...magnetic field of strength 0.069T pointing e? An electron travelling north with a speed of 8.9x10^6m/s enters a magnetic field of strength 0.069T pointing east.
(a) what is the radius of the electron's orbit?
(b) in what plane (upward and north-south, upward and east-west, or horizontal)...
Is there a specific way to remember this?

I don't get what you are talking about, can u give some examples?
It was only two years ago that IBM showed us an image of a complete molecule, atomic bonds and all, but today's news does that one infinitesimally-sized breakthrough better. Ladies and gents, behold the first image of an electron's path. More »
...figure out why my answer's wrong? wavelength = h / mu, right?
h = 6.63*10^-34
mass of an electron (m) = 9.10938188 × 10^-31
velocity (u) = 1.03*10^5
(6.63*10^-34) / (9.10938188 × 10^-31)*(1.03*10^5)
= 74.99
so why does my answer come up wrong? any help at all would be appreciated. i'm lost...
What are the observed periodic trends in electron affinity?
Check all that apply.
1.) for main-group elements, electron affinity generally becomes more negative as you move to the right across a row
2.) for main-group elements, electron affinity generally becomes more positive as you move to...
Ive browsed the net and i cannot find the electron affinity trend in period 3 elements.
I don't want to know 'how' the trend works, i need the actual numbers - thankyou!
Electron affinity increases in the periods across the p block. An exception to this trend occurs between groups 14 and 15.
Ex: compare the the EA's of C ([He]2s2 2p2) and N ([He]2s2 2p3). Adding an electron to a C atom gives a half-filled p sublevel. This occurs much more easily than forcing an...

I know this question is relatively straight forward, but when i try to submit the answer, the program I'm using keeps telling me it's incorrect. I used the formula Lambda = h/mv :
(6.62600 * (10^(-34))) / ((9.10900 * (10^(-31))) * (1.14 * (10^5))) = 6.38081096 × 10-9
Can someone pleeease tell...
CH3-?...multiple choice given...? According to VSEPR model, what is your prediction for the arrangement of electron pairs for CH3-?
Choose one answer.
A. tetrahedral
B. linear
C. trigonal planar
D. bent
Please dont guess...thankss..:-)
A table lamp is connected to an electric outlet by a copper wire of diameter .20 cm and length 2.0m. Assume that the current through the lamp is 1.5A, and that this current is steady. How long does it take an electron to travel from the outlet to the lamp?
My classmates and I are sick of constant lecturing, so the teacher said he would be willing to try something new out, if we had a good proposal for a "more exiting" class, but I'm not very experienced in Biology, so please could you help me out? Thanks!
stops midway? Hi, I am reviewing for a test next week and have no idea what section this would be under.
Two electrons are fixed 2.0 cm apart. Another electron is shot from infinity and stops midway between the two. What is its initial speed in m/s?
I wish I knew how to get started, but I...
