Does carbonate follow the octet rule?
The carbonate ion, or CO2−3 , has a total of 24 valence electrons, 4 from carbon, 6 from each of the three oxygen atoms, and 2 additional ones. The carbon atom obeys the octet rule because it has 8 electrons in its valence shell, 2 for each bond it has with the oxygen atoms.
What is charge on CO3?
Carbonate is made of 1 atom of carbon and 3 atoms of oxygen and has an electric charge of −2. This negative charge means that a single ion of carbonate has 2 more electrons than protons.
Why does CO3 have 24 electrons?
The Carbonate (CO2−3) Ion Carbon has 4 valence electrons, each oxygen has 6 valence electrons, and there are 2 more for the −2 charge. This gives 4 + (3 × 6) + 2 = 24 valence electrons.
Does no2 follow the octet rule?
Nitrogen dioxide is the chemical compound with the formula NO2. Again, nitrogen dioxide does not follow the octet rule for one of its atoms, namely nitrogen. The total number of valence electrons is 5+2(6)=17. There is persistent radical character on nitrogen because it has an unpaired electron.
Does CH4 violate the octet rule?
Yes for carbon atom in CH4 octet rule is satisfied. Carbon has four electrons in it’s valence shell. In CH4 carbon has one covalent bond with each of the 4 hydrogen atoms which share their electrons with the carbon atom .
What is CO3 used for?
Calcium carbonate decomposes to form carbon dioxide and lime, an important material in making steel, glass, and paper. Because of its antacid properties, calcium carbonate is used in industrial settings to neutralize acidic conditions in both soil and water.
Is CO32 polar or nonpolar?
CO32- or Carbonate is a polyatomic ion. It is made of three Oxygen atoms bonded with the Central Atom, which is Carbon. These bonded atoms are polar in nature, but CO32 is nonpolar.
Does CO32 have dative bond?
CO3 2- can then become monodentate by creating one coordinate bond using one oxygen atom’s lone pair, or become bidentate by creating two coordinate bonds using both the oxygen atoms with lone pairs. That O atom is already in a favorable state and would not likely want to form a coordinate bond.
Does h2so4 follow the octet rule?
No, Here the sulfur atom has six electron pairs in its valence shell. An atom like phosphorus or sulfur which has more than an octet is said to have expanded its valence shell.
Does CH4 obey the octet rule?
Which of the following elements obey octet rule?
Elements that obey octet rules are main group elements which are oxygen, carbon, nitrogen. s-block and p-block elements obey octet rule except for hydrogen, helium, and lithium. Octet Rule Examples. Few examples which follow octet rule are : CO 2, NaCl, MgO. 1.CO 2. Carbon contains four electrons in its outermost shell.
What is the octet rule in carbon dioxide?
The octet rule can be observed in the bonding between the carbon and oxygen atoms in a carbon dioxide molecule, as illustrated via a Lewis dot structure below. The shared electrons fulfil the valency requirements of both the bonded atoms.
Why is the duet rule used instead of the octet rule?
Since the first shell can only accommodate two electrons, elements such as lithium, helium, and hydrogen obey the duet rule instead of the octet rule. For example, lithium can lose an electron to have a stable configuration in which the valence shell holds two electrons.
Why does PCl5 violate the octet rule?
If all the phosphorus-chlorine bonds in a PCl 5 molecule are covalent, it would imply that the phosphorus molecule is violating the octet rule by holding a total of 10 valence electrons. The formation of five bonds by the phosphorus molecules can be explained by the sp 3 d hybridization in PCl 5.
