I'm Blurred out in Chemical equations,
why is hydrogen H2 and oxygen is O2?! -
because they both have 1 unpaired electron that would love to form a covalent bond with another unpaired electron.
-
but i thought hydrogen only have 1 electron?Originally posted by beavan:because they both have 1 unpaired electron that would love to form a covalent bond with another unpaired electron. -
that is why Hydrogen shares another electron with another hydrogen atom to form a stable duplet config.

Hydrogen can gain or lose 1 electron to be stable.
Oxygen have to gain 2 electrons to be stable. -
oh that's why it's H2, O2?Originally posted by ndmmxiaomayi:Hydrogen can gain or lose 1 electron to be stable.
Oxygen have to gain 2 electrons to be stable. -
You sure are extremely lost for a student of chemistry!

wah xmm u knw so many thing haha I cannot even remember my chem back in sec sch...Originally posted by ndmmxiaomayi:Hydrogen can gain or lose 1 electron to be stable.

according to the periodic table H has a atomic number of 1,O has an atomic number of 8.Originally posted by kenn3th:oh that's why it's H2, O2?
for H,it has 1 electron at its outermost shell since its atomic number is 1.
It needs 2 electrons to be stable.so how?share with another H atom lor....the sharing is called covalent bonding.
for O,roughly the same concept.
O's atomic number is 8....its electron configuration is 2,6...so outermost shell has 6 electrons.It needs 8 to be stable.so share 2 electrons with another O atom.
therefore U have H2 and O2. -
wah u ple eh sai..
i returned everything to my chem teacher.

I dun remember any stable atom without electrons.Originally posted by ndmmxiaomayi:Hydrogen can gain or lose 1 electron to be stable.
I might be wrong though.

Don't know, my chem teacher says can. Since no electrons or protons to balance, it's left with neutrons = 0 charge. Hydrogen happy can liao.Originally posted by Xcert:I dun remember any stable atom without electrons.

Hydrogen has no neutrons - unless if you're talking about deuterium or tritium.Originally posted by ndmmxiaomayi:Don't know, my chem teacher says can. Since no electrons or protons to balance, it's left with neutrons = 0 charge. Hydrogen happy can liao.
If it loses its electron, it becomes one single proton with a net +1 charge.
So it has to share its electron with another hydrogen atom to form a stable duplet configuration. -

actuali gaining n losing is mainly for metal with non-metal compounds, tt is when they form ionic products...Originally posted by ndmmxiaomayi:Hydrogen can gain or lose 1 electron to be stable.
Oxygen have to gain 2 electrons to be stable.
when its non-metal n non-metal is form covalent compound, tt is when they share electrons...
eg. hydrogen has 1 electron, share with another hydrogen, so both of them haf 2 electrons, thus stable(1st principle quantum shell can hold 2 electrons).
oxygen has 6 electrons on its outermost shell, thus it needs 2 more to haf a stable octet structure, therefore it shares 2 electron with another oxygen atom, O::O, therefore 4 in the middle + 4 remaining ones arnd it to form 8 electrons...
or if u wan easy way out, most gaseous elements exist as diatomic molecules... -
they are gas then have 2
