❓ Frequently Asked Questions
What is an element?
An element is a pure substance made of only one type of atom and cannot be broken into simpler substances by chemical means. Each element is defined by its number of protons (atomic number).
How is the periodic table organized?
Elements are arranged in order of increasing atomic number. Columns (groups) have similar properties; rows (periods) indicate energy levels. The table is also divided into s, p, d, and f blocks.
What is the difference between atomic number and atomic mass?
Atomic number (Z) is the number of protons and identifies the element. Atomic mass is the total number of protons and neutrons in the nucleus.
Which common elements are essential in everyday life?
Hydrogen, Carbon, Nitrogen, Oxygen, Calcium, and Iron are among the essentials; they form water and organic molecules, proteins, bones, blood, and many materials.
