Answer:
natural flame,oxidising flame
The nucleus consists of protons and neutrons. Since neutrons are neutral, they are not taken account of in the net charge. The number of protons = the net charge of the nucleus and that is shown by the atomic number. For example, the atomic number of Oxygen is 8 which means that it has 8 protons; a net charge of +8 only in the nucleus. On a deeper note, a neutral atom has the same amount of protons as electrons, so theoretically, oxygen is supposed to have 8 valence electrons, but sometimes it has a deficiency of 2 electrons (making an oxygen ion), so the net charge would be -2 of the <em>whole</em> atom (since it's supposed to be neutral), but the net charge of the<em> nucleus</em> itself would still be +8.
Answer:
The answer to your question is: Iron oxidizes and Copper reduces
Explanation:
An element oxidizes when it loses electrons
An element reduces when it gains electrons
Then
Fe ⇒ Fe⁺² Now, is more positive, it loses electrons
Cu⁺² ⇒ Cu Now, is more negative, it gains electrons
Iron oxidizes and Copper reduces
Answer:
III, IV, and V
Explanation:
The complex [CO(NH3)6]3+ is a diamagnetic complex. It a low spin d^6 complex. Most d^6 complexes are low spin due to the higher crystal field stabilization energy of the low spin over the high spin arrangement.
d^6 metal complexes are known to be octahedral (a coordination number of 6 leads to octahedral geometry). Octahedral complexes does not have geometric isomers rather, may exist as the fac or her stereo isomers.
