Problem 16a,b,c,d,e

Chapter 1, Problem 16a,b,c,d,e

Give the chemical symbol or name for each of the following elements, as appropriate: (a) rhenium (b) tungsten (c) cesium (d) hydrogen (e) indium

Verified step by step guidance

Identify the element in question from the periodic table.

Locate the element 'rhenium' in the periodic table to find its chemical symbol.

Note that the chemical symbol for an element is typically one or two letters, the first letter always being capitalized and the second letter, if present, being lowercase.

Check the atomic number of rhenium to ensure the correct element is identified.

Provide the chemical symbol for rhenium based on its position in the periodic table.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Chemical Symbols

Chemical symbols are one- or two-letter abbreviations used to represent chemical elements. Each symbol is unique to an element and is derived from its English or Latin name. For example, the symbol for rhenium is 'Re', which helps in identifying the element in chemical equations and periodic tables.

Element Names

Element names are the official names given to chemical elements, often reflecting their properties, discoverers, or places of discovery. Rhenium, for instance, is named after the Rhine River in Europe. Understanding element names is crucial for recognizing and communicating about different substances in chemistry.

Periodic Table

The periodic table is a systematic arrangement of elements based on their atomic number, electron configuration, and recurring chemical properties. It provides essential information about each element, including its symbol, atomic mass, and group classification. Familiarity with the periodic table is vital for identifying elements like rhenium and understanding their relationships with other elements.

Textbook Question

A solid white substance A is heated strongly in the absence of air. It decomposes to form a new white substance B and a gas C. The gas has exactly the same properties as the product obtained when carbon is burned in an excess of oxygen. Based on these observations, can we determine whether solids A and B and gas C are elements or compounds?
