In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table, but the f-block columns (between groups 2 and 3) are not numbered. The elements in a group have similar physical or chemical characteristics of the outermost electron shells of their atoms (i.e., the same core charge), as most chemical properties are dominated by the orbital location of the outermost electron.
There are three systems of group numbering. The modern numbering group 1 to group 18 is recommended by the International Union of Pure and Applied Chemistry (IUPAC). It replaces two older naming schemes that were mutually confusing. Also, groups may be identified by their topmost element or have a specific name. For example, group 16 is variously described as oxygen group and chalcogen.
CAS and old IUPAC numbering
Two earlier group number systems exist: CAS (Chemical Abstracts Service) and old IUPAC. Both use numerals (Arabic or Roman) and letters A and B. Both systems agree on the numbers. The numbers indicate approximately the highest oxidation number of the elements in that group, and so indicate similar chemistry with other elements with the same numeral. The number proceeds in a linearly increasing fashion for the most part, once on the left of the table, and once on the right (see List of oxidation states of the elements), with some irregularities in the transition metals. However, the two systems use the letters differently. For example, potassium (K) has one valence electron. Therefore, it is located in group 1. Calcium (Ca) is in group 2, for it contains two valence electrons.
In shooting, a shot grouping, or simply grouping, is the placement of multiple shots on a target, the shots taken in one shooting session. The closeness of the grouping, the nearness of all the shots to each other, is a measure of the accuracy of a weapon, and a measure of the shooter's consistency and skill.
Uses of the term
For firearms that shoot one round at a time, a shot grouping can be used to measure the accuracy of the system comprised out of weapon as well as the precision and uniformity of the ammunition by fixing the weapon into position on a test mount, and aiming it at a target. Multiple shots using rounds from same type and batch are fired to observe how the weapon groups the shots. If a person holds the weapon and shoots it, the grouping measures the combination of the person's skill and the weapon's accuracy.
In shotgun shooting, the grouping is also called the pattern. The pattern is the spread of shot from a single shotgun shell, measured as the smallest circle containing all the shots on the target. The barrel of a shotgun is designed to deliver a wide or narrow grouping, depending on the expected use. Shooting at close range indicates a cylinder bore barrel to deliver a wide grouping, while for hunting at longer distances such as 50 yards or meters, a choke is recommended for a tighter grouping.
“We are in the real early innings of the explosion of all things sports and tech, much like where fintech was 10 or 15 years ago,” John Garabedian, a former senior partner at Boston Consulting Group in Chicago who recently joined the fund as a partner, said in a statement.
Instead of stimulating dubious offsets to meet otherwise-unattainable targets, the World Wildlife Fund and Boston Consulting Group suggest companies disclose their emissions, estimate how much they can credibly reduce them, and pledge funding for research into permanent GHG removal.
“As a part of the action plan that HUD has established, Capital Realty Group has committed $3 million in owner funds as part of a renovation plan that is being developed in consultation with the RainbowPUSHCoalition and the Concordia Place Tenant Association for review by HUD.
The Fund was over-subscribed and closed on schedule at its hard cap in about four months after the official launch. Fund III's investors are comprised of a diverse and global group of public and private pension funds, consultants, endowments, foundations, funds of funds, and family offices.
“I think that there is widespread agreement this time that we need economic growth rather than fiscal tightening to exit the crisis and sustain the enormous public debts," said FedericoSanti, analyst at risk consulting firm EurasiaGroup. Italy is to be the largest recipient of the EU funds with around €190 billion, of which €70 billion are grants.

They urged the government to consult with labor unions in establishing a system similar to the sovereign wealth fund — a state-owned fund supported by revenue from commodity exports, foreign-exchange reserves and other investments — to make sure that the pension scheme does not collapse.
LaBrant has argued the donors of Michigan Citizens for Fiscal Responsibility, a nonprofit group that provided about $1.9 million in funding for Unlock Michigan through a series of contributions, should have to file its own fundraising disclosures under state law.
A recent estimate from the Boston Consulting Group concluded states closed as much as 60 percent of the K-12 “device divide” by December, and up to 40 percent of the “connectivity divide,” with help from federal funding and the private sector. Yet the consulting group estimated up to 12 million K–12 students were still “under-connected” in the U.S.
