Remember 1s2 2s2 2p6... If you draw an electron diagram(s 1 box, p3 boxes...) for an atom, you will find how many unpair electrons it has(unpaired electron:an electron that occupies an orbital of an atom singly, in the diagram, only 1 electron in a given box) Lone pair is the when you draw a bonding diagram, how many pairs the central atom has are how many pairs of lone pairs.

∙ 15y agoVery few atoms use all their valence electrons to form covalent bonds. When an atom has electrons that are not used for bonding, they remain on the atom itself as a lone pair---a pair of electrons that is not involved in bonding. For instance, in water you have two hydrogens and an oxygen bonded together. The oxygen uses two of its valence electrons to form bonds with the hydrogens (one for each bond). The remaining 4 valence electrons in oxygen are found in two lone pairs.

∙ 9y agoA lone pair of electrons is a group of two valence electrons that are not bonded to anything. They do not share bonds with other atoms, despite being located near the central atom.

What is A pair of electrons not involved in bonding called?
Such pairs of electrons are called as lone pairs.
What type of bonds can fluorine create and why?
diatomic as it has a lone outer electron that can pair with another lone outer electron on another atom
What effect does lone pair electrons have on molecular shape?
The lone pair pushes bonding electron pairs away.
What is the shape of the molecul nitrogen trifluoride?
NF3 has trigonal pyramidal shape. Around nitrogen, there are 1 lone pair electron and 3 bond pair electrons. The lone pair-bond pair electron repulsion is greater than bond pair-bond pair electron repulsion. The angle between N-F bond pairs are 107 degrees
What is the hybridization of the central sulfur atom in SF4?
It should be sp3d. first draw the Lewis structure. then you can see the central S atom has 4 bonding pair and 1 lone pair. then draw molecular orbital. Distribute electron according the bonding and lone pair. the paired electron represent lone pair in Lewis structure. and the other unpaired electron distribute in the molecular orbital represent the number of bonding pair in Lewis structure
Diffirences of bonded and lone pair electron?
The difference between bonded and lone pair is that a bond pair is composed of two electron that are in a bond whereas lone pair is composed of two electron that is not a bond.
What does a lone electron pair have on molecular shape?
The lone pair pushes bonding electron pairs away.
What is the difference between lone pair and bonding pair electron?
they are the same. Lone pair is unshared pair of electrons and bond pair is shared pair of electron.
What effect does a lone electron pair have a molecular shape?
The lone pair pushes bonding electron pairs away.
What effect does a lone electron pair on molecular shape?
The lone pair pushes bonding electron pairs away.
What effect does a lone electron pair have on molecular shape?
The lone pair pushes bonding electron pairs away.
What effect does a lone electron have on a molecular shape?
The lone pair pushes bonding electron pairs away.
Does iron have a lone pair of electron?
iron has unpaired electrons. the term 'lone pair' is not used for metals
What is A pair of electrons not involved in bonding called?
Such pairs of electrons are called as lone pairs.
What type of bonds can fluorine create and why?
diatomic as it has a lone outer electron that can pair with another lone outer electron on another atom
What effect does lone pair electrons have on molecular shape?
The lone pair pushes bonding electron pairs away.
Which molecules has one lone pair of electrons CH4 or h2o or hci or nh3?
nitrogen aton in NH3 has one lone pair of electron
