Ionization energy trend Ionization energy is defined as the amount of energy needed to eject a valence electron from an atom in the gas phase. It is measured in kJ/mol. A valence electron is simply an electron located in the Read More …
Today, we are going to learn about how the periodic table is organized and the important information that it provides.  Scientists discovered that if they arranged the elements according to their atomic number, properties of the elements would occur Read More …
The above is an example of electronegativity bond scale.It shows the different types of chemical bonds formed between atoms based on the electronegativity difference. Bond scale varies slightly from text book to text book. For example, some text book show Read More …
What is the Octet Rule of Electron Configuration? Electron configuration is the arrangement of electrons in each energy level or orbit of an atom. If the outer shell of an atom is not filled to its maximum level, the atom Read More …
Definition The valence electrons are the electrons in the outermost shell or last energy level of an atom. Valence electrons are electrons in the highest principal energy level. They are electrons that sit on the outermost orbit of an element. Read More …
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.
