What happens when chlorine atoms gain an electron in its outer energy shell?
what happen when an atom what has a lot of electron comes in contact with an atom that has gained an electron
What subatomic particle occupies the most volume in the atom?
the vast majority of the volume of an atom is filled with absolutely nothing there is a central heavy nucleus and "whizzing" round it are a number of much lighter much smaller electrons. from the outermost reaches of the electrons orbits to the centre of the nucleus there is an awful lot of "nothing" an analogy is to consider the earth we are a heavy central body - compare us to the nucleus of an atom whizzing round us are various satellites - the moon and many small artificial ones we have put up - compare them to the electrons in between and making up by far the bulk of the volume occupied by the "earth and its satellites" is a lot of nothing - just like in an atom
Why do electrons make up much of an atoms volume but not its mass?
An atom is the smallest particle of an element, but it also has the strongest charges, which causes it to be repulsed further from the protons and neutrons, thus causing greater volume. However, the volume of the electron itself is so small that it is negligible, also, google point masses to learn about this second point.
Are atomic nuclei mostly empty?
yes. The distance between the Nucleus and an electron cloud varies from atom to atom (element to element). think of a basket ball as the nucleus. The 1st electron cloud could be as far as 1-5 km away. A lot of empty space
What change in electron structure occures when a sodium atom becomes a sodium ion?
The valence electrons are either lost to another atom or the sodium atom gains valence electrons, it really depends on if what the sodium atom is bonding with has a lot or a little of valence electrons. The structure doesn't change though, just the number of valence electrons change. The nucleus is never changed when an ion is formed.
Valence electrons determain an atom's?
Your question doesn't really ask anything. The electron states of atoms can determine a lot of things, please be more specific.
What is the charge and the name given to an atom that loses electrons?
when an atom loses an electron it becomes positive because it just lot a negetive part to its structure. The name given to these positively charged particles is Cation
Why did Thompson choose a circle for his first model of the atom?
The electron will always be the same distance from the nucleus. If there is a heavy part, it makes sense that it will be in the middle so that the atom will be symmetrical. Solar systems are similar in that there is a dense part and a lot of empty space with the sun in the middle.
Most mass of an atom is located where?
Nearly all of an atom's mass is located in its nucleus, which holds an atom's heaviest particles, protons andneutrons The electrons in its Electron Cloud have nearly no mass so they are not counted.
What is the relationship between radium and its ionization energy?
The relationship between radium and its ionization energy is that radium has a high ionization energy. This means that it requires a lot of energy to remove an electron from a radium atom.
Is the mass of an atom found in the nucleus of an atom?
Yes, most of the mass of an atom is found in the nucleus. If you consider that a proton is over 1800 times more massive than an electron, it might come into focus. The neutron is just a tiny bit heavier than that proton. A single nucleon, which is the term we give a proton or neutron residing in the nucleus of an atom, will far, far outweigh all of the electrons that could possibly be around it. And by a factor in excess of 103, too. No, there isn't a lot of mass in the electron cloud as a whole.
How can a object have a lot of mass but a little volume?
An object can have a lot of mass but little volume if the particles making up the object are densely packed together. For example, a material like lead is very dense, so even a small volume of lead can have a lot of mass. This can result in objects that are heavy but take up little space.
