How do you determine the number of valence electrons in an element? How do the number of valence electrons relate to an element's chemical properties? How do valence electrons affect …

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 …

31 protons, 31 electrons and 40 neutrons. The atomic number of gallium is 31, which means it has 31 protons. If it is neutral the number of electrons is the same. The number of neutrons is the …

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 …

A nuclear reaction however, does not involve electrons, but involves the nucleus (hence the term "nuclear"). The reaction happens inside the nucleus, where protons and neutrons react with …

A new element has the symbol #Y# and seven valence electrons. What is the maximum number of hydrogen atoms that can bond to it? What is the slope of the equation #-6x+13y=-2#? A …

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 …

Re: Ap Free responce help. isotopes and ionization help in terms of the atomic structure, every atom of selenium will have 34 protons (it is the protons that determines the identity of the …

But we do this for hydrogen peroxide, H O− OH, we break an oxygen-oxygen bond...and here the electrons are conceived to be shared to give: H O− OH → 2 ×.

If you look at the location of aluminium you will note that it is right next to the metalloids which are elements that share characteristics of metals and nonmetals. In general, the further the metal …
