Orbit and orbitals.........................


orbit:
1. well-defined circular path followed electron around nucleus.
2. represents 2 dimensional motion of electron around nucleus.
3. maximum no. of electrons in orbit 2n2.
4. orbit circular in shape.
orbital:
1.it region of space around nucleus probability of finding electron maximum.
2. represents 3 dimensional motion of electron around nucleus.
3. maximum no. of electrons in orbital 2.
4. orbitals have different shapes.


atomic orbitals differ in shape. is, electrons describe have different probability distributions around nucleus.
s orbitals spherically symmetrical. is, electron occupies s orbital can found same probability @ orientation (at given distance) nucleus. these orbitals therefore represented spherical boundary surface , surface captures high proportion of electron density. electron more found somewhere inside spherical boundary surface outside.
p orbitals double-lobed, region of high electron density on each side of nucleus. boundary surface of p orbital therefore consists of 2 lobes projecting nucleus. 3 p orbitals of given shell designated px, py, or pz according alignment of lobes along 1 of 3 mutually perpendicular axes.

what difference between orbit , orbitals? , why shape of s orbita different p orbital?

Connections Academy...?

trying go connections academy because of bullying has been going on since second grade. have created presentation, sent multiple emails, printed handouts , packets, , have had family come on discuss issue well....however, mom doesn't focus on initiative taking of information up. completely, 100% against connections academy because feels isn't normal school kids attend , if don't go high school, won't have "high school experience." understand many of disagree persistence on topic. however, bullying hurtful when in situation in , have bad anxiety backfiring.... unfortunately, mom feels private or charter school better option don't think eliminate bullying, many teenagers relatively bullying regardless. instead of allowing me attend connections academy, mom wants other options find insulting , unnecessary because can fixed through online school instead of dealing problem other people causing. example, mom researching physiologists, anti-...
