The compound 
is formed only by sharing of electrons between the atoms. The structure of the compound is shown in the image.
Each line between two atoms represents the sharing of an electron pair which results in the formation of a single bond. Since, carbon has 4 electrons in its valence shell and hydrogen has 1 electron in its valence shell so in order to complete the octet ( to have 8 electrons in their valence shell, noble gas configuration) to attain stability carbon needs 4 more electrons and hydrogen needs 1 electron. So, sharing of electron will occur as shown in the image and the formed compound is stable in nature.
Since, the bond that is formed by sharing of electrons between atoms is known as covalent bond. So, covalent bonding is most important in .
Answer:
Explanation:
Its simple
This is the number of atoms, ions, or molecules that a central atom or ion holds as its nearest neighbours in a complex or coordination compound or in a crystal.
for example: Sodium chloride (NaCl) or table salt is an ionic compound. It means that each cation will have exactly one anion associated with it, which means the cation Na+ and the anion Cl− have the same number of coordinates.
It may be really confusing at first
I recommend you go online and watch tutorial videos on the topic
Answer:
chemical means
Explanation:
Compounds can be separated by chemical means physical means boiling pressure
A chemical property would be its pH of 2.4.
all others are physical properties and aspect
hope that helps
You can use luminal to make it more visible. Trust me this is the answer because I had this question in my book. Hope it's useful.
