Answer:
the number of electrons in it's outermost energy level
Explanation:
if the number of electrons in its outermost energy level is less than 4 that's the ion reacts by losing electrons and is thus the ion is positively charged
is the number of electrons in the outermost energy level is more than 48 react by gaining electrons and thus it is negatively charged

Since it is easily calculated using a calculator, I assume you need this done in the head.
Yes, you can do that.
It takes a few words to explain this, but if you understand how this is done, it goes fast.
27=3*9
so 7263*27 = (7263 * 3) * 9
so first multiply 7263 by 3.
72*3=216, 63*3=189
so 3*7263=21789
So far so good.
Now you can multiply anything by nine by subtracting from the right neighbour, starting from the right.
For example, 27*9. the right neighbour of 7 is 0, borrow 1, so 10-7=3
the right neighbour of 2 is 7, but we borrowed 1, so 6. 6-2=4
At the beginning of the number 27, we add a zero which we subtract from the right neighbour 2 to get 2.
So 27*9=243.
Now for 21789, we have successively
(10)-9=1
8-8=0 (9 was borrowed to become 8)
8-7=1
7-1=6
(11)-2=9
and finally
1 -0 = 1 (2 was borrowed to become 1)
So the final answer is 196101

the anwser is <u>A. Substitution </u>
Explanation:
hope this helps :) the heres the explanation
