Fe3N2, also known as Iron (II) nitride, is an ionic compound.
Ionic compounds are compounds that consists of metals and non-metals bonded with ionic bonds. The metal ion gives up electron(s) to the non-metals.
Since iron is a metal and nitrogen is an non-metal, the bond they would form would be an ionic bond. Iron gives up 2 electrons to form iron(II) ion, while nitrogen gains 3 electrons to form nitride ion. Since one iron cannot let a nitrogen gain 3 electrons, so in the compound, there would be 3 iron (ii) ions that has given up 6 electrons in total while 2 nitride ions have gained 6 electrons in total.
Atomic weight is Ar of the atom (what you see on the periodic table)
atomic weight<span> is relative </span>atomic mass, so yeah same thing
Answer:
- Acetic acid (CH₃COOH) and hydronium ion (H₃O⁺)
Explanation:
Hello,
In this case, based on the acid-base theory which states that acids are known as H⁺ donors, if we consider the direct reaction:

It is clear that the acetic acid is the first H⁺ donor as it losses one H⁺ to turn into the acetate ion. Moreover, if we consider the inverse reaction:

It is also clear that the hydronium ion is the second H⁺ donor as it losses one H⁺ to turn into water.
Best regards.
The three subatomic particles are proton, neutron and electron. Proton and neutron are present inside the nucleus where as the electrons are present revolving in the orbits around the nucleus. Isotopes of the same element have same atomic number but different number of neutrons. Similarly, ions of an element have different number of electrons. For example, neutral Ag atom has 47 electrons, where as
ion has 46 electrons. Atomic number which is the number of protons is unique for an element. So the number of protons would remain same for different atoms of same element Ag.
