tetravalent

But since carbon is tetravalent, it has the ability to form one more bond.

Sharing the same group with carbon, lead is tetravalent.

The disadvantage is that tetravalent uranium compounds precipitate as well.

Tetravalent americium has also been observed in the aqueous phase.

The carbon atom is called tetravalent because it forms 4 covalent bonds.

It is believed to exhibit resonance between its tetravalent and divalent carbon forms.

Thus the Si atom is tetravalent (has four bonds).

Uranium in its tetravalent (uranous) state is very important in different technological processes.

As tetravalent transition metals, all three elements form various inorganic compounds, generally in the oxidation state of +4.

First used in 1945, the tetravalent vaccine was not widely distributed, since its deployment coincided with the discovery of penicillin.

Silicon, a tetravalent metalloid, is a chemical element with the symbol Si and atomic number 14.

There is some confusion about whether the oxidised manganese is tetravalent or trivalent.

In most organosilicon compounds, Si is tetravalent and tetrahedral.

The basis of this model followed the earlier 1855 suggestion by his colleague William Odling that carbon is tetravalent.

Therefore, the angles between bonds of a tetravalent carbon atom have a preferred value θ 109.5 .

Through that pair, nitrogen can form an additional bond to hydrogen making it tetravalent and with a positive charge in ammonium salts.

William Odling proposes that carbon is tetravalent.

This trivalent state is the most stable, especially in aqueous solutions, but tetravalent berkelium compounds are also known.

Owing to lack of electrons on 6d and 5f orbitals, the tetravalent thorium compounds are colorless.

Thus tetravalent protactinium in solutions is obtained by the action of strong reducing agents in a hydrogen atmosphere.

Curium can be tetravalent in solids (fluoride, dioxide).

These monomers then bind to a backbone, such as streptavidin or avidin, creating a tetravalent structure.

Another known form of solid tetravalent americium chloride is KAmF.

Tetravalent uranium, however, quickly precipitates in mineral form, locking it up in the sediment or bedrock.

Silicon (symbol Si) is a tetravalent metalloid.
