Pakistan Employees Cooperative Housing Society (PECHS), Block 6 is a neighborhood in Karachi East district of Karachi, Pakistan. It was founded by Mehmood Ahmad Nizami in the year 1950, three years after Pakistan was founded by Quaid-e-Azam Mohammad Ali Jinnah. Nizami lived in the same society and also created the first house in PECHS, Block II where some of his descendants now live. It was previously administered as part of Jamshed Town,[1] which was disbanded in 2011.
There are several ethnic groups including Urdu Speaking, Baltis, Punjabis, Sindhis, Christians, Kashmiris, Seraikis, Pakhtuns, Balochis, Memons, Bohras and Ismailis.
Over 98 percent of the population is Muslim with small Christian, Hindu, and other minorities.

A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term seems to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-block, p-block, d-block, f-block and g-block. The block names (s, p, d, and f) are derived from the spectroscopic notation for the value of an electron's azimuthal quantum number: sharp (0), principal (1), diffuse (2), and fundamental (3). Succeeding notations proceed in alphabetical order, as g, h, etc., though elements that would belong in such blocks have not yet been found.
The octet rule is a chemical rule of thumb that describes the strong tendency for main-group elements to bond in such a way that each atom has eight electrons (an "octet") in its valence shell, giving it the same electronic configuration as a noble gas atom. Electrons shared between two atoms in a covalent bond, are counted toward the octet of each atom. The rule is especially applicable to carbon, nitrogen, oxygen, and the halogens, although more generally the rule is applicable for the s-block and p-block of the periodic table. Other rules exist for other elements, such as the duplet rule for hydrogen and helium, and the 18-electron rule for transition metals. For example, the valence electrons in a molecule of carbon dioxide (CO2) can be visualized using a Lewis electron dot diagram. In carbon dioxide each oxygen shares four electrons with the central carbon, two (shown in red) from the oxygen itself and two (shown in black) from the carbon. All four of these electrons are counted in both the carbon octet and the oxygen octet, so that both atoms are considered to obey the octet rule.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
