Answer:
Oxygen is the oxidizing agent and accept electrons
Explanation:
two metal anions
a metal cation and a nonmetal anion
two nonmetal cations
ionic compounds are held together by ionic bonds are formed by the transfer of electrons from a metal to a non metal
Ionic bond is formed by the electrostatic attraction between the oppositely charged ions.
metals give out electrons and becomes positively charged. positively charged ions are called cations. so these are called metal cations
the electrons given out are taken in by non metals and become negatively charged. negatively charged ions are called anions. then they are called non metal anions.
so ionic compounds are formed by the electrostatic attraction between metal cations and non metal anions.
therefore ionic compounds are composed of a metal cation and a nonmetal anion
the basic unit of life is the cell
all cells have the same basic structure
cells are miniature reflections of the organisms from which they are taken
Answer:
the basic unit of life is the cell
The covalent bonds present in based on the valence electrons and thus form 4 bonds.
The valence electrons are the number of electrons present on the last orbital of the atom.
The atomic number of carbon is 6, thereby it is given with the electronic configuration 2, 4.
There is the presence of the 4 valence electrons in the carbon atom, and thereby the number of covalent bonds formed by carbon atom is 4.
