Ok an atom loses an electron becomes positive-atom gainin electron becomes negative? Is that correct? that's w/ 1 electron in outer shell of one atom and the other atom receiving an electron to fill its outer shell
That is correct. Electrons have a negative charge to them. Atoms typically have an equal number of protons, which are positive, to electrons. This makes the atom neutral. By losing an electron, and taking away a negative force, you weigh the atom on the positive side making it more positive. If you have an neutral atom and then gain another electron then you are adding a negative force which weighs it on the negative side.
Yes, you are correct! When an atom loses an electron, it becomes a positively charged ion, and when an atom gains an electron, it becomes a negatively charged ion. This process is known as ionization.
To understand why this happens, let's take a closer look at the structure of atoms. Atoms consist of a central nucleus, which contains protons and neutrons, surrounded by electrons. Electrons are arranged in energy levels or shells. The outermost shell is called the valence shell, and it determines the atom's chemical properties.
Atoms are most stable when their valence shell is complete, which usually means having 8 electrons. This is known as the octet rule. Atoms with incomplete valence shells are more likely to gain or lose electrons to achieve a stable configuration.
In your example, if an atom has 1 electron in its outer shell, it will be more stable if it loses that electron and has a complete valence shell. When an atom loses an electron, it becomes a positively charged ion because it now has more protons than electrons, resulting in a net positive charge.
On the other hand, if another atom that has an incomplete valence shell receives an electron, it will become more stable by filling its outer shell. When an atom gains an electron, it becomes a negatively charged ion because it now has more electrons than protons, resulting in a net negative charge.
It's important to note that not all atoms need to gain or lose only one electron to achieve a stable configuration. The number of electrons gained or lost depends on the specific atom and its position on the periodic table.
So, in summary, when an atom loses an electron, it becomes a positive ion, and when an atom gains an electron, it becomes a negative ion. This electron transfer occurs to achieve a stable electron configuration in the valence shell.
