Wee 100th comment in this thread well 101.... if you count the 1st one...

 

[Miss Sunshine]

haha ok never mind! too fast for me!

 

[ZacA888]

So what about waves?

 

[Deer]

Reactivity:

Elements in columns (verticle) have the same reactivity (valency: amount of electrons away from having a full outer shell) due to having the same electron configuration, therefore same chemical properties. called groups.
Rows (periods) have the same number of outer shells holding electrons.

 

[Miss Sunshine]

what are the advantages of a series circuit?

 

[Deer]

Group 1 and 7 is one electron away from being stable, therefore is VERY REACTIVE. (really wants that electron)
Group 2 and 6 are 2 away, therefore is reactive, but not as muchas group 1 and 7.
Group 8 are called noble gases because they have full outer shell, are inert (do not react)

Require less energy because the voltage is the same? Not sure.

 

[Deer]

Oh dear, i dont know!
I know the disadvantages are that if one lightbulb breaks, all the others do too because the circuit is broken, unlike parallel, where one can break and the remaining still work.

edit:

also, in series the lightbulbs get dimmer because the current decreases past each bulb, but in parallel they are all equal because the current is shared.

So which one splits in a parallel circuit? Voltage or current? T.T

 

[xV1P3R]

I guess it'd require less wiring and probably less electricity as can be seen with Christmas lights- a lot of them but not pretty dim.
Q: Law of Conservation of Matter

You seem lost... current is what travels in the circuit
Voltage is the amount put into the circuit.

State it?
Matter can neither be created or destroyed. It only converts from one form to another.

current splits in parallel, voltage stays the same

Voltage is the amount put into the circuit.

So current splits...?




^ okay thank you

Yeah basically ^_^

 

[Miss Sunshine]

What are some ways fossils can be formed?

 

[Brontecat]

the most reactive element is Francium like xV1P3R said but it goes down group one and furthest left to find it.

As a general rule groups 1, 2 and 3 want to gain electrons to fill their shells, whereas groups 4, 5, 6 want to lose electrons to make themselves stable.
All of group 8's valence shells are full.

Waves
LIGHT WAVES
Wavelength - distance from one wave to another in the same place
Amplitude - height of wave from the medum
Trough - the bottom tip of a wave below the medium
Crest - the top of a wave above the medium

Frequency - is found by how how many waves appear (note: full wave includes both crest & trough)

SOUND WAVES
........ . . . . . . . . . .........
........ . . . . . . . . . . .........
........ . . . . . . . . . . .........
( Rarefraction ) Compression

To remember think RAREfraction RAREly any dots
COMPRESSION dots are COMPRESSED

Another thing to be aware of with waves is the doppler effect which just means high pitch to low pitch, like when a car going faster than you drives past it sound higher then it sounds lower.

ELECTRICITY
Another thing to remember with the relationship between voltage, current and resistance is that is is exactly like the distance over time x speed thing, it forms a pyramid. The voltage replaces distance; resistance, time; and current, speed.

btw GOOD LUCK WITH SCIENCE TOMORROW

i probs wont be doing to well - stupid mc skills i'm so bad at them but know all the stuff

 

[dc1337]

Frequency is number of waves passing a point per second. Measured in hertz

 

[Deer]

Me too
Science isn't too bad, but english... *fumes*

What are some ways fossils can be formed?

Underwater - dies, buried under mud/sand
Land - dies, squished under layers of mud/sand/rock?


State Ohm's Law and what it is used for.
