How many electrons do h and he have
WebNov 4, 2024 · You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the real behavior of electrons is less simple. Here is a table of element valences. WebThe Balmer series—the spectral lines in the visible region of hydrogen's emission spectrum—corresponds to electrons relaxing from n=3-6 energy levels to the n=2 energy level. Bohr could now precisely describe the …

WebOne carbon atom forms four covalent bonds with four hydrogen atoms by sharing a pair of electrons between itself and each hydrogen (H) atom. The electronegativity value for carbon (C) and hydrogen (H) is 2.55 and 2.1 respectively, so the difference in their electronegativity values is only 0.45 (<0.5 criteria); the electrons are thus equally ... WebMar 6, 2024 · So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together. Whichever you know, you subtract from the atomic mass. Thanks! We're glad this was helpful.
