In general chemical reactions, metals tend to loose electrons and non-metals gain electrons. The no. of electrons loosed by metals is the same as the no. of electrons gained by the non-metals.
The outermost, known as the valance electrons.
Phosphorous has 5 electrons in its valence shell.So, it needs to borrow 3 electrons to attain an octet of electrons. However, this rarely happens as phosphorous forms bonds by covalent bonding in general.
The most basic categories of the elements found in the periodic table would be metals which tend to donate electrons in a chemical reaction, non-metals which tend to receive electrons in a chemical reaction, and noble gases which don't engage in chemical reactions. You could count the number of elements in each category and then have a pie chart with 3 slices. One observation that you could make with such a chart is that there are a lot more metals than there are elements of the other two categories combined. There are also other possible pie charts, such as radioactive elements vs. stable elements, or categorizing elements according to their phase (which is solid, liquid, or gas) at room temperature and normal air pressure. (Most elements are solids.)
The properties of a substance include: what is its phase (solid, liquid, or gas) at room temperature, or at other temperatures; what is its melting point and boiling point; what is its electrical conductivity, its solubility in water or in other solvents, its hardness (in the case of a solid - and anything except for helium can be solid, if the temperature is low enough), what is its chemical reactivity, does it tend to donate electrons or receive electrons when it undergoes a chemical reaction, what kinds of bonds does it tend to form, how dense is it at room temperature, and of course, the old favorite, what is its color, etc.
To the intermembrane space
Nitrogen is a nonmetal with 5 valance electrons, which tends to receive three electrons to complete it outer electron shell.
The outermost, known as the valance electrons.
Metallic chromium atoms tend to lose electrons in a chemical reaction. The chromium in a compound may either gain or lose, depending on the reaction.
Yes. Metals lose their valence electrons to form cations, or positive ions. Once they lose electrons, the number of protons in their nuclei outnumber the electrons, hence the positive charge.
Phosphorous has 5 electrons in its valence shell.So, it needs to borrow 3 electrons to attain an octet of electrons. However, this rarely happens as phosphorous forms bonds by covalent bonding in general.
An ion can give and receive electrons
Metals have a characteristic silvery, shiny appearance, they are electrically conductive, flexible (except for mercury which is liquid), and they engage in chemical reactions in which they are electron donors, forming positive ions. Non-metals are less shiny, generally not good electrical conductors, not as flexible, and they engage in chemical reactions in which they receive electrons, forming negative ions. Some non-metals such as carbon can either give or receive electrons, but even when they give electrons they do not do so as readily as metals do.

Basically the nonmetals. Many of them receive electrons, like oxygen, nitrogen, selenium, tellurium, and many others.
An atom with more electrons than protons is usually found in a chemical bond. They are called "anions", or negatively charged ions. (An ion is any atom that is either positively charged or negatively charged.) They are negatively charged because electrons are negatively charged.Anions are usually to always found in chemical bonds because all (stable, at least) elements are neutral, or have no charge. Why are they ever found in chemical bonds, you ask? Well, think about the Noble Gases, the group all the way on the right of the periodic table. The Noble Gases are completely inert, or they almost never react with anything. That all has to do with the amount of electrons they have. Essentially, all elements want to be like the Noble Gases. They share or lend electrons to other elements. To be more specific, metals give electrons and nonmetals receive electrons in chemical bonding. So, nonmetals receive more electrons than normal and they become like the Noble Gases, and that gives them a negative charge.
