Yes , I agree
Cations are formed by loosing one are more electrons, so the distance between nucleus and outer most electron is decreased whereas anions are formed by gaining one or more electrons ,so the distance between nucleus and outermost electron is increased.
In the given reaction Li atom loose one electron to become Li+ ,so Li+ is smallar than Li wherease F gain one electron to become F- , so F- is larger than F.
Add Answer to:

According to quantum mechanics, people should act like waves, too. The reason we do not exhibit wave properties is that our wavelengths are too small to observe. The reason the wavelengths of people are so small is that when finding the wavelength Correct answer: Planck's constant is small and people masses are much larger than that. Can anyone provide formula to prove this? Thanks!

Answer question 23-25
The unit cell for HCP is not a cube. This structure is made by placing one flat layer of a close packed hexagon arrangement of seven spheres on top of the holes in another layer, a third layer directly above first layer, and so on. This layering is referred to as A,B,A,B. Hold the model up to the light and note the tunnels that pass straight through the structure. See the figure below. 23. What is the...

Effective Nuclear Charge and Periodic Trends Coulombs Law describes the interaction between two charges and varies by the magnitude of these charges and inversely with the distance between them. ? ∝ ?1?2/? For atoms, we’ll label the charges as the nuclear charge and electron charge. ? ∝ ?????????/? As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge on the nucleus increase, so that in general. ???? = ? ∙ (+1)...

please throughly explain each step.47.21. What does it mean for two graphs to be the same? Let G and H be graphs. We say th G is isomorphic to H provided there is a bijection f VG)-V(H) such that for all a, b e V(G) we have a~b (in G) if and only if f(a)~f (b) (in H). The function f is called an isomorphism of G to H We can think of f as renaming the vertices of G...

There are many other settings in which we can ask questions related to some type of "stability" principle. Here's one, involving competition between two enterprises. Suppose we have two television networks, whom we'll call A and D. There are n prime-time programming slots, and each network has n TV shows. Each network wants to devise a schedule-an assignment of each show to a distinct slot-so as to attract as much market share as possible. Here is the way we determine...

A study that looked at beverage consumption used sample sizes that were much smaller than previous national surveys. One part of this study compared 20 children who were 7 to 10 years old with 5 who were 11 to 13. The younger children consumed an average of 8.2 oz of sweetened drinks per day while the older ones averaged 14.5 oz. The standard deviations were 10.9 oz and 8.2 oz respectively.Use younger children as population 1 (a) Do you think...
