what is nickel's state of matter at room temperature

Assistance needed.

Wouldn't it be a solid? (according to wikipedia's page on nickel) ......

To determine the state of matter of an element at room temperature, we can refer to the periodic table or use our knowledge of the element's physical properties.

Nickel (Ni) is an element located in the d-block of the periodic table with atomic number 28. At room temperature, which is typically around 20 to 25 degrees Celsius or 68 to 77 degrees Fahrenheit, nickel is in a solid state of matter.

Solid is one of the three main states of matter, along with liquid and gas. In the solid state, particles of a substance are tightly packed together in a fixed arrangement, and they vibrate but do not move around as freely as in a liquid or gas.

So, the answer to your question is that nickel is in a solid state of matter at room temperature.
