it becomes an ion.
an ion of any element has the same number of protons but different number of electrons.
an ion can be of two types. cation and anion. cation is positive i.e. one less electron and an anion is negative, i.e. one more electron.
so that's the answer to your original question. if an electron is added, the atom of the element becomes negatively charged.
If you add a Negative Election (e-) to Atom, the Atom will become a negative isotope, Atom with the same Atomic Number But Different Mass Number.
Nothing major, it would just become more or less polarized.
if an electron is added, the atom becomes negative
if an electron is subtracted, the atom becomes positive
You would get, of course, either lead or mercury
B
Electrons are transferred from one element to another. when electrons are shared this is a covalent bond.
The element that has a single electron in the 2p sublevel is boron. The electron configuration of Boron is 1s22s22p1.
The electron configuration of the element with the atomic number 39 (yttrium) is: [Kr]4d15s2.
when an electron is added to an atom, the atom will acquire a negative charge.
The ATOM decreases in size when it loses an electron and increases when electrons are added.
You would get, of course, either lead or mercury
Because the electron is a lepton, and is not made of quarks.
B
the atom becomes negatively charged
you cant add proton to an atom...u can only add electron....
Electrons are transferred from one element to another. when electrons are shared this is a covalent bond.
Helium has no electron affinity.
An electron is not an element.
The electron affinity of yttrium is 29.6 kilojoules per mole. This is how much energy this element releases when added to a single neutral, gaseous molecule or atom to create a negative ion.
The element that has a single electron in the 2p sublevel is boron. The electron configuration of Boron is 1s22s22p1.
