5 0

Answer:

yes it is ( From +3 to 0 )

Explanation:

If this is the balanced equation:

AlCl3     +    3Na ——>    3NaCl      +      Al

Al      Cl        3Na             Na     Cl            Al

+3     -3        0                    +1       -1            0

ddd [48]

Answer:

2/3

Explanation:

Crystals structures can also be seen when two elements combines together and the perfect example is Al₂O₃ which is given in the question above. Just like it is given in the question above, the kind of arrangement in the crystal structure for Al₂O₃ is called HCP which stands for Hexagonally Closed Pack.

The aluminum ions which is in form of Al³⁺ occupies the two-third[2/3] positions while the position that the oxygen ion occupies is one[1].

The elements silicon (atomic number 14) and chlorine (atomic number 17) are both in Period 3. Which is the more reactive element
Svetlanka [38]

Answer;

-Chlorine is more reactive than silicon

Explanation;

-As you move across a period, the nuclear charge will increase; the number of energy levels will stay the same, so there is a stronger and stronger attraction for the electrons.

-The electrons are being held more tightly as you move across a period. It becomes more and more difficult to lose electrons and consequently the reactivity of non metals increases as you go from left to right across the periodic table; Therefore; chlorine is more reactive than silicon.
