Chlorine will gain one electron when it forms an ion to be an anion with a charge of -1. How Na and Cl lose and gain electrons? The most common example is sodium chloride, NaCl. In this compound each sodium atom has lost one electron (giving it a charge ofRead More →
An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. … Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals. Do ionic bonds transfer electrons? The attractionRead More →
Electron Domain – The region in which electrons are most likely to be found (bonding and nonbonding). A lone pair, single, double, or triple bond represents one region of an electron domain. H2O has four domains: 2 single bonds and 2 nonbonding lone pairs. Electron Domain may also be referredRead More →
Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom. Why is the numberRead More →
For finding the number of unpaired electrons, then first we have to find the atomic number of the element then write the configuration in the ground state, then according to the oxidation state subtract the number of electrons from the outer shell. So, there are 4 unpaired electrons. So, thereRead More →
Metalloids and some metals can be can lose or gain electrons. This is not always true, as elements such as nitrogen can lose electrons to become positive. When an ionic compound forms, the more electronegative element will gain electrons and the less electronegative element will lose electrons. What is theRead More →
Which organelle contains cristae where enzymes and electron carriers for aerobic respiration are found? chloroplasts. use them to expel excess water from the cell. anchors organelles. Which organelle is found in algae but not found in helminths or fungi? All algae have chloroplasts. Which organelle is found in algae butRead More →
Selenium is a chemical element with the symbol Se and atomic number 34. What element has 34 protons and 46 neutrons? Selenium (Se). Diagram of the nuclear composition and electron configuration of an atom of selenium-80 (atomic number: 34), the most common isotope of this element. The nucleus consists ofRead More →
A complete octet is very stable because all orbitals will be full. Atoms with greater stability have less energy, so a reaction that increases the stability of the atoms will release energy in the form of heat or light. Octet Rule. A stable arrangement is attended when the atom isRead More →
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron. What happens to electrons in anRead More →
