Which element has the same number of valence electrons as phosphorus? Which element will most likely gain electrons? a. Cl b. Na c. Ne Why? What is an atom that has more protons than electrons? What element has 10 electrons? What element has 13 electrons?
When electrons are added or removed from an atom of an element, a charged species is formed known as ions. Answer and Explanation: Metals can lose electrons to complete their octet and forms cations whereas non-metals gain electrons to co...
To determine which atom does not have any neutrons, we can follow these steps:1. Understand Atomic Structure: - An atom consists of protons, neutrons, and electrons. - The atomic number (Z) represents the number of proton
aThen, Rutherford himself proposed the orbital model for the atom, in which there was a central nucleus populated by positively charged particles – protons – and negatively charge particles – electrons – moving around the nucleus 正在翻译,请等待... [translate] ...
