what elements are designated by each symbol or group of symbols? a) CU and Cu, b) Os and OS, c) Ni and NI, d) BIN, BiN, and BIn

a) CU: corresponds to carbon and uranium. Cu: corresponds to copper.

b) Os: corresponds to osmium. OS: Corresponds to oxygen and sulfur.

c) Ni: corresponds to nickel. NI: corresponds to nickel and iodine.

d) BIN: corresponds to boron, iodine and nitrogen. BiN: corresponds to bismuth and nitrogen. BIn: corresponds to boron and indium.

Explanation:

Hello.

Here, for establishing the elements in each numeral, we must remember that elements could have one capital letter only or one capital letter and one lower case only, say, nitrogen (N) or selenium (Se). In such a way, we have:

a) CU: corresponds to carbon and uranium. Cu: corresponds to copper.

b) Os: corresponds to osmium. OS: Corresponds to oxygen and sulfur.

c) Ni: corresponds to nickel. NI: corresponds to nickel and iodine.

d) BIN: corresponds to boron, iodine and nitrogen. BiN: corresponds to bismuth and nitrogen. BIn: corresponds to boron and indium.

Best regards.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
