Answer:
Left to right and top to bottom
Explanation:
On the periodic table, the properties repeat from left to right and from top to bottom.
Periodic properties have a pattern from the top to the bottom or down a group or family.
Also, across the period from left to right, they also show a repeating pattern.
- Certain properties increase from left to right and decreases from top to bottom. E.g. electronegativity.
- Also, some properties decreases from left to right and increases from top to bottom e.g. atomic radius.
Answer:
Explanation:
The dot product of two vectors 
and 
is given by
The dot product of two orthogonal vector is always zero thus if 
and 
, their dot product would be
The photosphere<span> is the visible "surface" of the Sun (left</span>
I = Current q = total charge t =time taken to pass electron from a certain point. Number of Electrons =2.5×1019. Total charge q=ne=2.5×1019×1.6×10−19=2.5×1.6= 4C.
D.
Most are poor conductors of electricity.
