Answer:
<h3>the true statement is an atom contains the same number of electron and proton</h3>
Explanation:
let us see the behaviour of the sub atomic particles
- nutrons and protons found in the nucleus of an atom
- an atom have the same number of electron and proton but they have different charge
- nutron is chargeless particle
- most mass of the atom concentrated in the nucleus of an atom
- electrons have almost 0 mass from an atom
- mass of proton and mass of nutron are equvalent or almost equal
there are many properties of subatomic particles i have listed some of them above .
<h3>I think it is help ful for you </h3>
It’s a base because it has hydroxide (oh) and not just hydrogen.
The answer to this question is going to be letter A
Since it is an ionic compound. it would be a good electrical conductor
Answer is: formula of the complex is [Cr(NH₃)₂(SCN)₄<span>]</span>⁻<span>.
This complex has negative charge (-1) because chromium (central atom or metal) has oxidation number +3, first ligand ammonia has neutral charge and second ligand thiocyanate has negative oxidation number -1:
+3 + 2</span>·0 + 4·(-1) = -1.
