Calcium is a solid at room temperature.
At standard conditions, which are typically defined as 20-25 degrees Celsius (68-77 degrees Fahrenheit) and a pressure of 1 atmosphere, calcium exists in a solid state. This is because calcium has a melting point of about 842 degrees Fahrenheit (450 degrees Celsius), which means it remains solid well within the temperature range of typical room conditions. Additionally, as an alkaline earth metal, calcium exhibits the properties of a metal, including malleability and ductility, reinforcing its classification as a solid at these temperatures.
