic number: The number of ...

The Periodic Table of the Elements is a very useful tool in science, especially chemistry, as its organization is periodic with respect to many physical characteristics of the elements. One of these is electronegativity which is a measure of an element's attraction for electrons shared in a bond...
If you look at the 'periodic table', elements of the metallic property exist separately, whereas very large energy is needed in order to remove electrons from a substance consisting of non-metallic elements that doesn't use in the power plant (See Fig.2.1). Then, of course, a big piece...
To understand how electrons bond together let's take a look at water(H2O). By looking at the periodic table we see that Hydrogen has an atomic number of one. This means that it has one electron in its 1S orbital. Now because this electron is unpaired, it can be used for bonding. Oxy...
Electronegativity is a measure of how much a particular element wants electrons. In the Resources section you will find a periodic table which reports the electronegativity of each element. The higher this number, the more an atom of that element will "hog" the electrons in a bond. ...
The octet rule states that atoms will share or borrow electrons in order to reach the number of valence electrons of the nearest noble gas. 1. Identify the Cation The cation is the element looking to lose electrons. These elements are in Groups I-IV on the periodic table. Group I can lo...
Since the atom is neutral, the number of electrons is equal to the proton number. There are 46 electrons in aPdatom. Example 3 How many electrons does aP3−ion have? Step 1:Identify the proton number, also called atomic number, of the element on the periodic tab...
Chemists use equivalent units, or equivalents, to express the reactive capacity of a chemical species, such as electrons or ions like H+. The equivalent defines how many electrons or ions may be transferred in a chemical reaction. For example, in the aci
