Which scientist described a base as a compound that donates an electron pair?
Gilbert Newton Lewis described a base as a compound that donates an electron pair. This concept is known as the Lewis acid-base theory, which was proposed in 1923. Lewis also introduced the idea of electron pairs being shared in covalent bonds.
What is an atom that donates an electron called?
A substance that can donate a lone pair of electrons is called a Lewis base. The definition of a Lewis base is a compound or ionic species that can donate an electron pair to an acceptor compound.
When does a covalent compound have resonance?
A covalent compound exhibits resonance when it can be depicted by different Lewis structures with the same arrangement of atoms but differing in the distribution of electrons. This indicates that the actual electron distribution is a hybrid of the different resonance structures.
How can one identify whether a substance is a Lewis acid or base?
A substance can be identified as a Lewis acid if it accepts an electron pair, and as a Lewis base if it donates an electron pair. Lewis acids are electron pair acceptors, while Lewis bases are electron pair donors.
How many equivalent Lewis structures are there for CO32-?
There are three equivalent Lewis structures for CO32.
What are the symbols that use electron dot notation to represent molecules called?
The symbols that use electron dot notation to represent molecules are called Lewis structures. These structures use dots to represent valence electrons around atoms in a molecule.
How electron dot diagrams are also called?
They can also be called Lewis Dot Structures or Diagrams, named after a scientist names Gilbert Norton Lewis
What is Lewis formula?
Lewis structures are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. They are also called Lewis dot diagrams, electron dot diagrams, and electron dot structures. See the link below for Lewis structure.

Lewis dot diagrams are used to represent what?
Lewis dot diagrams represent electron distribution within a molecular compound. Lewis dot structures are a simple way to show how electron pairs are involved in bonding and which atoms are being bonded in a compound.

A substance that can donate a lone pair of electrons is called a Lewis base. The definition of a Lewis base is a compound or ionic species that can donate an electron pair to an acceptor compound.
When does a covalent compound have resonance?
A covalent compound exhibits resonance when it can be depicted by different Lewis structures with the same arrangement of atoms but differing in the distribution of electrons. This indicates that the actual electron distribution is a hybrid of the different resonance structures.
What are the diagrams that show the number and distribution of valance electrons within molecules?
For bonding between atoms we usually show the dot-cross diagram representing the outer most electrons of bonded atoms.
Why is VSEPR theory better than Lewis?
VSEPR (Valence Shell Electron Pair Repulsion) theory provides a more intuitive understanding of molecular geometry by focusing on the spatial arrangement of electron pairs around a central atom, rather than just the electron sharing depicted in Lewis structures. While Lewis structures can represent bonding and lone pairs, VSEPR effectively accounts for the repulsive interactions between these electron pairs, leading to accurate predictions of molecular shapes. Additionally, VSEPR simplifies the complexity of molecular geometry by categorizing shapes based on electron pair arrangements, making it easier to visualize and understand molecular structures.

Can polyatomic ion form Lewis structures?
Yes, polyatomic ions can form Lewis structures. A Lewis structure shows how valence electrons are arranged in a molecule or ion by representing bonds and lone pairs of electrons. The same rules for determining octet/duet stability apply to polyatomic ions as to neutral molecules.
How many equivalent Lewis structures are there for CO32-?
There are three equivalent Lewis structures for CO32.
