Determine the element that is not correctly described

	A.	Ti is a d-block element that has two 3d electrons
	B.	Ar is a second period monoatomic gas
	C.	S is a p-block element with four 3p electrons
	D.	The first ionization energy of Na is lower than the first ionization energy of Mg
	E.	I is a group-7 element, and exists as a solid at room temperature

Expert Solution

B. Ar is a second period monoatomic gas.

Argon belongs to 18_th group of the periodic table.

Argon belongs to 3_rd period of the periodista table.

Argon belongs to p-block of the periodista tablle.

period Number	Elements of 18_th group
1	Helium
2	Neon
3	Argon
4	Krypton
5	Xenon
6	Redon
7	Ununoctium

Which statement most correctly describes crystal field theory for a d-block complex of unspecified geometry

Which statement most correctly describes crystal field theory for a d-block complex of unspecified geometry а) The theory considers covalent interactions between a metal center and surrounding ligands. b) The theory considers electrostatic interactions between a metal ion and the surrounding ligands which are taken to be point charges c) The theory rationalizes the non-degeneracy of the metal d orbitals by considering the electrostatic repulsions between point charge ligands and electrons in the metal d orbitals d) The theory rationalizes why the metal d...

An ideal gas described by Ti = 300 K, Pi = 2.00 bar, and Vi = 15.0 L is heated at constant volume until P2 = 20.0 bar. It then undergoes a reversible isothermal expansion until P3 = 2.00 bar. It is then restored to its original state by the extraction of heat at constant pressure. Depict this closed-cycle process in a P-V diagram. Calculate number of moles n ( two decimals, as 3.21) = [n]; V2 (unit L, no...

One mol of an ideal gas described by Ti = 300 K, Vi = 2.46 L, and Pi = 10 atm undergoes isobraic expansion (constant pressure) until V = 5 L. Next, it undergoes a reversble isothermal (constant temperature) expansion until P = 1.00 atm followed by isobaric compression to T = 300 K. Finally, it is restored to its original state by reversible, isothermal compression. a) Depict this cyclic process on a P-V diagram. b) Calculate w, q, deltaU,...
