Ionization enthalpy is defined as the energy change in the process when the outermost electron is lost from an atom in the gaseous state. Electron Affinity is defined as the energy change in the process when an additional electron is ...
Theneutron isslightlyheavierthan theproton. This increases the mass of nuclei with more neutrons than protons relative to the atomic mass unit scale based on12C with equal numbers of protons and neutrons. Thenuclear binding energyvaries between nuclei. A nucleus with greater binding energy has lower...
The impact on human health is poorly understood and it is impossible to say what level of dietary exposure to acrylamide can be deemed safe as the assessment of exposure is uncertain. The determination of hemoglobin (Hb) adducts from acrylamide is increasingly being used to improve the exposure ...
Step 2: Understand Enthalpy of FormationThe enthalpy of formation (ΔH_f) of a compound is the change in enthalpy when one mole of the compound is formed from its elements in their standard states. For alkali metal fluorides, this involves the formation from the metal and fluorine gas. Step...
Electronegativity is an atom's tendency to attract electrons to itself in a chemical bond. The most electronegative element is fluorine. The least electronegative or most electropositive element is francium. The greater the difference between atom electronegativity values, the more polar the chemical bo...
The Element Lithium Lithium is a chemical element that is abbreviated 'Li.' Its name comes from the word 'lithos,' which is a Greek word that means 'stone.' Answer and Explanation: The mass number of lithium is 7. The mass number of any element is equal to its number of protons and...
In the presence of oxidants (NaNO3, NaNO2, KClO3, PbO2), the reaction to form tungstate is more violent. It can combine with oxygen, fluorine, chlorine, bromine, iodine, carbon, nitrogen, sulfur, etc. at high temperature, but not with hydrogen.The following is the reaction equation of tun...
What do fluorine and chlorine have in common? What do halogens like to react with? What do halogens react to form? What is the difference between halogens and chalcogens? How do halogens form compounds? What is the charge of halogens?
