help does anyone know this?
This is explained by the fact that at the top of the group, atoms are so the positive charge of the nucleus will be closer to any the atom may encounter as it seeks to fill its outer shell. This means the electrostatic force of between nucleus and electron will be greater. Additionally, for a smaller atom, there will be fewer inner shells of electrons to repel an incoming electron
Answers
Answers in order:
smaller
electron
attraction
Explanation:
ok so we know that a positive proton attracts the negative electron and we know that protons, neutrons are found in nucleus while the electron orbits around it.
now let's imagine an atom, could you say that with the increasing number of protons as you go down the elements of the periodic table that there is also an increasing positive charge in the nucleus?
and we know that in elements the protons and electrons are equal since they attract each other and hence the element is neutral in charge.
Now let's imagine that larger size of positive charge versus the electrons in many shells orbit.
we know that there is a specific amount of electrons per each shell, but particularly the group 17 elements, their outer shell has 17 valence electrons.
Now could we also say that having such a high number of electron in their valence shell also mean that there is a great negative charge especially in that outer shell.
so now let's imagine, both these great negative and positive charges attracting eachother, wouldn't this attraction be more stronger as compared to lower positive and negative charge? Yes
Knowing this, we can explain the reason for the actual size of the entire atom, the shells are much closer together to the nucleus due to those forces of attraction hence the atomic radii is smaller. This is also why elements with a larger number of valence electrons tend to accept electrons rather than donate.
Also know that atomic radii increase going across a period from left to right, and decrease going down a group
Answer:
Smaller for the first one
Electron for the second on
and Attract for the third one

Imagine that you are a grain of pollen on a flower that cross-pollinates
the flower of another plant of the same species. Write a journal
entry in complete sentences describing your journey. Correctly
include each of these terms in your entry: pollinator,
pollen, pistil, stamen, anther, stigma, ovary, and eggs
Answers
Answer:
As a grain of pollen on a flower, I am responsible for cross-pollinating the flower of another plant of the same species. I began my journey on the stamen of one flower, where I picked up the pollen from another. I was carried to the pistil of the next flower and deposited the pollen on the stigma. I then traveled down the style to the ovary, where I fertilized the eggs, commencing the production of the next generation of this flower.
Once I reach the stigma, I begin to germinate and grow a pollen tube that will guide me down to the ovary. Inside the ovary, I will fertilize the eggs, which will eventually develop into seeds. This process is known as cross-pollination, and it is an essential part of the plant's life cycle.
As I make my way down the pollen tube, I am filled with excitement and anticipation. I know that I am playing a critical role in the plant's reproduction, and I am proud to be a part of this process. Once I reach the ovary and fertilize the eggs, my journey will be complete, and I will have helped to ensure the continuation of the plant's species.

How does the giant squid interpret light differently than humans? Write:
A Human eye can have a visual threshold, that can only detect light around the depth of 500-600 meters, meanwhile giant squids can detect light from dark depths, and the squids eye adsorbs the blue lightHow have giant squid's eyes adapted to deep underwater? Write:
they've adapted to the deep water by having the ability to see predators, they are equipped for life in dark depths, and the large squid eyes made them able to have binocular and stereoscopic vision.Explanation:
no explanation is needed.
Answer:Hunting in the deep dark ocean isn't easy, but these cephalopods have adapted to their environment. In addition to their foot-wide eyes, which help them to absorb as much light as possible to glimpse prey, they also have long feeding tentacles.

Answers
Answer:Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
