StopLearn Team Staff answered 11 months ago The first twenty elements in the periodic table exist in different states of matter at room temperature (25°C or 298 K). Here is a breakdown of the states of matter for each of these elements:
- Hydrogen (H): Gas
- Helium (He): Gas
- Lithium (Li): Solid
- Beryllium (Be): Solid
- Boron (B): Solid
- Carbon (C): Solid
- Nitrogen (N): Gas
- Oxygen (O): Gas
- Fluorine (F): Gas
- Neon (Ne): Gas
- Sodium (Na): Solid
- Magnesium (Mg): Solid
- Aluminum (Al): Solid
- Silicon (Si): Solid
- Phosphorus (P): Solid
- Sulfur (S): Solid
- Chlorine (Cl): Gas
- Argon (Ar): Gas
- Potassium (K): Solid
- Calcium (Ca): Solid
As shown above, the first twenty elements include gases (Hydrogen, Helium, Nitrogen, Oxygen, Fluorine, Neon, Chlorine, Argon), solids (Lithium, Beryllium, Boron, Carbon, Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulfur, Potassium, Calcium), and one liquid (Mercury is not included in the first twenty elements).
It’s important to note that the state of an element can change with temperature and pressure. The states listed here are specifically for room temperature conditions.
