There are 18 columns in the periodic table, each has a group #. Give the group #'s that make up each of blocks
957731
s block = groups 1A & 2A (1 & 2)\n\np block = groups 3A- 8A (13-18)\n\nd block =  groups 1B-8B (3-12)

All you really need to know is what column the element is in.  The first column from the left is +1 and the second column from the left is +2.  Here you have to remember to skip over to column 13, which is +3.  14 is + or -4, 15 is -3, 16 is -2, 17 is -1, and 18 is 0.  Columns 3-12 are metals, and there are usually several small numbers above the symbol on a good table.  They will tell you the charge of the element.  If there are more than one for the metal, the bold one is the most common.\n\nHope this helps and isn't too confusing!

Here's a table:\n___Joan________Peg_____________\n     3.........................1\n     4.........................2\n     5.........................3\n    n+2.......................n

13. And I believe you mean 13 electrons. 13 protons, 22 neutrons, and 13 electrons. The atomic number is the number of protons in the nucleus.

It's all the elements in the d-block of the periodic table. Basically, the group starting from column three to column twelve. These transition metals commonly have many oxidation states and have either partially filled d-orbitals or full d-orbitals (like mercury). They also form complex ions quite readily.\n\nIf all of that doesn't make sense, just remember it's the metals in that "lowered" part in the middle.

s and p are orbitals. They also stand for the diffirenet blocks of the periodic table\nIts how you would show where an element is on the table and the electrons in its shells. for example:\nNitrogen\n1s^2 2s^2 2p^3\nthe first number says which period it is in, the letter is the block, and the power is how many elements into the block that is\n\nThis is a bit confusing hard to teach with just words

in the nitrogen group elements every element has outer orbital configuration as np3. (n is no. of shell) so the answer is three.

a) [O 2-]\nb) [ I - ]\nc) [Na+]\nd) [Al 3+]\ne) [Ni 2+]\nf) [Mg 2+]

a) 36\nb) i just found the answer for b : it is 6 because its a p orbital

It is a table of all the atomic elements and the different building blocks of our world.\nThe periodic table is a table in which the chemical elements are arranged in order of their atomic numbers. With this arrangement, elements with similar chemical properties and electronic structures are displayed as vertical columns of the table.

First you need to know the charge of the substances. All  elements in the same group A column have the same charge.\n\nAlkali metals (group 1A) have a charge of +1.\nAlkaline earth metals (group 2A) have a charge of +2.\nMetals from group 3A have a charge of +3.\nHalogens (group 7A) have a charge of -1.\nNonmetals from group 6A (chalogens) have a charge of -2.\n\nNow that you know the charges you can form ionic compounds. The elements must be combined such that the sum of all the charges on th compound is zero.\n\n1. (Alkali metal)+ and (halogen)- \nThe +1 charge on the alkali metal and -1 charge on the halogen sum to zero so they have no subscripts.\n\n2. (Alkali metal)+ and (group 6A nonmetal)2-\nFor the charges to sum to zero, you need two positive charges. So the subscript on the alkali metal is 2 and the group 6 nonmetal has no subscript.\n\n3. (alkaline earth metal)2+ and (halogen)1-\nFor the charges to sum to zero, you need two negative charges. So the subscript on the halogen is 2 and the alkaline earth metal has no subscript.\n\n(alkaline earth metal)2+ and (group 6A nonmetal)2-\nThe +2 charge on the alkaline earth metal and -2 charge on the 6A nonmetal sum to zero so they have no subscripts.\n\n4. (group 3A metal)3+ and (group 6a nonmetal)2-\nFor the charges to sum to zero, you need 6 negative charges and 6 positive charges. To get 6 positive charges, multiply the 3+ by 2. To get 6 negative charges, multiply the 2- by 3. So the subscript on the 3A metal is 2, and the subscript on the 6A nonmetal is 3.

Take the number of red blocks and divide by the total number of blocks.\nnumber of red = 18\nTotal number of blocks = 27+18+12+43 = 100\n18/100\n= 9/50

I'm not really sure what you mean, but here's a good site to look at the periodic table.\n\nhttp://en.wikipedia.org/wiki/Periodic_table

Yeah - its in the second group of the periodic table therefore the ion will be 2+\n\nSome more information which may aid understanding or may just be useful at some stage \n\nAn atom in group one will have an ion which is +1\nAn atom in group 7 will have an ion which is -1\nAn atom in group 6 will have an ion which is -2\nThey are the general rules for all the ions which you you will probably come across most often
