WebIt is because of the shielding effect that the ionization energy decreases from top to bottom within a group. From this trend, Cesium is said to have the lowest ionization energy and … WebWhen an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion. What ...
Fe^+3 is more stable than Fe^+2 , the reason is/are: - Toppr
Web24 nov. 2024 · The more you can spread charge around, the more stable an ion becomes. In this case, if you delocalise the negative charge over several atoms, it is going to be much less attractive to hydrogen ions - and so you are less likely to re-form the ethanoic acid. Phenol Phenols have an -OH group attached directly to a benzene ring. WebIn covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail. Covalent bonds and molecules A covalent bond is formed when two atoms share electron pairs. daily face lotion with sunscreen
Give reason for the following : a) Ions are more stable …
Web26 aug. 2024 · Assertion : The lesser the lattice enthalpy more stable is the ionic compound. Reason : The lattice enthalpy is greater, for ions of highest charge and smaller radii. Answer Answer: (d) Assertion is false but reason is true. The greater the lattice enthalpy, more stable is the ionic compound. Q.3. Web8 mrt. 2013 · d) Nucleus of an atom contain sprotons and neutrons, which are bulkier than electrons.Also, proton has +ve while neutron has no charge. so, overall charge is +ve. e) … Web8 apr. 2024 · The delocalization of the positive charge is the main reason. Due to delocalization, the electron deficiency is decreased and the stability is increased. In comparison, the resonance effect is a more dominating factor than substitution. The structures with resonance are better stabilized than others. daily face moisturizer for combination skin
