Answer:
Na ·
Explanation:
Hello!
In this case, since the Lewis dot structure of any element illustrates the number of valence electrons at the outer shell; we can set up the electron configuration of sodium to obtain:
We can see there is only one valence electron, for that reason the Lewis dot structure is:
Na ·
Whereas the dot represents the valence electron.
Best regards!
Location = nucleus ,
and you can see the total charge on the number that written below the substance, which would be 28+

There are 1000 mg in 1 gram.
3.76/1000 = 0.00376
10^-3 = 0.001
0.001 x 3.76 = 0.00376
Answer is
3.76 x 10^-3
Answer:
47.5 mm are equal to 4.75 × 10⁻² m.
Explanation:
Meter and millimeter both are units of length. Millimeter is smaller unit while meter is larger unit. The one meter consist of thousand millimeter or we can say that one thousand millimeters are equal to one meter. In order to convert the meter value into millimeter we have to multiply the values with thousand.
we know that one meter is equal to 1000 millimeter.
1 m = 1000 mm
4.75 × 10⁻² × 1000 = 47.5 mm
47.5 mm are equal to 4.75 × 10⁻² m.
