The correct student is Student D, who says that Fluorine (F) has the highest ionization energy because the smaller the atom, the stronger the attraction between protons and valence electrons.
The stronger the attraction, the more energy is needed to remove a valence electron.
Ionization energy refers to the energy required to remove an electron from an atom. Smaller atoms have a stronger attraction between the positively charged protons in the nucleus and the negatively charged electrons in the outermost energy level. As a result, it takes more energy to remove an electron from a smaller atom like fluorine. This is because the electrons are held more tightly due to the stronger attraction.
So, the reasoning provided by Student D correctly explains why Fluorine has the highest ionization energy among Selenium (Se) and Fluorine (F).

I think the Answer is C because Flourine is stronger in electron attraction and is smaller so it has a stronger electronic pull. Hope this helps :)
The element with the electron configuration 1s² 2s² 2p⁶ 3s² 3p² is silicon (Si).
In the electron configuration notation, each number and letter represents a specific energy level (or shell) and subshell that contains electrons in an atom. The numbers indicate the energy levels (principal quantum numbers), and the letters represent the type of subshell (s, p, d, or f).
Let's break down the electron configuration for silicon (Si):
1s²: This indicates that the first energy level (n = 1) has two electrons in the s subshell.
2s²: This indicates that the second energy level (n = 2) has two electrons in the s subshell.
2p⁶: This indicates that the second energy level (n = 2) has six electrons in the p subshell.
3s²: This indicates that the third energy level (n = 3) has two electrons in the s subshell.
3p²: This indicates that the third energy level (n = 3) has two electrons in the p subshell.
To find the element with this electron configuration, we count the total number of electrons: 2 + 2 + 6 + 2 + 2 = 14 electrons. Since silicon (Si) has 14 electrons, it matches the given electron configuration.
Silicon is a chemical element in the periodic table with atomic number 14. It is a metalloid, meaning it has properties of both metals and nonmetals. Silicon is widely used in various industries, including electronics, as it is a key component of semiconductors and is crucial for modern technology.
