Atoms are most stable when their electron shells are full, but most elements have electrons to spare. This is the driving force behind the chemistry we see around us. To complete half-filled shells, atoms form chemical bonds. They can either share their electrons to form covalent bonds, or ...
a device is used to accelerate neutrons toward the nucleus of an atom. The collision of the neutrons with the atom causes the atom’s nucleus to break apart into fragments. Each fragment is roughly half the mass of the original atom. ...

and the atoms are more stable when these shells are filled. It is possible to predict which charge an atom will gain by looking at the how the electrons sit around the atom. The first shell of an atom can only hold two electrons, the second shell...
The isotopic mass is referred as mass of the most abundant isotope of an element. The relative isotopic mass of an isotope mass of one atom of the isotope = 12 x mass of one atom of 12C
in ionic compounds, the metal atom donates electrons while the nonmetal atom accepts them. so, in the case of the nacl compound, sodium (na) is the metal that will give away the one electron and forms na + ion, whereas chlorine is the non-metal that will accept the one electron and ...
How is tin formed? A Type of Metal: Tin is an element that is considered to be a post-transition metal, or a poor metal. These are metals that are softer and weaker than many others. Tin is element number 50 on the periodic table, with symbol Sn. Tin is the 49th most abundant me...
then it is easier for an atom to lose electrons in order to become more stable. In this case, the atom becomes a positive ion. Alternatively, if a shell is more than half full, it is easier for an atom to gain electrons in order to become more stable. This leads to a negative ion...
If we remove an electron from a stable atom, the atom becomes electrically incomplete/unbalanced. That is, there are more protons in the nucleus (positive charges) than there are electrons (negative charges). With an electron removed, the atom possesses a plus one charge, therefore it is a...
Most elements have very stable atoms which are impossible to split except by bombardment in particle accelerators. For all practical purposes, the only natural element whose atoms can be split easily is uranium, a heavy metal with the largest atom of all natural elements and an unusually high ne...
