How many equivalent Lewis structures are there for CO32-?
There are three equivalent Lewis structures for CO32.
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.
Why are electron dot structures sometimes called Lewis dots or Lewis structures?
Electron dot structures are sometimes called Lewis dots or Lewis structures because they were introduced by American chemist Gilbert N. Lewis in the early 20th century. Lewis used dots, or small circles, to represent valence electrons around atoms in a chemical structure, which is why these diagrams are often referred to as Lewis dots or Lewis structures.
How can Lewis theory be used to determine the formula or ionic compounds?
"To use Lewis theory to determine the formula of an ionic compound, determine the number of valence electrons lost by the metal to form an octet, and the number of electrons gained by the nonmetal to form an octet." Refer the link below for further reading.
How many equivalent Lewis structures are nescessary to describe SF4?
Two equivalent Lewis structures are necessary to describe SF4. These structures differ in the arrangement of the lone pair on sulfur, resulting in resonance structures.

What is the first thing you should do if you want to determine if a molecule is polar or not?
Check the molecular geometry to determine if the molecule is asymmetrical. If the molecule has a symmetrical shape, it is likely nonpolar. If it is asymmetrical, check for polar bonds and the overall molecular polarity.
What is Lewis theory?
Lewis theory, developed by Gilbert N. Lewis, is a conceptual framework in chemistry that describes how atoms bond together to form molecules. It emphasizes the role of electron pairs in chemical bonding, specifically through the sharing of electrons (covalent bonding) and the transfer of electrons (ionic bonding). The theory uses Lewis structures to visually represent molecules, showing valence electrons as dots and bonds as lines, which helps predict molecular geometry and reactivity. Overall, Lewis theory provides a foundational understanding of molecular structure and bonding interactions.

Why do neon and helium have different number of dot in their Lewis structures if they are in the same group?
Neon and helium have different number of valence electrons, which determine the number of dots in their Lewis structures. Helium has 2 valence electrons and will have 2 dots in its Lewis structure, while neon has 8 valence electrons and will have 8 dots in its Lewis structure, following the octet rule.

Two equivalent Lewis structures are necessary to describe SF4. These structures differ in the arrangement of the lone pair on sulfur, resulting in resonance structures.
How many equivalent Lewis structures are necessary to describe the bonding in PO(OH)3?
In chemistry, resonance is a way of describing bonding in certain molecules or ions by the combination of several contributing structures (or forms, also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory
How many equivalent Lewis structures are necessary to describe the bonding in BrO4?
Two equivalent Lewis structures are necessary to describe the bonding in BrO4 due to the presence of multiple resonance structures.
Who is the inventor of Lewis Structures?
The Lewis structures were introduced by the American chemist Gilbert N. Lewis in 1916. Lewis proposed the concept to represent the bonding between atoms in a molecule using simple symbols and dots to denote valence electrons.
Who found octet theory?
Lewis
