<span>Ionic compounds are chemical compounds in which ions are held together in a lattice structure by ionic bonds. They have a high melting and boiling point, and they have a high hardness and are very brittle. The cations and anions are stuck together in a sense. So in this case, sodium (Na) is attracted to Chlorine (Cl).</span>
4.33898305 is the density
Divide mass/volume
Answer:
This is isotope of barium
Explanation:
It has atomic number of 56, mass number is 130 (56 + protons + 76 neutrons) oxidation number is +2 it has two more protons than electrons ( 56 - 54 = 2 )
Explanation:
Characteristic of matter that is not associated with its change in chemical composition.
CH2O2 formic acid I believe so
