Electronic Structure of Matter

It is a representation of the valence electrons of an atom that uses dots around the symbol of the element. ...

• Lewis Diagram

• Langmuir Diagram

• Kossel Diagram

These are electrons found in the subshells of the highest principal quantum number.

• Valence Electrons

• Neutrons

• Protons

They were long believed to be totally unreactive but compounds of xenon, krypton, and radon are now known.

• Noble Gases

• Alkali Metals

• Halogens

• Transition Metals

They proposed that atoms tend to acquire the electron configuration of a rare gas.

• Gilbert Lewis

• Irving Langmuir

• Walther Kossel

• Dimitrii Mendeleev

It refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.

• octet rule

• quartet rule

• quintet rule

• trio rule

These are abbreviations used in chemistry for chemical elements, functional groups and chemical compounds.

• Chemical Symbols

• Scientific Symbols

• Element Symbols

It is placed at any time on the four sides of the symbol.

• dot

• line

• period

It is the lowest energy state where electrons normally exist.

• ground state

• upper state

• corner state

The electron is said to be in excited state when it goes into a lower energy state.

• TRUE

• FALSE

He proposed the fixed energy level which was supported by the emission spectrum of Hydrogen.
