有点
肯定来不及~可能明年才拿

够力，酱都可以
酱你不是明年才知道你的成绩咯

Proton number is the number of proton in an atom.
一定要写in an atom，要不然拿不到满分

谢谢讨厌道德的数学神代劳。

本來......SPM的叫你解釋含義的只有F4和F5的syllabus~

但是預備班到中五多多少少一定會出在選擇題的

要醒醒哦~去年SPM华语有简答题要求解释预备班的名句！

谢谢讨厌道德的数学神代劳。

为什么一定要注明“讨厌道德”的数学神
我都说了我不是讨厌咯
要嘛说是不喜欢
我真真讨厌的是历史

anywhere，不必客气，举手之劳而已（之前考试已经把全部defination啃完料）

~梦幻~

這4科我應該是化學較多問題
遲點問

RachelT

討厭歷史的數學神，我來考你一些definition......

1 nucleon number
2 Isotopes
3 ionic bond
4 covalent bond
5 electrolysis
6 electrolyte
7 non-electrolyte
8 concentration(SPM 2006)
9 molarity
10 monoprotic acid
11 diprotic acid
12 salt
13 precipitation
14 alloying
15 polymerisation
16 composite material

大家可以一起來做。 明天公佈答案。

Chemistry分兩組：
easy chapters:
Form 4
2 The structure of atom
3 Chemical formulae and equations
4 Periodic table of element
5 Chemical bonds
9 Manufactured substances in industry
Form5
1 Ra ...

那几课会比较重要（容易拿分 + 会出比较多的）
因为chemistry不太好，要我一课一课读是来不及进脑的了 T___T

稍微解释下 vasodilation和vasocontricion.为什么heart beat increase 就会有vasodilation?warm condition 又vasodilation ?另外,如果可以请帮我解释oestrogen/progesterone/LH/FSH. oestrogen是 repair/thickening endometrium 和 stimulateFSH,progesterone 是 inhibitovulation,LH promote ovulation,FSH 是stimulate follicle cell develop.我想知道graph of hormone against day 而已.这些hormone如何relate去graph?floating plant.有几种?可以告诉我有什么tissue support them to float 吗?要reason 哦.谢谢解释respiration 那里的 鱼,青蛙的 repiratory system''  ''  locomotion 里的earthworm ,鸟, 鱼和grasshoper. 希望可以仔细的为我解释谢谢.p/s:用form 5 level的英文解释.不要翻译去华语

我认为chemistry difficult subject 是 salt,chemical consumer 和 manufacture in industry.就是说,没有算的chapter就难,除了form 4 chapter 4 and 6

5 electrolysis
6 electrolyte
7 non-electrolyte
8 concentration(SPM 2006)
9 molarity
...

1.sum of proton and neutron found in nucleus
2.isotope is same element which has same number of proton,electron but different of neutron
3.ionic bond is formed when metal react with non metal by donate or receive electron to achieve stable electron arrangement which have strong van der waals force .
4.covalent bond is formed when non metal react with non metal by sharing electron  to achieve stable electron arrangement which have weak van der waals force
5.electrolysis is a process
6.electrolyte is a solution which is used in electrolysis and solution have a strong vander waals force .
7.non electrolyte cant conduct electricity because no free mobile ion due to weak van der waals force
8.concentration 和 molarity有什么分别-.-都是 mol/dm^3
9.monoprotic is acid that only have 1 H+ ion-> HCl
10.diprotic is acid have 2 H+ ion  H2SO4
11.salt有soluble和insoluble.prepare soluble salt by using acid reaction. insoluble salt by double decomposition which is .......................... soluble salt+soluble salt ->Insoluble salt ( percipitate )
12. alloying is combination of metal to improve the metal . strengthen,improve appearance, do not corrode easily .......
13.polymerisation is process which made up of small or repeating unit to join together by covalent bond.
14.composite material is a structure material formed by combining 2 or more material with different physical properties to produce a complex mixture .

谢谢回答我bio问题

@冰麒麟@

奇怪。。这个答案。。怪怪的。。怎么说这个是个process.
这个是电解。。。用electric把metal分开或者分解吧

很多process呀

很多process呀

electrolysis是有很多种process,可以是molten / aqueous .也可以用在industry.haha,就是一个process.
考试出千万不要写is a process 哦,会错的

@冰麒麟@

那你还写process呀

抱歉哦。。。我最會只有那四科，其他的我不是很確定所以不能給你錯誤的資料，我建議你發消息去問看已經念大學的乙劍真人。

Chemistry

Form 4 Glossary

Nucleon number	Total number of proton and neutron in an atom
Proton number	The number of proton in an atom
Isotopes	Atoms of the same element which have the same number of proton but different number of (neutron/nucleon) in the nucleus of the atom .
Ionic bond	Chemical bonds which are formed through the transfer of electrons of metal atoms to non-metal atoms
Covalent bond	Chemical bond formed through the sharing of electrons between two non-metal atom
Electrolysis	The process of (breaking down/decomposing) chemical compound into their constituent electrons using electric current.
Electrolyte	A chemical compounds conducts electric current in a molten state or an aqueous solution and undergoes chemical changes.
Non-electrolyte	A chemicals compounds which cannot conducts electric current .
Concentration (SPM 2006)	The mass of substances that dissolves in 1000cm3 of solution.
Molarity	The number of moles of substances that dissolves in 1000cm3 of solution
Monoprotic acid	1 mol of acid dissociate to produce 1 mol of hydrogen ion.
Diprotic acid	1 mol of acid dissociate to produce 2 mol of hydrogen ion .
Salt	A compound produce when hydrogen ion from an acid is replace by a metal ion.
Precipitation	A reaction that involve the exchange of ions to produce an insoluble salt
Alloying	A process of adding (foreign atom/impurities) with atom of pure metal.
Polymerisation	A process of combining monomers to form a long chain of molecule (polymer).
Composite material	Material that are produced from the combination of two or more different compound.

没有灌水啦在等成绩
我的题目还好啦，也不见得很容易，但也不难咯，中等啦
我已经有两粒A咯
可惜，ICT还差两分就可以拿A了
你老师效率很高下，酱快出成绩哦
我英文老师到现在都还没 ...

恭喜，我也是有2个了马来文又再次意外地拿a
那个是前个星期考的

我86p1才对27还好p2高分94救我
全班最高91，本来我也可以

加油~~~

proton number is the number of protons in a nucleus of an atom

你很会背噢

哇，历史啊，我都不懂会不会pass叻
老师说星期五酱派

Proton number is the number of proton in an atom.
一定要写in an atom，要不然拿不到满分

Cation才是positive charge

谢谢通知~
会pass的2张paper我只会jahiliah而已都可以及格




******请问van der waals force of attraction都可以用在2个bond?[ionic bond&covalent]
那electrostatic force 呢？

还有，我朋友说他写total of nucleon number minus neutron number in an atom，这样写也错咯？[proton number]
