Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula SnCl2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot. SnCl2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating. Tin(II) chloride should not be confused with the other chloride of tin; tin(IV) chloride or stannic chloride (SnCl4).
Following the completion of the conquest of Canaan by the Israelite tribes after about 1200 BCE, Joshua allocated the land among the twelve tribes. However, in the case of the Tribes of Gad, Reuben and half of Manasseh, Moses allocated land to them on the eastern side of the Jordan River and the Dead Sea. (Joshua 13:24-28) The Tribe of Gad was allocated the central region of the three, east of Ephraim and West Manasseh, though the exact location is ambiguous.
"The border was Jazer, and all the cities of Gilead, and half the land of the children of Ammon, unto Aroer that is before Rabbah; and from Heshbon unto Ramath-mizpeh, and Betonim; and from Mahanaim unto the border of Lidbir and in the valley, Beth-haram, and Beth-nimrah, and Succoth, and Zaphon, the rest of the kingdom of Sihon king of Heshbon, the Jordan being the border thereof, unto the uttermost part of the sea of Chinnereth beyond the Jordan eastward."Among the cities mentioned in Numbers 32:34 as having at some point been part of territory of the Tribe of Gad were Ramoth, Jaezer, Aroer, and Dibon, though some of these are marked in Joshua 13:15-16 as belonging to Reuben.
According to the Torah, the tribe consisted of descendants of Gad the seventh son of Jacob, from whom it took its name. However, some Biblical scholars view this also as a postdiction, an eponymous metaphor providing an aetiology of the connectedness of the tribe to others in the Israelite confederation. In the Biblical account, Gad is one of the two descendants of Zilpah, a handmaid of Jacob, the other descendant being Asher; scholars see this as indicating that the authors saw Gad and Asher as being not of entirely Israelite origin (hence descendants of handmaids rather than of full wives). In common with Asher is the possibility that the tribal name derives from a deity worshipped by the tribe, Gad being thought by scholars to be likely to have taken its name from Gad, the semitic god of fortune;Like Asher, Gad's geographic details are diverse and divergent, with cities sometimes indicated as being part of Gad, and sometimes as part of other tribes, and with inconsistent boundaries, with Gilead sometimes including Gad and sometimes not. Furthermore, the Moabite Stone seemingly differentiates between the kingdom of Israel and the tribe of Gad, presenting Gad as predating Israel in the lands east of the Jordan,. These details seems to indicate that Gad was originally a northwards-migrating nomadic tribe, at a time when the other tribes were quite settled in Canaan.In the biblical account, Gad's presence on the east of the Jordan is explained as a matter of the tribe desiring the land as soon as they saw it, before they had even crossed the Jordan under Joshua, and conquered Canaan. Classical rabbinical literature regards this selection of the other side by Gad as something for which they should be blamed, remarking that, as mentioned in Ecclesiastes, the full stomach of the rich denies them sleep. When they arrived at the Jordan and saw the fertility of the land, they said: "One handful of enjoyment on this side is better than two on the other" (Lev. R. iii. 1). However, because they crossed the river to help their brethren in the conquest of Palestine, just as Simeon did when he took his sword and warred against the men of Shechem, they were found worthy to follow the tribe of Simeon at the sacrifices on the occasion of the dedication of the Tabernacle (Num. R. xiii. 19). Moses was buried in the territory of Gad (Soṭah 13b; Yalḳuṭ, Wezot ha-Berakah, p. 961). According to some, Elijah was a descendant of Gad (Gen. R. lxxi.). The tribes of Gad and Reuben were the first that went into exile (Lam. R. i. 5).
The location was never secure from invasion and attacks, since to the south it was exposed to the Moabites, and like the other tribes east of the Jordan was exposed on the north and east to Aram-Damascus and later the Assyrians.
From after the conquest of the land by Joshua until the formation of the first Kingdom of Israel in c. 1050 BC, the Tribe of Gad was a part of a loose confederation of Israelite tribes. No central government existed, and in times of crisis the people were led by ad hoc leaders known as Judges (see the Book of Judges). With the growth of the threat from Philistine incursions, the Israelite tribes decided to form a strong centralised monarchy to meet the challenge, and the Tribe of Gad joined the new kingdom with Saul as the first king. After the death of Saul, all the tribes other than Judah remained loyal to the House of Saul, but after the death of Saul's son Ish-bosheth, successor to the throne of Israel, the Tribe of Gad joined the other northern Israelite tribes in making Judah's king David the king of a re-united Kingdom of Israel. However, on the accession of David's grandson Rehoboam, in c. 930 BC the northern tribes split from the House of David and from Saul's tribe Benjamin to reform Israel as the Northern Kingdom. Gad was a member of the Northern Kingdom until the kingdom was conquered by Assyria in c. 723 BC and the population deported.

According to the Hebrew Bible, the Tribe of Gad (Hebrew: גָּד, Modern: Gad, Tiberian: Gāḏ, "soldier" or "luck") was one of the Twelve Tribes of Israel who, after the Exodus from Egypt, settled on the eastern side of the Jordan River. It is one of the ten lost tribes.
Though initially forming part of the Kingdom of Israel, from the biblical account it appears that under Uzziah and Jotham the tribe of Gad joined with the kingdom of Judah instead. Nevertheless, when Tiglath-Pileser III annexed the kingdom of Israel in about 733-731 BC, Gad also fell victim to the actions of the Assyrians, and the tribe were exiled; in the Talmud, it is Gad, along with the tribe of Reuben, that are portrayed as being the first victims of this fate. The manner of the exile led to the further history of the tribe being lost, and according to the Book of Jeremiah, their former lands were (re)conquered by the Ammonites. Simcha Jacobovici the Naked Archeologist claims to have found part of the descendants of the Tribe of Gad in southern Spain in Andalucia in a region called Cadiz.
