Answer:
C.) 3 is the correct answer
1 pm = 10∧-10 cm
Therefore, 230 pm is equivalent to 2.3 ×10∧-8 cm.
Atom is in the shape of a sphere,
The volume of a sphere is given by 4/3πr³
Thus, volume of the atom = 4/3π( 2.3 ×10∧-8)³
= 4/3 (3.142 ×12.167×10∧-24
= 5.096 ×10∧-23 cm³
but 1m³= 1000000cm³
Therefore, the volume of the atom = 5.096 ×10∧-29 m³
Covalent Bond Name :N6Cl10
Explanation:
- Covalent compounds are named by using numerical prefixes to identify the number of atoms in the molecule. For example Carbon Dioxide CO2 and Carbon Monoxide CO . ... Drop the double vowel for the prefix and the element of the second element in the compound.
- The three types as mentioned in the other answers are polar covalent, nonpolar covalent, and coordinate covalent. The first, polar covalent, is formed between two nonmetals that have a difference in electronegativity. They share their electron density unevenly.
- Examples of Covalent Bond: Water. An example is water. Water consists of a covalent bond containing hydrogen and oxygen bonding together to make H2O. ...Diamonds. A diamond is an example of Giant Covalent bond of carbon. A diamond has a giant molecular structure. ...Vulcanized rubber. Another example is vulcanized rubber.
- Covalent bonds are especially important since most carbon molecules interact primarily through covalent bonding. Covalent bonding allows molecules to share electrons with other molecules, creating long chains of compounds and allowing more complexity in life.
Diamond and graphite are made of carbon. So is most of charcoal.
