(a)
Interpretation:The given structure needs to be identified as an atomic element, molecular element, and compound.
Concept introduction:Compound is defined as a substance that consists of two or more different elements that chemically combine in a fixed ratio by mass. A compound has new properties compared to its constituent elements.
(a)
Answer to Problem 3A
It is a compound.
Explanation of Solution
The given structure is made up of three atoms of two different elements. Hence, it is a compound. Examples of this type of molecules are

The given structure is made up of three atoms of two different elements. Hence, it is a compound. Examples of this type of molecules are
(c)
Interpretation: The given structure needs to be identified as an atomic element, molecular element, and compound.
Concept introduction: A molecular element is a substance in which two or more atoms are bound together. Generally, they are diatomic nonmetals that exist as a molecule.
(c)
Answer to Problem 3A
It is a molecular element.
Explanation of Solution
The given structure is diatomic with the same atom bonded to each other. Hence, they are molecular elements (non-metals such as oxygen, nitrogen and fluorine are examples of this type).
(d)
Interpretation: The given structure needs to be identified as an atomic element, molecular element, and compound.
Concept introduction: An atomic element is present independently in the form of atoms and it can react with other elements to forma compound. They are monoatomic in nature.
(d)
Answer to Problem 3A
It is an atomic element.
Explanation of Solution
The given structure is monoatomic and Hence, it is an atomic element (metals such as copper, silver and gold are examples of this type).

(3) points) OH OH بر بد بدید 2 3arrow_forwardThere is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
