Answer:
Ne with eight dots
Explanation:
On the periodic table, Neon is in group 8A. The group can be used to determine the number of valence electrons.
The dots in the Lewis structure diagram represent the number of valence electrons.
Answer:
The absolute uncertainty is 10%.
Explanation:
The absolute uncertainty, sometimes referred to as absolute error, is the size of the possible range of values where by the actual or true value of a measurement probably lies.
The uncertainty of the 50 mL beaker is given as ± 10%. This implies that the volume recorded using the beaker will either be 10 % above or below the actual volume.
The absolute uncertainty ignores the direction of the error, whether above or below, and is mostly concerned with the magnitude of the error. We simply ignore the signs of the uncertainty and this will give the value of the absolute uncertainty.
I think its D(a battery,a length of wire and so on...)
