An electron in an L shell of an atom has the principal quantum number:
A. n = 0
B. n = 1
C. n = 2
D. n = 3
E. n = ∞
A photon with the smallest wavelength in the continuous z-ray spectrum is emitted when:
A. an electron is knocked from a K shell
B. a valence electron is knocked from the atom
C. the incident electron becomes bound to the atom
D. the atom has the greatest recoil energy
E. the incident electron loses all its energy in a single decelerating event

Light from any ordinary source (such as a flame) is usually:
A. unpolarized
B. plane polarized
C. circularly polarized
D. elliptically polarized
E. monochromatic

Guys proff that p=1/3Nmv2



And 1/2mv2=3/2kt

What the name of the alkane used in infrared experiment

Guys explain why ZnS is not ionic in nature

Oga sammy what of 50 for microbiology

Obiagelli: @ sammy329, my brother has a composite of 49.6 for micro biology, is it good enough

me too microbio my composite is 49.975

na prayer sure pass o

Moyour1: [color=#990000][/color] even though my chances ar pretty slim 4 dis admission, i'm still not gonna give up on God., Cos He's Brought Me Too Far 2 Leave Mi Now! 'thr's no crime in hoping'

yes boss

Bomooba.com:
pls i had 24% in putme n ma total composite is nw 40.49% n am going in 4 forestry n wildlife mgt 1st choice any hope...pls yes / no

yes if Oluwa is involved

Zikdik: Please,what is my composite score.UTME-226,PUTME-66%,O-LEVEL-Maths-C6,English-B3,Biology-C4,Physics-B3,Chemistry-C6.
Applied to study Microbiology.

me too microbiology 64% in pume 195 jamb c5c6c5c6c4...

Mcb aspirant drop ur composite

64 percent. Thank God o

Negative electrons were are found so close to the nucleus,why are they not pulled into the nucleus by d positive charge of the nucleus??

All is well






Oluwa is involved.

Abbeylec: do u still remember d qx if so reitrate so we can knw d actual ans cos if I culd remember, I was asked abt d bacteria dat provide nitrogen nd d ans is nitryfing bactetria nd nt nitrogen fixing bacteria because nitrogen fixing bacteria turns nitrogen into ammonia

ok sowi bro different question

my questn was which of the following bacterial convert nitrogen to nitrate...
*wink*

Whats magnetic moment ?

Dr T.I:
I thank GOD 4 2day exams..bak *home swit home*...#result on my mind

which course?

micmay: oga d ansa is not civil,opposite in meaning of militant is nt civil.

abi oo

Abbeylec: its nitrifying bacteria nt nitrogen fixing bacteria

no na nitrogen fixing bacterial

Phemmy99: To those who have written d putme,,,one thing u should know is dat "Your level of input is not always directly proportional to your level of output",,,You just have to keep praying evn if you are sure of what you did....#Calculus..

yes boss: trust in God with all thine heart and not lean on thine own understanding prov3:5

boss saprophytic not holophytic
not protein but protein and fat&oil .

Kunlexic: the azimuthal quantum no shows the energy sub-level in each shell(i.e- s,p,d,f) while the principal quantum shows d shells/energy level(i.e-K,L,M,N shells)

yes boss

Am in

Whats the difference btw azimuthal and principal quantum number??
