Numbers (of objects) that can be arranged into a square array are called square numbers. Not a square number: Square arrays must be full if we are to count the number as a square number. Here are 12 pennies arranged in a square, but not a full square array. The number 12 is not a square number.
Informally: When you multiply a whole number times itself, the resulting product is called a square number, or a perfect square or simply a square. So 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.
