Explain why an atom of any element is said to be electrically neutral. On the basis of electron configurations, explain why the electron affinity for iodine is lower than bromine Electrons in the 2s subshell are closer to the nucleus in which of the following nuclei? Explain. A...
Why are ionic compounds electrically neutral? Why do nonmetals form covalent bonds? Use VSEPR to explain why BH_3, NH_3 \space and \space FCl_3 all have different shapes even though they all follow the general formula of AX_3.
Isotopes of an element have same number of electrons and therefore, same valence shell electronic distribution. Since the chemical properties of the atoms are related to valence shell configurations, therefore isotopes are chemically similar.
particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral ...
Quantum mechanics states that among all the possible energy levels an electron can sit in the presence of a nucleus, there is one, which has THE MINIMAL energy. This energy level is called the ground state. So, even if atoms are in a very very called environment,QMprohibits electrons from...
Atoms:The smallest unit of any matter is known as an atom. Any matter is formed by the number of atoms binding together. Every matter, such as solid, liquid, and gas, contain neutral or ionized atoms. The diameter of the atom is in the pico-meter range....
The electrically charged particles then enter Earth's atmosphere, exciting gas atoms and molecules and generating auroras. The process is similar to how neon lights work: When the molecules and atoms get "excited" by electrons, they must return to their original energy (ground state) and do so...
Luckily, many atoms, including hydrogen and anti-hydrogen, have a “magnetic moment”. While they are electrically neutral and unresponsive to electric fields, they do act like little bar magnets and we can use that to keep them suspended. Even so...
Producing hydrogen takes energy because hydrogen atoms don't exist on their own — they are almost always stuck to another atom, often another element. (On earth, hydrogen is particularly abundant in the form of water, or H2O.) Creating pure hydrogen requires breaking those molecular bonds. ...
Neutral atmosphere Below about 100 km, or about 60 miles. (See the onlinedistance converter) Ionosphere Above about 100 km. Contains electrically charged particles or ions, created by the absorption of UV (ultraviolet) light. The degree of ionization varies with altitude. ...
