Explanation:
Most of the carbon compound are convalent in nature and all of the electrons participates in bond formation as such there is no free electrons left to conduct electricity. Moreover carbon compound doesn't readily dissociates to form ions, which conduct electricity. Hence carbon compound are poor conductor of electricity.
Answer:
It is because all the valence electrons are used to form covalent bonds. So, there will be no electrons left to flow the electric current through them.

This hypothetical process would produce actinium-230.
An alpha decay reduces the atomic number of a nucleus by two and its mass number by four.
There are two types of beta decay: beta minus β⁻ and beta plus β⁺.
The mass number of a nucleus stays the same in either process. In β⁻ decay, the atomic number increases by one. An electron e⁻ is produced. In β⁺ decay, the atomic number decreases by one. A positron e⁺ is produced. Positrons are antiparticles of electrons.
β⁻ are more common than β⁺ in decays involving uranium. Assuming that the "beta decay" here refers to β⁻ decay.
Gamma decays do not influence the atomic or mass number of a nucleus.
Uranium has an atomic number of 92. 238 is the mass number of this particular isotope. The hypothetical product would have an atomic number of 92 - 2 ⨯ 2 + 1 = 89. Actinium has atomic number 89. As a result, the product is an isotope of actinium. The mass number of this hypothetical isotope would be 238 - 2 ⨯ 4 = 230. Therefore, actinium-230 is produced.
The overall nuclear reaction would involve five different particles. On the reactant side, there is
On the product side, there are
Consider: what would be the products if the nucleus undergoes a β⁺ decay instead?
Metallic Bond is basically a electrostatic force of attraction between the metal ions which are arranged in a lattice(Lattice is a regular repeating pattern) and the free electrons floating around the metal ions.
1- Metals are good conductors of heat and electricity
2- Metals are ductile
3- Metals are malleable
4- Metals are solid at room temperature
5- Metals Possess Metallic luster
Elements which are arranged in increasing order of atomic radii are F,Cl,Br, I.
Atomic radius is defined as the distance between nucleus of an atom and the valence electrons.In a group, atomic radii increases up to down as electrons are added in the next successive shell which increases the size of atom.
In a period, as electrons are added to the same shell the force of attraction between nucleus and valence electrons increases as a result of which atom tend to shrink resulting in decrease in atomic size.
As fluorine, chlorine, bromine and iodine are present in the same group their atomic size increases as new shells are added from top to bottom of periodic table., while for the elements given in other options they are present in same period or in different group and hence do not show an gradual increase in atomic radii.
