WebJun 16, 2016 · Explanation: If we assume that the atom of our mystery element is neutral, then the number of electrons is equal to the number of protons. The number of protons is the atomic number, which being 47 identifies this element as Silver (Ag). However, if we allow for charged atoms, in other words ions, then the answer is not definite. If we look at ... WebWell, the first thing that I would say is, well look, they tell us that this is fluorine. As soon as you know what element we're dealing with, you know what it's atomic number is when you look at the periodic table and you can figure out the number of protons. Remember, your atomic number is the number of protons and that's what defines the ...
How do atoms become ions? Socratic
When writing the chemical formula for an ion, its net charge is written in superscript immediately after the chemical structure for the molecule/atom. The net charge is written with the magnitude before the sign; that is, a doubly charged cation is indicated as 2+ instead of +2. However, the magnitude of the charge is omitted for singly charged molecules/atoms; for example, the sodium cation … WebJul 29, 2024 · The present study is focused on the development of a material model where the orthotropic-visco-elastic and orthotropic-visco-plastic mechanical behavior of a polymeric material is considered.
