When two carbon atoms are linked by a triple bond, one will be a sigma bond (formed by the 2px-px overlap of the two carbon atoms) whereas the other two will be pi bonds (formed by the 2py-py overlap and 2pz-pz overlap of the two carbon atoms).
Carbon atoms form covalent bonds with other carbon atoms, and with other nonmetals, such as carbon and oxygen, or carbon and hydrogen.
It doesn't necessarily "bonds to four other atoms."
Carbon atoms are fixed into organic compounds in The Calvin Cycle.
A double carbon bond is a covalent bond. Also carbon atoms can form double bonds. Carbon shares electrons with other atoms.
Each carbon atom can covalently bond with as many as four other other atoms. Answer is 4.
Carbon atoms can bond to other carbon atoms in a variety of ways, but when they bond in a network, with all the atoms bonding to all the other atoms that surround them, it is a very strong bond, stronger than the bonds formed in other minerals. Strong bonds are, by definition, hard to break. Hence the material is very hard. Scratching it requires breaking bonds.
yes carbon is formed with other carbon atoms
yes
4. Carbon obeys the octet rule. In covalent conpounds it has 4 covalent bonds. It can also form ionic compounds (carbides).
celefidual bonds
carbon has 4 valence electrons and can form a maximum 4 bonds with other atoms.
