4.Imagine and write what type of ion can be formed generally by an atom ofelement with low ionisation energy, low electron affinity with high atomicsize ?

Answer»

Atoms can gain or lose electrons. When an atom gains an electron, energy is given off and is known as the electron affinity.Electron affinityis defined as the energy released when an electron is added to a gaseous atom or ion.When most reactions occur that involve the addition of an electron to a gaseous atom, potential energy is released.

plants with weak stems generally possess tendrils
