Electron dot structure for
Concept introduction:
Electron dot structure is a representation of covalent bonding that indicates where the valence shell electrons are in the molecule. Shared electron pairs are shown as lines and lone pairs are shown as dots.
Example:
Bond order describes, if a bond is single bond order is one, if it is double bond order is 2.
Bond length is the distance between the centers of two atoms joined by a covalent bond.
Higher bond order corresponds to shorter bond length.
The bond length and bond order of some molecules are listed below,

Give examples of the ways a Cl atom can do so.arrow_forwardIf a silicon is replaced by an aluminum in a silicon oxide structure, how is charge neutrality maintained?arrow_forwardIn what ways are the electronic structures of the group 14 (4A) elements similar? In what ways are they different?arrow_forward
- Why does CO2 have a linear shape with no dipole moment?arrow_forwardWhat is the valence electron configuration for Group 4A elements? Group 4A contains two of the most important elements on earth. What are they, and why are they so important? How does metallic character change as one goes down Group 4A? Why is the chemistry of carbon dominated by bonds, whereas that of silicon is dominated by bonds? What are the two allotropes of carbon?arrow_forwardFluorine lies between oxygen and neon in Period 2. Whereas atomic sizes and ionization energies of these three elements change smoothly, their electronegativities display a dramatic change. What is this change, and how do their electron configurations explain it?arrow_forward
