Li is a larger atom than Ne, even though Ne has 7 more protons and 7 more electrons than lithium. All of the statements below are true. Which statement is the reason why Ne is smaller than Li? A) Li is a metal and neon is a nonmetal. The effective nuclear charge is larger for neon compared to lithium. The larger effective B) nuclear charge in neon pulls all of the orbitals down to smaller sizes. C) Neon has more electrons than lithium so the screening is larger in neon. D) Neon has a filled n=2 shell whereas lithium only has one electron in a 2s subshell.
Electron Affinity
When an element undergoes a chemical reaction, it either gains energy or loses energy. This gain or loss of energy is due to the phenomena that occur at atomic level. During reaction, atoms either gain electrons from other atoms or lose electrons to other atoms, and in that process, energy is produced.
P-Block Elements
Elements which are present on the right side of the periodic table are called p-block elements. In addition to the noble gases, they include the families of boron, mercury, nitrogen, oxygen and fluorine. These elements have diverse real-life implementations that we regularly experience around us.
Metals and Non-metals
The periodic table is composed of metals, semi-metals and nonmetal elements. The physical and chemical properties of metals and nonmetals differ from each other. The study of metals and nonmetals will help one to understand the appropriate application of the particular element.
