what is the id of the component x inside the following ions? what are the likely ground-state electron configuration settings of the following anions N3-: 1s2 2s2 2p6

Se2-: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 5s2 4d4

Recognize the factor whose 2+ ions gets the ground condition electron configuration [Ar] 3d^10 Zinc

Which has the smaller second ionization energy, K or Ca?

CaThree atoms have following electron configuration.

a) 1s2 2s2 2p6 3s2 3p3

b) 1s2 2s2 2p6 3s2 3p6

c) 1s2 2s2 2p6 3s2 3p6 4s2

Which of the three has got the largest Ei2 and the smallest Ei7? N largest Ei2

C tiniest Ei7

Which in turn element in all the following units has the tiniest first ionization energy, which includes the largest? 1) Li(L), Purse, K(S)2) B(S), Be, Cl(L)3) Ca(s), C, Cl(L) Order the following compounds according for their expected essudato energies: LiClKClKBrMgCl2

MgCl2> LiCl> KCl> KBr Ranked by Smallest substances have the major lattice energy. calculate the complete energy difference in kilojoules every mole pertaining to the formation of CsF(s) from the elements making use of the following info: Eea intended for F(g) sama dengan -328 kj/mol, Ei1 for Cs(g) = +375. several kj/mol, temperature of sublimation for Cs(s) = +76. 1 kj/mol, bond dissociation energy for F2(g) sama dengan +158 kj/mol, lattice strength for CsF(s) = +740 kj/mol which of the subsequent substances are largely ionic and which can be covalent HF ENF sama dengan 4. 0; ENH sama dengan 2 . 1: DEN = 1 . being unfaithful HF is polar covalent.

(b) HI ENI = 2 . 5; ENH sama dengan 2 . 1: DEN = 0. 5 HI is definitely polar covalent. (c) PdCl2 ENCl sama dengan 3. zero; ENPd = 2 . two: DEN = 0. almost 8 PdCl2 is polar covalent. (d) BBr3 ENBr sama dengan 2 . almost eight; ENB sama dengan 2 . zero: DEN sama dengan 0. almost eight BBr3 can be polar covalent. (e) NaOH Na+-OH- is definitely ionic

(f) CH3Li CH3Li is extremely covalent.

Use the electronegativity data in Figure 7. 4 to predict which will bond in each of the next pairs is more polar. (a) C-H or C-Cl Particular DEN's: zero. 4 & 0. five C-Cl is far more polar(b) Si-Li or Si-Cl Respective DEN's: 0. almost 8 & 1 . 2 Si-Cl is more polar. (c) N-Cl or N-Mg Respective DEN's:...
