An element is a pure substance that cannot be broken down by chemicals. It made completely of one type of atom. Copper is one such element of the periodic table. It is represented by the symbol Cu and has
Answer to Problem 9STP
Explanation of Solution
Given information:
Physical properties of three elements:
Element | Symbol | Melting Point
|
Color | Density
|
Sodium | Na | 897.4 | Grey | 0.986 |
Phosphorous | P | 44.2 | White | 1.83 |
Copper | Cu | 1085 | Orange | 8.92 |
Quantitative data has numbers. It is represented in the form of counts or numbers where there is a unique numerical value associated with each data set.
In the given table, melting point and density are the quantitative data for every element whereas symbol and color are the qualitative data.
Therefore,
Hence, copper’s
