If a metal is bonded to carbon, they form ionic bonds. If a nonmetal forms a bond with carbon, they form covalent bond. Ionic bond requires metals to give away electrons to form cations and nonmetal to gain/accept electron to form anions. Covalent bond requires sharing of electrons between both elements. So if you meant exchange as in covalent bond, then no. Not many nonmetal elements form bonds with carbon as there are more metal elements in the periodic table.
A neutron is neutral and a proton is positive and a electron is negative
The given question is based on the concept of conversion factor
1 KL = 10³ L, 1cL = 10⁻³ L, 1dL = 10⁻² L, 1 nL = 10⁻⁹ L
<h3>What is Conversion factor ?</h3>
A conversion factor is an expression for the relationship between units that is used to change the units of a measured quantity without changing the value.
A conversion ratio (or unit factor) always equals one (1), where the numerator and the denominator have the same value expressed in different units.
Hence, The complete filled table is given as follows ;
1 KL = 10³ L,
1cL = 10⁻³ L,
1dL = 10⁻² L,
1 nL = 10⁻⁹ L
Where,
- KL is Kilolitre
- cL is centilitre
- dL is decilitre
- nL is nanolitre
