The combination of a nonmetal atom with a metal atom is perhaps the most common chemical reaction that we are familiar with. Take, for instance, the classic example of sodium chloride (NaCl) which is table salt.
In sodium chloride, the sodium metal reacts with chlorine gas to form a compound. The compound formed is an ionic compound. It is ionic in nature because the metal atom, sodium, has a natural tendency to lose electrons. The chlorine gas, on the other hand has a natural tendency to gain electrons. The purpose of gaining and losing electrons by atoms is to achieve a stable electron configuration that matched that of the noble (inert) gases. The noble gases, which include helium, argon, krypton, neon, xenon, and radon have one thing in common that distinguishes them from other types of elements. Their outer most shell which contains valence electrons is completely filled. In other words.
Relating to the idea of a stable shell, sodium, which has one electron in its valence shell, could achieve this stable configuration by losing one electron.
Chlorine, on the other hand, has seven valence electrons in its outermost shell. Since it needs only one electron to achieve the stable configuration of eight electrons, chlorine accepts one electron from sodium.
The reason why sodium chloride and other reactions between alkali metals and chloride are used as the classic examples of a chemical reaction between metals and nonmetals is because they involve the lose of one electron and the acceptance of one electron. Chemical reactions between metals and nonmetals become more complex as metals that lose more than one electron are involved. For example, the reaction between magnesium and chloride involves the lose of two electrons by magnesium to a chlorine atom. Because a chlorine atom needs one electron to achieve a stable electron configuration, accepting two electrons would be not practical. Therefore, for each magnesium atom that loses two electrons, two chlorine atoms gain electrons.
The following is an illustration of the reaction that takes place between magnesium and chlorine:
Mg(s) + Cl2(g) --> MgCl2
Overall, any reaction that occurs between a nonmetal and metal involves a transfer of electrons from the metal to the nonmetal.
Molecules can be made up of both metal and non-metal atoms, depending on the type of compound. For example, ionic compounds such as sodium chloride (NaCl) consist of a metal atom (sodium) and a non-metal atom (chlorine), while covalent compounds like water (H2O) can consist of non-metal atoms only.
Yes
In Cu2O, there are 2 copper atoms, which are metals, and 1 oxygen atom, which is a non-metal. So, there is 1 non-metal atom (oxygen) in Cu2O.
Hydrogen fluoride (HF) is a compound composed of hydrogen and fluorine atoms. Fluorine is a non-metal, while hydrogen is a non-metal as well. Therefore, HF is considered a covalent compound rather than a metal or non-metal.
Covalent bonds typically form between non-metal atoms, such as hydrogen, carbon, nitrogen, oxygen, and fluorine. These atoms share electron pairs to achieve a full outer electron shell and achieve stability.
generally anions are formed
electrons are transferred from the metal atoms to the non-metal atoms forming ions resulting in an ionic compound
metal
Covalent bonds may contain two non metal atoms. Example is CH4.
it depends on the valency of the atoms
yes both the carbon and oxygen are non metal atoms but beside this carbodioxide is lethal

A metal and a non-metal
In Cu2O, there are 2 copper atoms, which are metals, and 1 oxygen atom, which is a non-metal. So, there is 1 non-metal atom (oxygen) in Cu2O.
Atoms of non-metals usually gain or share electrons when they react with other atoms.
Ionic bonds refer to the attraction between metal ions and non-metal ions due to the electrostatic attraction.It is formed by the electron transfer between the metal atoms and the non-metal atoms. It is non-directional and electrically neutral. Electrolysis can be used to separate the ions into their original atoms. p.s. metals always form cations and non-metal always form anions.
