What is the number called that tells the combining ability of an atom?
valence
Tetravalence of carbons most directly results from?
its four electrons in the valence shell that can form four covalent bonds
What do you notice in the number of valence electrons of metal?
The ability of an atom to loss this number of electrons.
What happens during the hydrogenation of ethylene?
2-ethylhexane. This is because the hydrogenation causes the double bonds to be replaced with an H-H to fill the carbons valence vacancies.
Why is diamond harder than quartz?
Diamond has stronger bonding because of the fact that it has 2p valence orbit whereas Silicon has 3p valence orbit. Moreover we know that as we go farther away from Nucleus the shielding of electrons takes place.Due to this shielding, the bonding becomes weaker. In case of Silicon carbide and Silicon dioxide 3p orbits are participating in bonding. Hence the shielding leads to weakening of bond.Shielding is not there in case of Diamond as mentioned. Hence this is the reason why Diamond is harder.
Which elements contain the same number of valence electrons as carbons?
silicon (Si). -apex
Carbons valence electrons?
A carbon needs 8 electrons to have a solid shell so it usually form 4 other bonds to combine with the 4 electrons it already has

valence
The name of what french city on the rhone river describes the ability of an atom to combine with another atom?
Valence is the ability of an atom or a group of atoms to combine with other atoms or groups of atoms. Valence, France is located on the left bank of the Rhone, along the railway line that runs from Paris to Marseilles. Valence citizens are called Valentinois.

2-ethylhexane. This is because the hydrogenation causes the double bonds to be replaced with an H-H to fill the carbons valence vacancies.
What elements make up octane?
The elements in octane are simply carbon and hydrogen. There are eight carbons which are covalently bonded together in a line, and since the carbon has to fill its valence shell it has hydrogens attached to the free electrons. Carbon needs to bond to four elements to have a full valence shell.
What is chemically nonsensical about this structure?
Carbon (C) has four valence electrons (electrons in the outer shell) and it needs 4 more to fulfill the octet (8) rule. Therefore carbons will make four bonds. The structure H-C=C-H is nonsensical because the carbons only have 3 bonds each.
What determines the reactive of an element?
The number of valence electrons determines reactivity. Valence electrons are the number of electrons in outermost shell.
How many valence electrons are in the molecule acetic acid CH3CO2H?
The molecular formula for acetone is CH3COCH3. There are 3 carbons with 4 valence electrons each, 1 oxygen with 6 valence electrons and 6 hydrogens with 1 valence each. This means that there are 24 valence electrons in acetone.
How many protons in carbons?
6 protons 6 neutrons 6 electrons 4 valence electrons
