WHAT CAUSE AN ELECTRON TO OCCUPY A HIGHER ORBIT?? Do you really mean an electron or are you really referring to a planet or satellite since the title of your post is astronomy? If you really meant a planet or satellite: Consider a satellite in a circular orbit around the earth...

chem please explain to me!
can someone please elpain to me the formation of binary ionic compounds from its constituent element. cuz I don't understand! thanks I really thank you guys alot! What grade are you in? Do you know about s and p orbitals? um.. why does it matter??? and I don't get the whole ...

I have to fill in the blank with the a term, short phrase or number The Blank describes the sequence in which orbitals are filled. Is it The Pauli exclusion principle?? No. The Pauli exclusion principle states that no two electrons may occupy the same energy position. What is ...

Chemistry Electron Configuration Questions
I do not understand anything about electron configuration. How do you figure out if the element is in P,D,S,orF? What do the subscripts represent? What is a subshell? I am so confused!! You figure it out by using the Aufgau principle, placing electrons in the proper order in ...

I'm supposed to find the quantum numbers for a 5py orbital. I'm not sure how to do this, can anyone help? N=5 l = 4 3 2 1 0, for p you want l = 1 ml= -1 0 +1 representing px, py, and pz orbitals. ms= +1/2 and -1/2. Look at a diagram in your book for the px, py, and pz orbitals...

Chemistry - Hybridization
Can anyone help me with this questioin pleasee? Describe the orientation and relative energy levels of sp2 and sp3 orbitals with respect to unhyberdized orbitals (1s, 2s, 2px, 2py, 2pz orbitals) 1s and 2s are spherical. 2px, 2py, and 2pz are at 90o to each other (mutually ...

how does a hydrate form? Generally water adds to a metal ion to the d,s, and or p orbitals in which the metal acts as a Lewis acid. I can reword that somewhat if you haven't studied about Lewis acids.

How many electrons can occupy a single molecular orbital? and Alumimum is a group 3A metal, Which ion does A1 typically form? I'm thinking Al3+ Your first question depends on the molecule involved and how it is bonded. Hybrid molecular orbits can be formed. Now in an atom, ...

I am really confused on hybridization and how to do the orbital drawings. For example for BeF2: The electron configuration of F is (1s^2)(2s^2)(sp^5). In my book it says that there are two electrons in the ground state of Be in 1s and 2s orbital shells. For B3, 1 electron from...

Chemistry Periodic Trends
The electron affinities of the elements from aluminum to chlorine are -44, -120, -74, -200.4, and -384.7 kJ/mol respectively. Rationalize the trend in these values. Electron affinity is the energy absorbed (endothermic) or emitted (exothermic) by the addition of one electron ...

I really need help on the concept of bonding and antibonding orbitals. I know you use sigma molecular orbitals to use with the antibonding and bonding. Can you explain to me how you actually use them with the sigma molecular orbitals and what purpose they have? I'm confused on...

General chemistry ligand
Hello. I have a question about ligands. How do you figure out how many ligands a central metal cation can have? For example, Cu^2+ and NH3. When they combine, it forms Cu(NH3)4^2+ Why does it form 4 ligands oppose to 6? A general rule, which isn't always followed, is to double...
