Question

lab station 3. substances: elements versus compounds
in our life we work almost exclusively with compounds, but a few objects are elements, such as iron. the biggest reason for this is that elements tend to combine into compounds. if its name is on the periodic chart, it is an element. our examples: aluminum (al) versus table salt (sodium chloride: nacl)
record which is the element and which is the compound. be sure to record how you determined this.
using the periodic chart, find 5 elements you recognize. record their names and their chemical symbol (abbreviation)
element 1—
element 2—
element 3—
element 4—

Explanation:

Elements are pure substances listed on the Periodic Chart. Compounds are made of two or more different elements chemically combined. Aluminum (Al) is an element as its name is on the Periodic Chart. Table - salt (sodium chloride: NaCl) is a compound as it is made of sodium (Na) and chlorine (Cl). For the second part, common elements from the Periodic Chart can be chosen based on general knowledge.

Answer:

1. Aluminum (Al) is the element. Table - salt (sodium chloride: NaCl) is the compound. Determined by checking if the name is on the Periodic Chart (Al is, NaCl is a combination of two elements).
2. Element 1 - Oxygen, O

Element 2 - Hydrogen, H
Element 3 - Carbon, C
Element 4 - Nitrogen, N
Element 5 - Calcium, Ca
