(A) atom as a whole is electrically neutral. (R)atom contains equal amount of positive and negative charges. Aif both assertion and reason are true and reason is the correct explanation of assertion. Bif both assertion and reason are true but reason is not the correct explanation of asse...
An atom is normally electrically neutral. Why, then, should an alpha particle be deflected by the atom under any circumstances?Alpha ParticlesAlpha particles are made up of 2 protons and 2 neutrons. A proton has a +1 charge while a neutron ...
Why do elements in group 1 become more reactive the further they are down the group? Why are ionic compounds electrically neutral? Why do multiple covalent bonds form? What are some uses of nonmetals? Why do covalent bonds form? What are the properties of nonmetals?
Every matter, such as solid, liquid, and gas, contain neutral or ionized atoms. The diameter of the atom is in the pico-meter range.Answer and Explanation: Atoms do not collapse because there is no empty space in atoms, the space is always filled with a wide variety of particles and fi...
Fthe molecules formed by sharing of electrons between two or more same atoms or between two or more non-metals are called covalent compounds. Characteristics of covalent compounds : (i) Covalent compounds usually have low melting and boiling points as they are formed by 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...
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. ...
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. ...
Needless to say, this is a difficult calculation. For the computer to record the data of even a few electrons, its memory needs more atoms than there are in the entire universe, and with the addition of only a few more particles, the complexity goes up exponentially. ...
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.
