Which correctly summarizes the trend in electron affinity? it tends to be very high for group 2
it tends to be more negative across a period
it tends to remain the same across periods
it tends to be more negative down a group
Answers
The answer is it tends to be more negative down a group. This is because as you go down the periodic table, the elements have more electron shells in their atoms. This makes the outermost shells less attracted to the nucleus due to their greater distances from the nucleus. Therefore, these shells are less likely to attract electrons (hence lower electron affinity) and are even more likely to lose electrons from their outer electron orbits.
Answer:
it tends to be more negative across a period
Explanation:
We have to remember that the periodic table is arranged accordingly to the number of electrons that the elements have in their outer valance shell, so the closer you are to the right of the periodic table the closer you get to the elements taht have the most electrons in their outer valance shells, this means that they have a greater negative electron affinity, which means that the elements on the right are more willing to gain an electron.

T₁ ( K ) = 98.15ºC + 273 = 371.15 K
V₂ = ?
T₂ ( K) = -18.50ºC + 273 = 254.5 K
V₁ / T₁ = V₂ / T₂
42.3 / 371.15 = V₂ / 254.5
371.15 x V₂ = 42.3 x 254.5
371.15 x V₂ = 10765.35
V₂ = 10765.35 / 371.15
V₂ = 29.00 mL

The distance (in meters south) the plate will be given that the plate is moving at a rate of 2 cm/year is 80 meters south (last option)
How do i determine the distance?
Speed is defined as distance travelled per unit time. This is mathematically written as
Speed = Distance travelled / time
If we make distance the subject, we have
Distance travelled = Speed × time
The following data were obtained from the question:
- Speed of plate = 2 cm/year = 2 / 100 = 0.02 m/year
- Time = 4000 years
- Distance travelled =?
Distance travelled = Speed × time
Distance travelled = 0.02 × 4000
Distance travelled = 80 meters south
Thus, we can conclude that the distance travelled is 80 meters south (last option)

the plate will be 80 meters south from its original location in 4,000 years. The correct answer is (d) 80 meters south.
The plate moves south at a rate of 2 cm/year. To find out how many meters south it will be in 4,000 years, we need to convert the years to centimeters and then meters.
In 4,000 years, the plate will have moved: 2 cm/year x 4,000 years = 8,000 cm.
Now, to convert 8,000 cm to meters, we need to divide by 100 (since there are 100 centimeters in a meter):
8,000 cm / 100 = 80 meters.
So, the plate will be 80 meters south from its original location in 4,000 years. The correct answer is (d) 80 meters south.
