Best ResponseYou've already chosen the best response.1lets look at the QM numbers one at a time

Best ResponseYou've already chosen the best response.1the first one is n ; the principal QM, it represent the electron shell n has to be some positive natural number

Best ResponseYou've already chosen the best response.1all the n's in the options are valid

Best ResponseYou've already chosen the best response.1the second QN , \(\ell\); is the subshell this can be values from 0 up n1

Best ResponseYou've already chosen the best response.1this makes of two of the options invalid, can you tell me which two?

Best ResponseYou've already chosen the best response.1Yes the options have the second term: either not greater than 0, or not less than n so they can't be right

Best ResponseYou've already chosen the best response.1we have these options left: (1, 0, 0, +½) (3, 2, 3, ½)

Best ResponseYou've already chosen the best response.1the third quantum number is the magnetic quantum number, \(m_\ell\) this can be any integer less than or equal in magnitude to \(\ell\) _____ for example if \(n\) was 5 and \(ell\) was 4, \(m_{\ell}\) could be 4, 3, 2, 1, 0 , 1, 2, 3, or 4

Best ResponseYou've already chosen the best response.1The final quantum number is related to the spin of the electron, \(m_s\) this can only take values of: \(+\tfrac12\) or \(\tfrac12\)

Best ResponseYou've already chosen the best response.1Only one of the options has both: the second QN less than the first (but nonnegative), and the third QN less than or equal to (in magnitude) the second

Best ResponseYou've already chosen the best response.1Which option is this @tywower?

UnkleRhaukus

Best ResponseYou've already chosen the best response.1nope, the third option has the third QN greater than (in magnitude) the second QN

Best ResponseYou've already chosen the best response.0can u explain why it's the second one :)

Best ResponseYou've already chosen the best response.1A. (1, 1, 0, +½) not this one, \(\ell\not<n\) (1, 0, 0, +½) maybe (3, 2, 3, ½) not this one, \(m_\ell\not\leq \ell\) (3, 1, 0, ½) not this one either, \(\ell\not>0\)

Best ResponseYou've already chosen the best response.0Such as: Which of the following pairs of elements could possibly be found in the same group on the periodic table? A is an alkali metal, B forms a 1 ion. A has the atomic number 20, B forms a 2 ion. A is a noble gas, B has seven valence electrons. A forms a 3 ion, B has five valence electrons.

Best ResponseYou've already chosen the best response.1What kind of ions do metals form? + or  ?

UnkleRhaukus

Best ResponseYou've already chosen the best response.1so could the first option possibly be true?

UnkleRhaukus

Best ResponseYou've already chosen the best response.1elements in a group (column) always form the same kind of ions e.g. Mg^+, Ca^+, are ions of group II, F^, Cl^, Br^, are ions of group VII

Best ResponseYou've already chosen the best response.1If A and B are of the same group, and A (a metal) forms ^+ ions, could B form ^ ions?
