Fluorine it has a atomic radius of 42
Answer:
B) 1:100
Explanation:
this explanation is actually simple.
you can see this problem as a simple comparation if you move for example
1:10
if you move 1 cm you are going to move 10cm in the other side usually is used for planes in architecture or sizing issues, so, if the scale need to be grater, that is if is necessary to increase the number inthe right side in this case 10 cm to 100cm it is because in 100 the resolution is better.
you can see this problem as a fraction
1/10 or 1/1000
Answer:
There are 5 valence electrons
Explanation:
Valence electrons are electrons found in the outermost shell of an atom.
Answer:
64°
Explanation:
The triangle is an isosceles triangles (both legs are equal to the radius of the circle), so that means the base angles are the same.
Angles of a triangle add up to 180°, so:
128 + 2x = 180
2x = 52
x = 26
∠1 is complementary to the base angle, so:
∠1 = 90 − 26
∠1 = 64
