Which of the following best helps to explain why the electron affinity of bromine has a greater magnitude than that of iodine?

Which of the following best helps to explain why the electron affinity of bromine has a greater magnitude than that of iodine?

Which of the following helps to explain why the electron affinity of Bromine has a greater magnitude than that of Iodine? There is greater attraction between an added electron and the nucleus in Bromine than in Iodine.

Why the electron affinity of BR has a greater magnitude than that of I?

There is a greater attraction between an added electron and the nucleus in Br than in I.

Which of the following best helps to explain why the electronegativity of CL is less than that of F?

Which of the following best helps explain why the electronegativity of Cl is less than that of F? The mass of the Cl atom is greater than the mass of the F atom. Because Cl is larger than F, the repulsions among electrons in the valence shell of Cl are less than the repulsions among electrons in the valence shell of F.

Which of the following best helps to explain why Na is more reactive with water than MG?

Explanation: A reactive metal has the ability to easily lose an electron and acquire a positive charge. Sodium easily loses electrons and acquires a positive charge. Sodium easily lose electrons than magnesium and get oxidized to easily.

Is Ca or Sr more reactive?

Calcium is less reactive than strontium or barium, forming a protective oxide-nitride coating in air that enables it to be machined in a lathe or handled by other standard metallurgical techniques. The chapter also illustrates the atomic and physical properties of alkaline earth metals.

Which one is more reactive Na or MG?

Magnesium is less active than sodium; calcium is less active than potassium; and so on.

What happens when phosphorus is kept in air?

When exposed to air, it spontaneously ignites and is oxidized rapidly to phosphorus pentoxide. Such heat is produced by this reaction that the element bursts into a yellow flame and produces a dense white smoke. Phosphorus also becomes luminous in the dark, and this property is conveyed to “tracer bullets.”
