I think B is the best answer although it isn't complete. The atoms ARE getting larger, the outer electrons ARE farther away AND there are more shielding electrons between the nucleus and the outer electron so it is easier to remove the outer electron.
What is one way in which Noble Gases are different from other elements? a. Noble Gases have low boiling points b. Noble gases have high melting points c. Noble gases have extremely high densities d. Noble gases have unusually high
All the noble gases except helium crystallize with fcc structures. Derive an equation relating the atomic radius to the density of an fcc solid of given molecular weight and apply it to deduce the atomic radii of the noble gases.
Which trends are observed when the elements in Period 3 on the Periodic Table are considered in order of increasing atomic number? (1) The atomic radius decreases, and the first ionization energy generally increases. (2) The
Shown below are several options for the box notations of the ground state electron configuration of the following gas-phase species. Identify the correct electronic configuration. i. Al2− ii. Mn (a)Select the reason that
For the elements in row 2 of the PT discover the relationship between ionization and the family number of the element Element. Family. Ionization Ener Lithium. 1 13.6 beryllium. 2. 9.3 boron. 13. 8.3 carbon. 1 4. 11.27 nitrogen.
Which of the statements correctly describes the reactivity of noble gases, according to the octet rule? They have eight electrons in their valence shell, so noble gases are very unreactive. They have eight electrons in their
The ionization energies of Li, Na, K, Rb, and Cs are respectively 5.4, 5.1, 4.3, 4.2, and 3.9 eV. All are in Group 1 of the periodic table. Explain the decrease in ionization energy with increasing atomic number in this group.
1) How does the atomic radius change from left to right across a period in the periodic table? A) It tends to decrease*** B)It tends to increase C) It first increases, then decreases D) It first decreases, then increases 2) What
