The electron affinity is the potential energy change of the atom when an electron is added to a neutral gaseous atom to form a negative ion. So the more negative the electron affinity the more favourable …

Electron Affinity Chemistry Questions with Solutions Q-1: The process requires absorption of energy is F→F – Cl→Cl – O – →O 2- H→H – Answer: c) O – →O 2- Explanation: Addition of an electron to an …

Electron affinity is defined as the amount of energy liberated when a molecule or neutral atom acquires an electron from outside. This property have a fixed and measurable value. Below are the key …

What Is Ionization Energy? Ionization energy or Ionization enthalpy of elements is defined as the amount of energy required by an isolated gaseous atom to lose an electron in its ground state. Losing of …

The systematic arrangement of elements in a periodic table discloses certain periodic trends in the properties of elements. For example, atomic radii and ionic radii decrease from left to right, moving in …

What is the difference between electron affinity and electronegativity? The difference between the two is that electronegativity is a chemical property that shows how well an atom can attract electrons to …

Electronic configuration Atomic radius Nuclear charge. Electron affinity means love for electron. It is the negative of the electron gain enthalpy. By using the concepts of thermodynamics, we find a …

The correct option is D Cl, Cs Explanation for Correct option: Option- D) Chlorine (Cl) is the element with highest electron affinity in the periodic table because of the presence of 7melectrons in the valence …

Electron affinity is the amount of energy released when an electron is added to a neutral atom to form an anion. The measurement of electron affinities is difficult.

As the size or the radius of the atom increases, the ionization enthalpy decreases (it is easier to remove an electron from an atom with a large atomic radius since the distance between the nucleus and the …
