What is a Lewis Dot Structure?
A Lewis dot structure is a type of shorthand notation used to represent the electron configuration of an atom or molecule. It is named after American chemist Gilbert N. Lewis, who introduced the concept of electron pairs in 1916.How to Draw the Lewis Dot Structure for NOCL?
The Lewis dot structure for NOCL is drawn by first placing the symbol for nitrogen (N) in the center. Around the nitrogen atom, four dots are drawn to represent the four valence electrons. The oxygen atoms each have six valence electrons, so six dots are drawn around each of them. The chlorine atom has seven valence electrons, so seven dots are drawn around it. The resulting Lewis dot structure should look like this:N . . . O . . . O . . . Cl
Questions and Answers:
1. Write the Lewis dot symbol for magnesium and chlorine atoms.
Jawaban:
mg forms ionic bond to Cl by donating its valence electrons to two Cl atoms . The electron configuration of Mg is [Ne]3s². It can achieve a complete octet by losing its components
2. gambarkan struktur dot lewis dari senyawa NHl

3. Tuliskan rumus dot-lewis untuk NH3 dan OH-
Jawaban:
OH- tidak memenuhi kaidah oktet dikarnakan hanya terdapat 7 elektron saja.
Penjelasan:
Rumus NH3 :
N : 25 memiliki 5 elektron valensi (N3-)
H : 1 memiliki 1 elektron valensi
Rumus OH :
O : 26 memiliki 6 elektron valensi (O2-)
H : 1 memiliki 1 elektron valensi
OH bernilai -1

6. Which structure is responsible for reproduction in angiosperms?
Jawaban:
Conclusion: Flowers and fruit, two unique reproductive systems, are responsible for angiosperms' success. The flower's purpose is to ensure pollination. Flowers also shield the developing embryo and ovule inside the receptacle.
7. Dengan menggunakan teori asam basa Lewis, tunjukkan bahwa reaksi berikut merupakan reaksi asam -basa dengan menggambarkan dot elektronnya: BF3 + F - (aq) BF4
BT3 adalah molekul dengan atom intinya telah stabil(pada atom pusat tidak terdapat pasangan elektron bebas)sehingga ketika direaksikan dengan atom F maka Terjadi reaksi kovalen koordinasi koordinasi di mana elektron yang berasal dari atom F digunakan bersama hal ini berarti atom F sebagai donor elektron jadi yang bertindak sebagai basa adalah F.

8. structure for comparison adverb
Jawaban:
We use comparative adverbs when talking about two actions (not three or more actions). Comparison is always between TWO things.
How do we Make Comparative Adverbs?
There are three basic ways to make or "form" a comparative adverb:
1. One-syllable adverbs: add -er
If an adverb has only one syllable, we usually just add -er to make it comparative: fast → faster. Here are some examples:
adverb comparative adverb
fast faster
hard harder
high higher
late later
long longer
low lower
wide wider
Note that most one-syllable adverbs have the same form as their equivalent adjectives. Don't let this confuse you. For example:
positive comparative
adjective a fast car a faster car
adverb he drives fast he drives faster
2. Two-syllable adverbs: use more
When an adverb has two or more syllables (like all -ly adverbs), we can make it comparative by adding more in front: quickly → more quickly. Look at these examples:
adverb comparative adverb
carefully more carefully
efficiently more efficiently
happily more happily
horribly more horribly
often more often
quickly more quickly
recently more recently
slowly more slowly
sadly more sadly
strangely more strangely
We can also use less in place of more to suggest a reduction in the action. Look at these examples:
sentence for example
She visits often. once a week
Now she visits more often. ↑ once a day
Now she visits less often. ↓ once a month
3. Irregular Adverbs
A few adverbs have irregular form, for example:
adverb comparative adverb
badly worse
early earlier
far further/farther
little less
much more
well better
Comparative Adverbs with Informal Forms
Note that a few adverbs have a formal ("correct") form with -ly and an informal form without -ly. The same is then true of their comparative forms. Although you may hear some native speakers using the informal form in speech, it is best avoided in formal situations and examinations. The most common examples are:
adverb comparative adverb
cheap/cheaply cheaper/more cheaply
loud/loudly louder/more loudly
quick/quickly quicker/more quickly
slow/slowly slower/more slowly
Note that a few adverbs have NO comparative form, for example:
again, first
daily, yesterday
here, there
now, then
never, sometimes
How do we Use Comparative Adverbs?
Now that you know how to make comparative adverbs, let's see how to use them. Look at these examples. Notice that we may use more to suggest an increase in the action and less to suggest a decrease in the action. Notice also that the comparative adverb is often followed by than:
Trains go fast but planes go faster.
Planes go faster than trains.
Trains don't go faster than planes.
Trains go more slowly than planes.
Planes go less slowly than trains.
Joe won because he played better than Jane played.
Joe won because he played better than Jane.
Joe won because he played better.
Did cities grow more quickly after the Industrial Revolution?
He hit the ball more powerfully than his competitor.
As we get older we remember things less easily.
Could you talk a bit more quietly please?
Could you talk a bit less loudly please?
I can't hear you. Please speak louder/more loudly.

PembahasanRumus lewis atau rumus titik elektron merupakan gambaran untuk memudahkan dalam menjelaskan ikatan ikatan kimia. Menurut Lewis elektron valensi suatu usnur dapat digambarkan dengan menggunakan tanda ( о ) atau ( x ) . Titik yang digambarkan pada struktur lewis tersebut merupakan jumlah elektron valensi. Elektron valensi adalah elektron yang berada pada kulit valensi (kulit terakhir). Valensi merupakan bilangan yang menyatakan jumlah pasangan elektron ikatan yang dapat dibentuk oleh atom pusat, atau jumlah atom yang diikat oleh atom pusat.
