Question

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:

Step1: Determine element and compound

Elements are pure substances with one - type of atom and are listed on the periodic table. Compounds are made of two or more different elements chemically combined. Aluminum (Al) is an element as its name is on the periodic chart. Sodium chloride (NaCl) is a compound as it is made of sodium (Na) and chlorine (Cl) elements chemically bonded.

Step2: Find 5 recognizable elements

Using the periodic table, common elements can be identified.
Element 1 - Hydrogen, H
Element 2 - Oxygen, O
Element 3 - Carbon, C
Element 4 - Iron, Fe
Element 5 - Copper, Cu

Answer:

Aluminum (Al) is the element. Sodium chloride (NaCl) is the compound. Reason: Elements are on the periodic table, compounds are made of multiple elements.
Element 1 - Hydrogen, H
Element 2 - Oxygen, O
Element 3 - Carbon, C
Element 4 - Iron, Fe
Element 5 - Copper, Cu
