The molecular orbitals are labelled according to their symmetry, [e] rather than the atomic orbital labels used for atoms and monatomic ions; hence, the electron configuration of the dioxygen molecule, O 2, is written 1σ g 2 1σ u 2 2σ g 2 2σ u 2 3σ g 2 1π u 4 1π g 2, [39] [40] or equivalently 1σ g 2 1σ u 2 2σ g 2 2σ u 2 1π u 4 3σ g ...
[zn(h 2 o) 6] 2+ ⇌ [zn(h 2 o) 5 (oh)] + + h + Hydrolysis explains why basic salts such as basic zinc acetate and basic zinc carbonate, Zn 3 (OH) 4 (CO 3 )•H 2 O are easy to obtain. The reason for the hydrolysis is the high electrical charge density on the zinc ion, which pulls electrons away from an OH bond of a coordinated water molecule ...
For a metal, zinc has relatively low melting (419.5 °C, 787.1 °F) and boiling points (907 °C, 1,665 °F). [8] Cadmium is similar in many respects to zinc but forms complex compounds. [ 16 ] Unlike other metals, cadmium is resistant to corrosion and as a result it is used as a protective layer when deposited on other metals.

The f-block, with the f standing for "fundamental" and azimuthal quantum number 3, appears as a footnote in a standard 18-column table but is located at the center-left of a 32-column full-width table, between groups 2 and 3. Periods from the sixth onwards have a place for fourteen f-block elements.
This notation is used to specify electron configurations and to create the term symbol for the electron states in a multi-electron atom. When writing a term symbol, the above scheme for a single electron's orbital quantum number is applied to the total orbital angular momentum associated to an electron state. [4]
