:Structure of SiF4 is a regular tetrahedron, any regular geometry has net zero dipole moment as all individual dipole in a molecule cancel the effect of each other. About paramagnetic behaviour of oxygen gas, according to the Molecular Orbital theory oxygen has two unpaired electron in its Pi anti bonding molecular orbital, which is the cause of their paramagnetism.
SiF4 is a covalent bond because it is formed by sharing electrons between silicon and fluorine atoms.
The bond type present in the molecule CH2Cl2 is a covalent bond.
In silicon dioxide, a type of bond called a covalent bond is formed.
ionic bond
polar covalent - use the electronegativity difference
SiF4 is a covalent bond because it is formed by sharing electrons between silicon and fluorine atoms.
SiF4 is a covalent molecule. The rule that a bond is ionic if the difference in electronegativities is >1.7 is only a rule-of-thumb. It has a low melting point etc. and all the characteristics of a covalent molecular substance. The covalent bonds however are very polarised and SiF4 is rapidly hydrolysed by water.
Electrons are shared in a type of bond known as covalent. This type of bond is also considered a chemical bond.
The bond type present in the molecule CH2Cl2 is a covalent bond.

A junk bond is one which is of very high risk. This type of bond will mean that a person may never get the money back which they invest into the bond itself.
