Which ion is the largest out of oxide (O-2), sulfide (S2-), and telluride (Te-2)?

Lithium (Li) has the lowest ionization energy out of lithium (Li), nitrogen (N), and neon (Ne).

Electron Configuration and Atomic Structure

The nitrogen atom has three electrons in its 2p subshell, indicating its placement in the periodic table.
Bromine's correct electron configuration is [Ar]4s²4p⁶4d⁹, showcasing its complex arrangement of electrons.

Key Concepts in Chemistry

Ionization energy refers to the energy necessary to remove an electron from an isolated atom, impacting how elements react chemically.
Electronegativity describes the ability of an atom in a molecule to attract shared electrons, affecting bond formation and molecular polarity.

Atomic and Ionic Comparisons

Simple cations are generally smaller than their respective neutral atoms, due to the loss of electrons leading to reduced electron-electron repulsion.
Among the elements studied, fluorine exhibits the smallest atomic radius when compared to carbon and magnesium.

Element Characteristics

Oxygen is noted for having the highest electronegativity in comparison with aluminum and carbon, which influences its reactivity and bonding.
Strontium is identified as the most metallic element compared to beryllium and calcium, indicating a tendency to lose electrons easily.

Ionic Size

Tellurium ion (Te²⁻) is the largest in size among the ions of oxygen (O²⁻), sulfur (S²⁻), and itself, highlighting the impact of added electrons on ionic radius.

Ionization Energy Trends

Lithium has the lowest ionization energy compared to nitrogen and neon, making it more reactive and easier to ionize.
