The three dots around Al's Lewis structure represent Al's unpaired valence electrons.
the nucleus in the middle with 11 protons and 12neutrons, then there are three surrounding shells - the first with 2 electrons, the second with 8 and the third with 1 there are 12 neutrons...
It looks like thisK–Br:except that there are also two dots both above and below the "Br" in the diagram (there are three lone pairs on Br, and none on K)See the Related Questions link about Lewis Dot Structures to the left of this answer for more help with electron dot diagrams!
Chlorine has 7 valence electrons, as well as Flourine. Add both 7's together to get the total # of electrons which is 14. Draw the symbol for both elements and fill in the dots and or dashes as you go along. it is a single bond so put a dash between both symbols and that represents 2 electrons so each needs 6 more electrons so then put the dots needed around both elements. There should be 6 dots around each element and a line connecting the two. -Hope this helps(: (Current high school chemistry student who finally understands how to do this herself!)
AnswerI am not sure of the exact numbers of dots, and crosses, however if ammonia can form only three bonds, then the folliwing is correct:sorry had drawn image in paint but can'y put it in lol stupid moderators. So draw one circlethen overlap three other circles with it, none touching each otherthen label the centre 'N'and the others 'H'and put a dot and a cross in each overlapping section(there should be three dots and three crosses in the whole diagram------------------------------------------------------------------------[EDIT] Actually the formula for an ammonia ion is NH4+ Due to dative bonding the 4th hydrogen loses an electron making it a positive ion and allowing it to form a dative bond with the Nitrogen. Meaning the nitrogen donates 2 electrons to this 4th hydrogen, completing it's shell.The diagram would be an N in a circle then 4 circles around it overlapping. A dot and a cross in 3 of them and then 3 dots in the final circle.
K* *******I (draw the 7 electrons around the I, i cant because im typing, obviously) [K]+-->[********I]- you write + for K because it has lost an electron (and therefore has a charge of 1+) and - for I because it has gained an electron ( and has developed a charge of 1-) this is an ionic bond hope it helps:)

Simply draw 3 rows of three dots to show that the dots form a square, as shown below:. . .. . .. . .
This is the sequence of triangular numbers. You draw one dot. Then you draw two dots in the line below - one to the left and one to the right of the first dot. You now have a triangle, of three dots. Then you draw three dots in the next line and you get a triangle with 6 dots. Next, four more dots in the next line giving a triangle with 10 dots. The name is easy to understand if you can visualise or even actually draw these dots. It is difficult to demonstrate through an ordinary word processing package.
first circle draw 2 dots. second circle draw 8 dots third circle draw 10 dots!
Br Then draw two dots like .. above and below its chemical symbol. Then draw two dots like : to the left of it. Then draw a single dot like . to the right of it. In summary, it should be the chemical symbol, with seven dots around it in groups of two where possible. Group 7 element, so 7 valence electrons to draw. *Can also use crosses like x and xx.
Draw a line from one dot in the center to the other four dots. Or, draw a straight line. Place dots at either end of the line, and place dots in the center of the line.
you line up the dots of the segment to the dots of the protcractor and draw/measure the angles.
Argon has 18 electrons. Draw a circle in the middle with the chemical symbol of argon in it (Ar). Draw three more circles around the middle one. On the first circle draw 2 dots to represent electrons. On the 2nd circle, draw 8 electrons. And finally, on the last circle, draw another 8 electrons. That is the bohr-rutherford diagram of argon.

you draw two circles beside each other and then put three dots in them then you make a triangle above the circles then draw a loop for the tongue and then draw half a circle from one circle to the other then draw some eyes and make some ears.
it is like an oval with dots in
