1. Why is the ionization energy of helium greater than that of the other elements? Explain why a soft-iron core increases the strength of an electromagnet. What is one of the most efficient techniques to determ
What is the relationship between electronegativity and bond type? Which of the alkaline earth metals has the smallest electronegativity? What does einsteinium bond with? Do nonmetals have high electronegativity? What is the ionization energy of beryllium?
Parallel configuration, that is, the total spin is 1 Anti-parallel configuration, that is, the total spin is 0Answer and Explanation: Of the two spin states of a neutral Hydrogen atom, the parallel configuration has a slightly higher energy than the antiparallel configuration. When...
It's the best evidence yet for the force behind reionization, but there's more work to be done. The researchers looked at one small patch of the sky; they need to make sure that their sample isn't just an anomalous cluster of dwarf galaxies, but is a representative sample of the enti...
If an atom has an atomic number of 8, how many protons will it have? Which element has the highest atomic number? What is a helium-4 atom with no electron? What is the atomic mass/weight of an atom that has 24 protons, 26 neutrons, and 24 electrons? What element has the same numb...
Traditionally, plasma cleaning has been conducted in a vacuum chamber or a similarly controlled environment. In this setup, a gas such as argon, oxygen, hydrogen, or helium is introduced into the chamber before the electrical field or energy is applied. ...
In addition, we now know that alpha particles are the nuclei of helium-4, containing two protons and two neutrons, and as we shall see later, they can be the product ofradioactive decay. Electrons in the atom As we have seen, the number ofelectrons spinningaround a nucleus is usually th...
The Mulliken scale simply considers the electronegativity of an element as the average of the ionization potential and the electron affinity of that element.
Indicate the number of unpaired electrons in the ground-state atom it has 2 unpaired electrons in the 4P orbital. in a chemical reaction it is likely to take 2 electrons & become Se-2 or likely to do 2 covalent bond with other atom. it is also likely to lose all 6 electrons in its...
What is the name of the Li element? 1. Why is the ionization energy of helium greater than that of the other elements? Although fluorine is the most electronegative element, silicon tetrafluoride (SiF_4) does not have-a dipole moment. Explain. ...
