why iron are not formed by carbon? Describe the natural bonds formed by carbon why is bond are weak
Answers
Answer:
Carbon has 6 electrons, two in its inner shell and four in its valence shell. When carbon takes four electrons from other atoms, in which it forms ionic bonds, it has a full valence shell, so it is unable to from any more bonds
Explanation:
types of
Summary
Carbon forms covalent bonds with atoms of carbon or other elements. ...
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. ...
Carbon can form single, double, or triple covalent bonds with other carbon atoms.

Answer:
Octet rule - Matter always wants to be in the most stable form. For any atom, stability is achieved by following the octet rule, which is to say all atoms (with a few exceptions) want 8 electrons in their outermost electron shell (just like noble gases). The electrons present in the outermost shell of an atom are called valence electrons.
Exceptions to the octet rule include hydrogen (H) and helium (He) that follow the duet rule instead. They are the first two elements of the periodic table and have a single electron shell which accommodates only 2 electrons. Other exceptions include some group 3 elements like boron (B) that contain three valence electrons. Theoretically, boron can accommodate five more electrons according to the octet rule, but boron is a very small atom and five non-metal atoms (like hydrogen) cannot pack around the boron nucleus. Thus, boron commonly forms three bonds.
