CaF2 is an ionic compound, since its the only substance in ur group that is formed with a non-melta and a metal NH3 <span>is not an example of a molecular formula.</span>
Answer:
is the isotopic notation of the atom
Explanation:
The isotope notation is:
<em>Where a is the mass number = Number of protons + Number of neutrons</em>
<em>b is atomic number = Number of protons</em>
The atomic number define the nature of the atom, the element with atomic number = 15 is phosphorus, P:
a = 15 protons + 16 neutrons = 31
b = 15
is the isotopic notation of the atom.
Answer:
The ability to decompose
Explanation:
A property is a chemical property when it changes the chemical structure of a substance after a reaction.
Density and color are both physical properties.
Even though melting point may seem like a chemical property, when something melts, only the physical state changes, and the chemical structure does not change, and therefore, is a physical property.
The ability to decompose is a chemical property. When something decomposes, the chemical structure of many molecules change, and therefore, is classified as a chemical property.
