Each hydrogen atom has one electron and needs two to complete its first energy level. Since both hydrogen atoms are identical, neither atom will be able to dominate in the control of the electrons. The electrons are therefore shared equally.
Why do carbon atoms share electrons?
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.
Why are electrons not shared equally between hydrogen and oxygen?
The bonds between oxygen and the hydrogen atoms within the water molecule are polar covalent bonds,i.e., the electrons are not shared equally between oxygen and hydrogen. … Because the molecule exhibits polarity, water molecules are attracted to each other (opposite charges attract).
Why is carbon a unique element?
Carbon atoms are unique because they can bond together to form very long, durable chains that can have branches or rings of various sizes and often contain thousands of carbon atoms. … Carbon atoms also bond strongly to other elements, such as hydrogen, oxygen, and nitrogen, and can be arranged in many different ways.
Why carbon is the element of life?
Why is carbon so basic to life? The reason is carbon’s ability to form stable bonds with many elements, including itself. This property allows carbon to form a huge variety of very large and complex molecules. In fact, there are nearly 10 million carbon-based compounds in living things!
Is hydrogen negative or positive?
Hydrogen is a positive ion. Hydrogen atoms consist of a proton in the nucleus surrounded by one electron.
Are electrons in water shared equally?
Electrons shared between unlike atoms are not shared equally, one atom gets more of the common electrons and is thus slightly negatively charged. The other atoms gets less than a full share of the electrons and is thus slightly positively charged.
Why are 4 bonds not possible?
There is no 4 bond formed between carbon because of the carbon electron orbitals. … Since it has 4 valence electrons, it needs 4 more to electrons to fill its outer energy level. It does so by forming covalent bonds with another element, in order to complete its Octet rule.
Can carbon have more than 4 bonds?
According to organic chemistry 101, carbon can form up to four bonds because it only has four shareable electrons. … According to their calculations, the exotic molecule would rearrange itself into a configuration where one carbon atom was bonded to six other carbons.
