Web1st I.E.: In group 1 and 7 the 1st I.E. is the same. Its harder in Li to remove the electron then is in Cs because the last electron is closer to the Nucleus but in Cs its easier because the valance electron in Cs is much further … WebHow relative atomic mass increase down group 7 and why. Reactivity decreases down the group. This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding increases, meaning that the electron is less attracted to the nucleus.
As you move down group 1 and 7 elements get more …
WebAs you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again the elements get more reactive. Is as follows: To remember how the … WebSep 14, 2024 · Neutral atoms tend to increase in size down a group and decrease across a period. When a neutral atom gains or loses an electron, creating an anion or cation, the atom's radius increases or decreases, respectively. This module explains how this occurs and how this trend differs from that of atomic radii. Shielding and Penetration sly dog head
Why does the group 7 element become more darker as we move down the group?
WebFeb 12, 2024 · That group is the halogens: F, Cl, Br, I, At, and Ts (Ts is one of the last elements discovered). Those elements have 7 valence electrons (notice that it is the … WebThe answer is twofold: either it depends on the number of protons in the nucleus (the more protons in the nucleus, the harder it will be to lose an electron because the … WebWhy does ionization energy decrease moving down a group in the periodic table? because the atoms get closer to noble gas configuration because shielding decreases because nuclear charge decreases because effective nuclear charge increases because the outer electrons get further from the nucleus about us carcard privacy policy terms of use … solar records label
