Select an answer for each of the following. Na+ Ti2+ P Te2- O C

Select an answer for each of the following. [Note: You may use an answer more than once.]

Na⁺Ti²⁺ P Te²^-O C

Has the largest ionic radius
Neutral atom with the largest first ionization energy
Is isoelectronic with Ne
Has 3 unpaired electrons
Has an electron configuration of [Ar] 3d²
Neutral atom with the largest effective nuclear charge

Expert Solution

Te2- has the largest ionic radius- being in the fifth period already have five shells and by accepting two electrons the size is further increased.
O- atom has the largest first ionization energy- Due to small size electrons are held strongly with nucleus

Na+ is isoelectronic with Ne- As neutral na has 11 electrons, Na+ after losing one electron have 10 electrons like Ne

P has 3 unpaired electrons- The electreonic configuration of P is [Ne].3s2.3p3 . It has one unpraired electron in p-orbitals

Ti2+ has an electron configuration of [Ar].3d2-The actual configuration of Ti is [Ar].3d2.4s2but on losing 2 electrons of s-orbital it become Ti2+.

O-atom has the largest effective nuclear charge-

2- a) Assume the following concentrations of Na+ and K+ ions: [Na+]o = 120 mM, [Na+]i = 6 mM, [K+]o = 2 mM, and [K+]i = 150 mM. Assume further that at the peak of the action potential, pK : pNa is 1 : 12. Calculate Vm at the peak of the action potential.(Use Goldman-Hodgkin-Katz equation, disregard Chlorine ion) b) Explain the molecular basis of the neuronal refractory periods. That is discuss both the absolute refractory period and the relative...

Sodium azide (NaN3) can decompose at 300 o C to produce sodium metal (Na) and nitrogen gas (N2). This is one of the key reactions in an automobile air bag. The balanced equation for this reaction is: 2NaN3(s) →2Na (s) + 3 N2(g) Part A If 0.189 mol mole of NaN3 is completely decomposed at 300.0 o C and 1.00 atm, what volume (in L) of nitrogen gas would be produced? Express your answer using the correct number of significant...
