Potassium nitrate is solid state of matter. and look like as shown in the figure. I've added a diagram for your easiness
Copper: 2+Oxygen: 2-Nitrogen: 5+
The element nickel is a solid at room temperature.
No. It is an ion with two different elements: nitrogen and oxygen.
It is normally solid. It melts at 221oC.
It could be either. For example, a molecule of O2 or Cl2 is an element, but one of CH4 or NO3 is a compound.
It is in a solid state of matter.
No. It is an element. It is in a state of matter, specifically "Solid".
matter can be softed by its state in rtp. another way of sorting is element by element.
Copper: 2+Oxygen: 2-Nitrogen: 5+
a natural state of matter would be tellurium
Gas
Liquid
Which element changes the density of matter
The element nickel is a solid at room temperature.
the state of matter at room temperature for the element Europium is a liquid.
chlorine is a gas
Its presumably solid...
