Helium is unable (really) to attract other electrons, so doesn't really have an electronegativity. Since it has a full outer shell, it cannot bond, so its electronegativity is irrelevant. Fluorine has …

If there are 14 electrons whizzing around a neutral atom, what element is the atom?

The atomic number for the element calcium (Ca) is 20. How many protons and electrons does each atom have? An atom has an atomic number of 79 and an atomic mass of 197. Once this …

If you have electrons in your If you have electrons in your equation, then a reduction has then on the LHS and the oxidation has them on the RHS. eg when Mg displaces Cu from Cu2+ the …

4.Electronegativity (a number that helps us understand the relative strength of attraction an atom has for electrons.) or the tendency of an element to attract electrons towards itself in a co …

The electronic configuration of Mg²⁺ is 1s² 2s²2p⁶. Magnesium is element 12 and belongs to Group 2 of the Periodic Table. An element in Group 2 has two valence electrons. It can achieve a …

What are the oxidation numbers in the compound H2O2? How can I find the oxidation number of transition metals? What is the oxidation number of a Group IIA element in a compound? What …

A reduction in the effective nuclear charge on the electron cloud, due to a difference in the attraction forces of the electrons on the nucleus Right, in an element we know that electrons …

It doesn't matter. It's Gallium, an element that you can see is using d orbitals. That allows it to store up to an additional 10 electrons, allowing it to have 18 electrons in its n = 3 set of …

We know that ionization potential or the first ionization potential is the energy required to remove the outermost electron from a neutral gaseous atom of an element. Similarly second and third …
