Which is the correct lewis structure for ethylene, c2h4?
1 answer:
Remember this, when trying to find a valid lewis structure, every single atom must have a total of 8 shared electrons (full octet). Since I only have 4 hydrogens to work with, two on each carbon, I assumed a double bond in the middle. This way, every atom has a full octet, except for hydrogen which is most stable with just two electrons. If there were just a single bond in between the carbons, each carbon would only have a total of 6 shared electrons which violates the octet rule. So a double bond is a must. This is ethylene by the way.

Answer: incorporates both ionic bonding and covalent bonding.
Explanation:
A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.
An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal.
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here potassium is having an oxidation state of +1 called as cation and nitrate
is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
.
is formed by sharing of electrons between two non metals nitrogen and oxygen.
Thus incorporates both ionic bonding and covalent bonding.
