Can someone xplain the priodic table to me?
Q. xplain all the different groups found in it and what the boxes mean? Also I need to know what the s,p,d,f blocks mean. Finally i need to know the chemical series of it like alkali metals... where theyre found and what they need! I really need help. Any help is fine! Ty fot ur time an help :D

A. okay . to start off . each box represents a different element . the big letters are its symbol . ex . Salt NA - the number that is usually uneven [ex/21.414] is the atomic mass .which means the number of protons plus the number of neutrons . the other number that is usually liek just 21 say is the number of protons the object has . it is also the number of electrons it has . to find the number of neutrons . ull subtract the uneven number [round it off to the nearest whole] from the even number to find the neutrons . now . take the number of electrons [even number] and watever group its in is the number of electrons it has in its valance shell . say its in group 6 . it has 6 electrons in its valance shell which is where the spdf come from .… [cont.]

Difference between hybrid orbital and hybridization?
Q. On an assignment the instructions for one part state to decide the type of hybrid orbital of the central atom and then the next part says to indicate the type of hybridization of each atom in a molecule. Do these two mean the same? Stating s, p, d, f?

A. I'd say the same. Nit-picking, one is process and the other is outcome, but that doesn't affect how you answer.

Quantum numbers and orbitals?
Q. I have 3 questions about using quantum numbers and orbitals. I'm doing a take home test and I don't understand how to get some of the answers. the first one asks 1) when n=3 the possible values of L are? I got 0, 1, 2 but I don't understand the reasoning behind this. I know sometimes that you can get negative numbers so I don't know if this answer is right. 2) what type of orbital corresponds to L=1? I know L describes the shape, so this means to use the s,p,d,f orbital thing. 3) for a d-subshell what are the possible values of m1. I don't quite get what m1 refers to in general. We went over it in class, but not alot because we have finals coming up and had other stuff to go over. I think m1 is the one that I was talking about having… [cont.]

A. 1) The angular momentum quantum number can have values from 0 to n - 1. If n = 3, then the angular quantum number, l ("el") can have values of 0, 1, and 2. 2) The angular momentum quantum number, l, describes the general shape of an orbital. When l = 1, it represents a p orbital. When 1 = 0, it is an "s" orbital; 1 is a "p" orbital; 2 is a "d" orbital; and 3 is an "f" orbital. All "s" orbitals are spherical in shape; "p" orbitals are dumbell-shaped; "d" orbitals are multi-lobed; and "f" orbitals are even more complex and multi-lobed. 3) The magnetic quantum number, in general, describes the number of directions in space that the orbitals point. The permissible values of the magnetic quantum number, m, are integers from - l to + l. For… [cont.]

can anyone help me plzzzz 10 points?
Q. i totally don't understand the principal of quantum numbers...and the atomic orbitals...what the hell do they mean by different ENERGY levels and the s,p,d,f orbitals...can you explain each one plzzz like in the p orbital why are there y,x,z wings things...can you plzz paint a picture of this in my head please ...i kw am asking for alot but i have an exam soon thank you

A. Electrons occupy space in an atom and are organized energy levels and orbitals. There are Main levels 1, 2, 3 and 4. Then there are Sub levels s, p, d, and f. In the first energy level, there is the s sublevel. In the second energy level, there is the s and p sublevels and so on.. Each sublevel holds a number of electrons. s = 2 electrons p = 6 electrons d = 10 electrons f = 14 electrons Main Energy Level -> Sub Level (orbitals) -> no of electrons 1 -> 1s -> 2e max 2 -> 2s, 2p -> 2e + 6e = 8e max 3-> 3s, 3p, 3d -> 2e + 6e + 10e = 18e max 4 -> 4s, 4p, 4d, 4f -> 2e + 6e + 10e + 14e = 32e max think of it like an apartment building with 4 floors (main energy levels), and each floor has rooms on… [cont.]

I really need help on my chemistry homework!!!?
Q. Electron Configuration Worksheet (and Lots More!!) Brief Instructions An electron configuration is a method of indicating the arrangement of electrons about a nucleus. A typical electron configuration consists of numbers, letters, and superscripts with the following format: 1. A number indicates the energy level (The number is called the principal quantum number.). 2. A letter indicates the type of orbital: s, p, d, f. 3. A superscript indicates the number of electrons in the orbital. Example: ls2 means that there are two electrons in the s orbital of the first energy level. The element is helium. To write an electron configuration: 1. Determine the total number of electrons to be represented. 2. Orbitals are considered to be in the… [cont.]

A. I had the same problems. s obitals can hold no more than 2 electrons. p orbitals can hold 3 therefore they can hold 3-6 d orbitals can hold 5 therefore they can hold 5-10 Write out the orbital triangle. 1s 2s 2p 3s 3p 3d 4s 4p 4d 4f 5s 5p 5d 5f 6s 6p 6d 7s 7p The order of the eletrons go diagonally down the triangle starting at 1s (example) 1s 2s 2p 3s 3p 4s etc. So the configuration depends on the element. (example) carbon's atomic mass is 6 The electron configuration is 1s(to the second power)2s (to the second power)2p(to the second power). If you notice if you add all the powers together they equal 6. I hope this helps. I had trouble with this at first. If you need more help this website helped me.
