(2Q) Chemical Bonding and The Shapes of Molecules

This type of interaction is observed between atoms with large differences in their tendencies to lose or gain electrons and is achieved via electron transfer

Once the electrons of an ionic bond have been transferred to the non-metal, both the metal and the nonmetal become ___.

In ionic bond: Metal is ____ charged and Non-Metal is _____ charged.

tend to have higher melting and boiling points.

They are hard and brittle and conduct electricity when dissolved in water.

are formed when atoms reach stability by sharing electrons (rather than fully gaining or losing them)

The more electrons that are shared between two atoms, the _____ and _____ their bond will be.

are brittle solid, have relatively low melting and boiling points, and are poor conductor of heat and electricity

high vapor pressure, which makes them volatile and good as fuels.

Lewis structure created by

Most metals have how many valence electrons? This can be easily removed because of their relatively low ionization energy

Nonmetals, having high electron affinity, can

is the difference between the valence electrons in an isolated atom and the number of electrons assigned to that atom in a Lewis structure

It is imperative to remember that atoms are more stable when they have

Negative formal charges should be assigned to more

the angles and distances between each atom, bonding pair, and lone pair of electrons are determined by the

the size and shape of a molecule of a substance, together with the strength and polarity of its bonds, affect the

The approach in predicting molecular geometry

VSEPR Theory is anchored from the assumption that all electron pairs in the valence shell around a central atom _________

In VSEPR Theory, electron pairs stay far apart from each other to?

is determined by the number of bond pairs and lone pairs around the central atom.

In VSEPR Theory, you should treat multiple bonds as?
