Carbon is the most electronegative ion of his group in the periodic table. That`s why carbon alone forms negative ions, in the form of carbide ions. Even though silicon can form silicides, but they are structurally closer to borides than to carbides, because silicon is more electropositive. Also the chemical bonds in silicides range from conductive metal-like structures to covalent or ionic. Other elements of the fourth group are more electropositive and can’t form negatively charged ions.

Element x is found in group 2A and element Y in group 5A how many electrons are transferred when these elements form a compound

No electrons are transferred since both elements need to gain 2 valence electrons to attain octate state so the two elements will share the outer electrons in their outer ring....

a) Find the electronic configuration of Mo. b) For transition elements, why does the ionization enthalpy tend to increase along the series only slightly as compared to the main group elements?

a) electronic configuration of Mo1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d5 5s1b) The ionization energy increases due to the increase in the nuclear charge with an atomic number at the beginning of the series. Gradually, the shielding effect of the added electrons...

why d-block elements elements are called as outer transition elements and f-block elements as inner transition elements?

The d-block elements are called transition metals and have valence electrons in d orbitals. The inner transition elements are those who have their last 3 shells incompletely filled. The f...

Carbon can form acetylides and methanides, while the other elements in the group are unable to do so.

Acetylides contain the polyatomic ion C22−, in which there is a triple bond between the two carbon atoms (similar to acetylene). Examples are carbides of the alkali metals (such as...

Atomic and ionic radii of the elements of group 16 are smaller than those of the corresponding elements of group 15 and increases down the group. Why?

The atomic radius of group-16 elements or oxygen family are smaller than that of group-15 elements. This is due to increase in the effective nuclear charge from group-15 elements which...

Identify the type of hybridization of the carbon atoms in the following compound: CH 2 = CHCOCH 3 Also predict the carbon-carbon and carbon-hydrogen bond length using Table 4.4.

The carbons of CH2=CH and CO have sp2-hybridization. The carbons of CH3 have sp3-hybridization. The distances of C(sp3)-C(sp3) bonds are around of 154 pm. The distances of C(sp3)-C(sp2) bonds are...

how do the first ionization energies for the group B elements compare to each other? to the group A elements?

The more electrons protect the outer electron shell from the nucleus, the less energy is required to extract the electron from the specified atom. The higher the protective effect, the...

Four moles of carbon monoxide (CO) has 48 grams of carbon (C) and 64 grams of oxygen (O). What is the percent composition of carbon in carbon monoxide?

Answer: m (CO) = n*M, where n is the amount of substance, mole, M is the molar mass, g/mole m (CO) = 4*28 = 112 g % C = m...
