What is the charge of an atom with 18 electrons? – WisdomAnswer
Web12 jul. 2024 · If an ion has a 2+ charge then it must have lost electrons to form the cation. If the ion has 18 electrons and the atom lost 2 to form the ion, then the neutral atom contained 20 electrons. Since it was neutral, it must also have had 20 protons. Therefore the element is calcium. What is an anion with 18 electrons? Web12 jul. 2024 · If an ion has a 2+ charge then it must have lost electrons to form the cation. If the ion has 18 electrons and the atom lost 2 to form the ion, then the neutral atom … dicks hydro flask coupon

WebWe can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+ (-8) or 8-8. Eight minus eight equals zero, which is neutral. Basically, a "neutral atom" is an atom that has the same amount of protons as it does electrons. WebThis results in a cation with 20 protons, 18 electrons, and a 2+ charge. It has the same number of electrons as atoms of the preceding noble gas, argon, and is symbolized Ca 2+. The name of a metal ion is the same as the name of the metal atom from which it forms, so Ca 2+ is called a calcium ion. Web25 apr. 2024 · Argon has 18 protons and is a neutral atom, so it also has 18 electrons. What element has 18 electrons and a net charge of? Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons, giving it a net negative ... citrus fruit as hand sanitizer
