The element with the lowest enthalpy of atomization is usually helium. This is due to its complete outer electron shell, resulting in a very stable atomic structure. Helium exists as individual atoms with negligible interactions between them, requiring minimal energy to separate them into individual atoms compared to other elements that have stronger interatomic forces or bonds.

What is the relationship between enthalpy of atomisation of hydrogen and the bond dissociation enthalpy of the H-H bond?
the enthalpy of atomisation of hydrogen is equal and (in principle) identical to the bond dissociation enthalpy of the H-H bond. However, IF the first is measured by calorimetry and the second by spectrometry there might be a systematic difference.
Which element has the lowest number of electrons?
Hydrogen, the element with the lowest atomic number.
Why does oxygen gas not have an enthalpy of formation but ozone does?
Oxygen gas (O2) does not have an enthalpy of formation because it is an element in its standard state, which has an enthalpy of formation of zero by definition. Ozone (O3), on the other hand, is a compound and has a defined enthalpy of formation because it is formed from its elements in their standard states.
What element has the lowest electronegative?
Barium
What element has the lowest atomic number in period 3?
The element with the lowest atomic number in period 3 is sodium (Na) with an atomic number of 11.

What is the different between iodine in enthalpy in atomisation and enthalp y of sublimation?
i believe that standard enthalpy change of atomisation is the enthalpy change that takes place when one mole of gaseous atoms is formed from its elements under standard conditions(which includes breaking of bonds between atoms within molecules), while for sublimation it only involves the change of states (from solid to liquid) with no intramolecular bonds broken.
Which element has the lowest number of electrons?
Hydrogen, the element with the lowest atomic number.
What element has the lowest dencity of all the elements?
The element with the lowest density is hydrogen.
Why does oxygen gas not have an enthalpy of formation but ozone does?
Oxygen gas (O2) does not have an enthalpy of formation because it is an element in its standard state, which has an enthalpy of formation of zero by definition. Ozone (O3), on the other hand, is a compound and has a defined enthalpy of formation because it is formed from its elements in their standard states.
Why transitional elements have high enthalpy of atomisation?
Transition metals possess a high melting points and boiling points.These properties are due to mettalic bonding by delocalized electrons,leading to cohesion which increases with the number of shared elements.
What element is the lowest density of all element?
hydrogen
What is the element with the lowest oxidation state on the periodic table?
The element with the lowest oxidation state on the periodic table is Francium.
Which element has the lowest mass on the periodic table?
The atom that has the lowest mass is hydrogen. So assuming the same numbers of atoms in each element, hydrogen would be the element with the lowest mass.
What element has the lowest electronegative?
Barium
Which solid element has the lowest density?
The solid element that has the lowest density is lithium. Its density is 0.534 grams per cubic centimeters. Lithium is a metal, and it does not occur freely in nature.
What element has the lowest electrogravity?
Helium has the lowest electronegativity among all elements.
