What is correctly represented by a long dash i n a Lewis structure molecule?
A long dash in a Lewis structure molecule typically represents a shared pair of electrons (a covalent bond) between two atoms. It signifies the sharing of electrons between the bonded atoms to achieve a stable electron configuration.
What type of covalent bond diagram only shows the outer shell of electrons?
A Lewis structure or electron dot diagram only shows the outer shell (valence) electrons of atoms participating in covalent bonding. This type of diagram helps visualize how electrons are shared between atoms to form covalent bonds.
Can more than one pair of electrons be shared?
Yes, more than one pair of electrons can be shared between two atoms in a covalent bond. For example, in a double bond, two pairs of electrons are shared, while in a triple bond, three pairs of electrons are shared. Each shared pair of electrons represents a strong bond between the atoms involved.
What is the electron dot diagram for chlorine gas?
The electron dot diagram for chlorine gas (Cl2) shows two chlorine atoms sharing a pair of electrons to form a covalent bond. Each chlorine atom has 7 valence electrons, so when they come together, they each contribute one electron to the shared pair.
Dot and Cross diagram for c2h2?
In a dot and cross diagram for C2H2 (ethyne), you would draw two carbon atoms each with a triple bond between them. Each carbon atom will have two hydrogen atoms attached. The dot represents a shared pair of electrons and the cross represents a lone pair of electrons.
