What elements has the greatest ionization energy Sodium Potassium Chlorine or Bromine?
Chlorine has the greatest ionization energy among these elements. This is because chlorine has the highest effective nuclear charge, making it more difficult to remove an electron from a chlorine atom compared to sodium, potassium, or bromine.
Which metal loses electrons most readily sodium or potassium?
Potassium loses electrons more readily than sodium due to its lower ionization energy and larger atomic radius. This makes potassium more reactive than sodium in terms of losing electrons to form positive ions.
Why is sodium nitrate more soluble than potassium nitrate?
Sodium nitrate is more soluble in water than potassium nitrate because sodium ions have a smaller size and higher charge density compared to potassium ions, which helps sodium nitrate molecules dissociate more easily in water. This results in more sodium nitrate ions being able to interact with water molecules and increase its solubility.
The amount of energy required to remove one mole of electrons from one mole of sodium atoms is the?
The amount of energy required to remove one mole of electrons from one mole of sodium atoms is known as the ionization energy. In the case of sodium, the first ionization energy is approximately 495.8 kJ/mol. This energy is needed to remove one electron from a sodium atom to form a sodium cation.
Why is sodium less reactive than potassium?
Sodium and potassium are both highly reactive because they have only one outer shell electron which they lose very easily to form Na+ and K+ ions respectively. The sodium and potassium in the body are already in the form of these ions.
What are the ionisation enthalpies of potassium and sodium?
The first ionization energy of potassium is 419 kJ/mol, while the first ionization energy of sodium is 496 kJ/mol. This means that it requires less energy to remove an electron from a potassium atom compared to a sodium atom.
What element has a lower ionization energy than Na?
Potassium (K) has a lower ionization energy than sodium (Na).
Does sodium have the larger first ionization energy than potassium?
No, potassium has a larger first ionization energy than sodium. Potassium has an extra electron in its valence shell compared to sodium, making it more difficult to remove an electron from a potassium atom compared to a sodium atom.
What element in family IA has the lowest ionization energy?
the lowest ionization energy in IA :hydrogen ,lithiun ,sodium and potassium
Which is more reactive francium sodium or potassium?
Francium is the most reactive alkali metal among francium, sodium, and potassium because it has the lowest ionization energy. Francium's reactivity increases moving down Group 1 of the periodic table. Sodium is more reactive than potassium due to sodium's lower ionization energy compared to potassium.
Which is more reactive sodium or barium?
sodium because it's the first group and first group are the most
What elements has the greatest ionization energy Sodium Potassium Chlorine or Bromine?
Chlorine has the greatest ionization energy among these elements. This is because chlorine has the highest effective nuclear charge, making it more difficult to remove an electron from a chlorine atom compared to sodium, potassium, or bromine.
Which of the elements sodium calcium potassium and magnesium has the smallest first ionization energy?
Potassium has the smallest first ionization energy among those elements listed. This is because potassium has the largest atomic size and the weakest attraction between its nucleus and outermost electron, making it easier to remove that electron.
Why k is more reactive than na?
Potassium (K) is more reactive than sodium (Na) because potassium has a lower ionization energy and a larger atomic radius compared to sodium. This makes it easier for potassium to lose an electron and form a positive ion, leading to greater reactivity.
Does calcium have a lower first ionization energy level than sodium?
No. Calcium has TWO valence electrons, and Sodium has ONE. It is lot easier to take off one, than two you see. However, the second ionization energy of calcium IS however than the second ionization energy of Sodium. ;)
What is first ionization energy?
Sodium's first ionization energy is 495 kJ / mol.
Sodium reacts with water more vigorously than potassium. why?
Sodium reacts more vigorously with water than potassium because sodium has a lower ionization energy and is more reactive. When sodium comes into contact with water, it forms sodium hydroxide and releases hydrogen gas, resulting in a more rapid and vigorous reaction compared to potassium.
