Chlorine has the higher ionization energy compared to sodium. This is because chlorine has a larger number of protons in its nucleus, creating a stronger positive charge that holds its electrons more tightly.
Chlorine has a higher ionization energy than sodium. This is because chlorine has a smaller atomic size and higher effective nuclear charge, making it more difficult to remove an electron compared to sodium.
No, fluorine has a higher ionization energy than chlorine. Fluorine is the most electronegative element in the periodic table, meaning it has a strong attraction for electrons and therefore requires more energy to remove an electron compared to chlorine.
Calcium fluoride has a higher melting point than chlorine fluoride because the calcium ion has a higher charge density than the chlorine ion, leading to stronger electrostatic forces of attraction between the calcium and fluoride ions in the lattice structure. This results in a greater amount of energy required to break these bonds, leading to a higher melting point for calcium fluoride compared to chlorine fluoride.
Fluorine has a higher melting point than chlorine because fluorine atoms are smaller and have stronger London dispersion forces due to higher electron density, making the intermolecular forces stronger and requiring more energy to break the bonds between the fluorine atoms.
The enthalpy of Cl2 (chlorine gas) is higher than 2 Cl (two atoms of chlorine). This is because forming Cl2 from two Cl atoms involves the breaking of an existing bond between the atoms, which requires energy input, whereas 2 Cl atoms do not require this bond formation energy.
Ionisation energy differs between elements due to variations in the number of protons in their nucleus, which affects the strength of the attraction between the electrons and the nucleus. Elements with higher atomic numbers typically have higher ionisation energies due to increased nuclear charge. Additionally, ionisation energy generally increases across a period and decreases down a group on the periodic table.
Chlorine has a higher ionization energy than sodium. This is because chlorine has a smaller atomic size and higher effective nuclear charge, making it more difficult to remove an electron compared to sodium.
1.A small atomic/ionic radius 2.therefore less number of protons 3. more net nuclear attraction between the positively charged nucleus 4. higher energy is needed to break those bonds. 5. therefore an element has high ionisation energy
The second ionization energy of sodium is so much greater than the first because the first electron is removed from the valence shell, while the second electron is removed from the core orbitals. Additionally, the sodium atom has a positive charge after the first ionization, which thus attracts the remaining electrons more strongly. Both of these factors lead to a much higher second ionization energy compared to the first.
Chlorine has a higher ionization energy than sodium. This is because chlorine, being a halogen, has a stronger electron affinity and is closer to achieving a stable electron configuration by gaining an electron, leading to a higher energy needed to remove an electron from its outer shell.
The ionisation enthalpy of potassium is lower than that of sodium.
No, fluorine has a higher ionization energy than chlorine. Fluorine is the most electronegative element in the periodic table, meaning it has a strong attraction for electrons and therefore requires more energy to remove an electron compared to chlorine.
No, sulfur has a higher ionization energy than chlorine. Ionization energy is the energy required to remove an electron from an atom, and it generally increases across a period from left to right. Chlorine, being to the right of sulfur in the periodic table, has a higher ionization energy.
Yes, chlorine has a higher ionization energy than aluminum. Ionization energy generally increases across a period in the periodic table due to increasing nuclear charge and decreasing atomic radius. Chlorine is located to the right of aluminum in the periodic table, making its ionization energy higher. Specifically, chlorine's ionization energy is about 1251 kJ/mol, while aluminum's is around 577 kJ/mol.
Argon has a higher ionization energy than chlorine. This is because argon is a noble gas with a full valence shell, making it more stable and harder to remove an electron from compared to chlorine which is a halogen with one electron missing from a full octet.
Calcium fluoride has a higher melting point than chlorine fluoride because the calcium ion has a higher charge density than the chlorine ion, leading to stronger electrostatic forces of attraction between the calcium and fluoride ions in the lattice structure. This results in a greater amount of energy required to break these bonds, leading to a higher melting point for calcium fluoride compared to chlorine fluoride.
Fluorine has a higher melting point than chlorine because fluorine atoms are smaller and have stronger London dispersion forces due to higher electron density, making the intermolecular forces stronger and requiring more energy to break the bonds between the fluorine atoms.
