The figure shows the hybrid orbitals of methane. mc022-1.jpg which molecule has the same shape and hybridization as methane? so3 c2h2 ch2o cf2cl2

In methane the central C atom is bonded to 4 H atoms forming 4 covalent bonds and adopts a tetrahedral geometry.

The valence electron configuration of C = 2s²2p²

H = 1s¹

In methane, one electron from the 2s orbital of C gets promoted to the 2p orbital creating 4 unpaired electrons. This mixing of the 2s-2p creates 4 sp3 hybrid orbitals each of which then bonds to the 1s orbital of H. Thus, in CH3, the C atom is sp3 hybridized.

This pattern of hybridization is also exhibited by CF2Cl2 in which the central C atom is spe3 hybridized and forms 4 covalent bonds: 2 C-F and 2 C-Cl

Ans: D) CF2Cl2

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
