When an atom becomes an anion..what happens to its radius?
okay so the atom is the same (since protons don't change, only electrons) when it becomes an anion, it gains electron(s). therefore there are more electrons around nucleus. So then the pull on each original electron is less, because there are more electrons to be pulled on. So the pull/attraction becomes less, so the atomic radius gets larger, because not as strong.
What happens when an atom becomes an ion?
The atom becomes charged; either positively by loosing an electron or negatively by gaining an electron. The charge alters the atom's interactions with other atoms and molecules (and light, too - electromagnetic radiation). Unless the atom is in a near vacuum it rapidly becomes surrounded by other atoms or molecules which are polarized so that the charge is "protected"...kind of like a crowd of fans around a celebrity, if they were walking by you would only catch glimpses of the celeb thru the crowd. ANyway, before that even happens, in fact almost instantaneously, the orbits of the other electrons around the nucleus change (actually, this happens as the electron move towards the atom or away from it). A positive ion is positive because the nuclear charge from the protons is not canceled by the opposite charge from the (no longer) equal number of electrons orbiting it giving a net positive charge. The orbits of the remaining electrons shrink closer to the nucleus because the "pull" on each of them is a little stronger, on average. Just the opposite happens when an atom gains an electron: it gets bigger - meaning that the electrons push away from each (repell) other so the orbits around the nucleus get a little bigger.
What Happens When a Metal Atom Loses an Electron?
When a metal atom loses an electron it is dispersed into the electron gas which pervades the metal lattice and contributes to metallic bonding. The partially +vely charged kernels are glued together by the electrons. It is only when an individula atom loses an electron are cations formed. Ask in a snobbish way, be answered in like :)
Explain what happens to an atom when you change the following?
When you change: a. number of protons: you will change the atom from one element to a different element. For example if you add a proton to an atom of the gas neon 22, you will change it to an atom of the metal sodium 23. In this example both atoms are stable, but the result of adding a proton is often to make the atom unstable, and it will decay to some other element after a period of time. For example if you added the proton to an atom of neon 21, it would make an atom of Sodium 22 which is radioactive. Half the atoms of sodium 22 will decay within 2.6 years. b. number of neutrons: you get an isotope of the same element. Isotopes are chemically similar but physically slightly different. For example if you add a neutron to an atom of neon 21, you will get an atom of neon 22. Again the addition may make the atom radioactive. c. number of electron: you will get an ion of the element. For example when salt is dissolved in water, each atom of sodium loses an electron to an atom of chlorine, and goes into solution as a positively charged ion of sodium. The solution as a whole is electrically neutral because the positively charged sodium ions are offset by the negatively charged chlorine ions.
How does an atom of a metal become an ion?
Metals tend to lose their valence electrons to attain the electron configuration of the nearest noble gas. For metals such as the alkali metals and the alkaline-earth metals, just look at the atomic number. How much is the atomic number reduced to go back to the nearest noble gas? The alkali metals always lose one electron, so their charge is one positive. The alkaline-earth metals always lose two electrons, so their charge is two positive.
Nothing. The actual mass of the atom will change by about the mass of an electron, but Mass Number is a term defined by the number of nucleons. That doesn't change with ionization.
What happens when a nonmetal atom forms an ion?
An nonmetal atom always has 5, 6, 7 electrons in its outer-most shell so it always accepts electrons, so it will become negatively charged ion which is called anion and the won't have any change I guess or maybe size would increase as electro-static force of repulsion would increase between nucleus and valence shells. And lose of electrons is only done by metals who have 1, 2, 3, 4 electrons in outermost shell.
The microstructure of metals is an orderly arrangement of the atoms into a lattice arrangement. Depending on the size of the atoms, they stack and bind together into arrangements that are characterized by the stacking arrangement .Some metals form simple cube arragngement of the atoms, and others have cubes with a single atom in the center of the cube, and some are arranged with atoms at the center of each cube face…some are hexagonal and so on.These lattice arrangement form crystals , and often they all all orientred a bit different and each domain orientation forms a crystal we call a grain.Where two grains meet, there is boundary with some mis -matched lattice atoms and they are basically holes ... places where the atoms dont want to be, because of the energy state. The mismatched spaces are called dislocations, and intially allow the material to form ( bend) easier than a orders crystal, as the dislocations move.Bending will result in some atoms or planes slipping past each other creating some more dislocations that tangle things up abitThese tangles of dislocations result in strengthening the material as they block further movement and opin some of the atoms in place — this is called work hardeningI dont think much goes on within an atom during bending, pehaps some electrons jumping to outer rings as they absorb energy, and fallimg back generating some heat, but the lattice they form surely undergoes changes as noted above.
Basically, its oxidation state changes; you get the removal of one or two or more electrons (depending on whatever acid/bases/substance attacked this metal) close to the electron cloud; the result is an ion, or more specifically, a cation.If you do mean what happens whenever acid attacks a metal particle, within its own lattice, then I could only elaborate as I am not completely common with such studies. But I would like to give it a try:Considering an upcoming proton for example, the reaction of oxidation should remove the bond between the atom on the surface of the lattice, and therefore release the atom from the lattice. What would result is the ion now floating on an aqueous solution for example, or reacts with oxygen/hydrogen forming another compound.
It becomes an Ion. Ions are of two types:-Cations- They have a deficiency of electrons, as they donated it to another atom. Thus they have a positive charge (more protons than electrons- & protons have a [+ve] charge).Anions- They have an excess of electrons, as they accepted electrons from another atom. Thus they have a negative charge (more electrons than protons & electrons have a [-ve] charge).Kindly do not hesitate to message if any other queries… :)Hope this helps :) ☮️
