During a reaction, a halogen chemically combines with a Group 1 element to form a compound. how does this reaction occur, based
on the atomic structure of each element? A) a halogen atom loses an electron to an atom of Group 1 element
B) a halogen atom gains an election from an atom of a Group 1 element
C) a halogen atom loses two electrons to an atom of a group 1 element
D) a halogen atom shares an electron with an atom of a Group 1 element
The answer for this question would be B. Both elements, one being a Group 1 and the other being a Group 17, want to attain the octet of electrons in the outermost shell for chemical stability. The Group 1 element has one too many electrons, and the 17 is lacking one. To increase the stability of the system, the Group 1 can donate the extra electron to the Group 17 so that both can emulate a stable octet. In doing so, two ions are produced (elements that have a net charge that isn’t 0), and thus we have an “ionic bond.”
Zinc nitrate gives white ppt. which dissolves in excess ammonium hydroxide and produce a colorless solution whereas lead nitrate gives a chalky white ppt. of lead hydroxide which doesnot dissolve.
My guess would be "B) they were produced by volcanoes" because hawaii has a bunch of volcanoes and volcanoes can produce extra land. While the other answers wouldn't make sense. Definitely B.
A drainage basin is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water
