1.)Boron
2.)Cadmium has 48 electrons not 121 Mercury has 80 And Copernicum so they all have no 121 electrons
3.)Hydrogen
Answer: The positive and negative charges of the water molecule pull on the negative and positive ends of the ionic molecule to break them apart.
Explanation:
Ionic compounds dissolve in polar solvents such as water as like dissolves like. Ionic compounds are made up of ions which remain attracted by coloumbic forces.
Thus to separate the ions, the positive and negative charges of polar solvent pulls the opposite charges of the ionic compounds and thus break them apart. Thus the ionic compounds dissolve in water.
Answer : The hybridization of the positively charged carbon is .
Explanation : Formula used for Hybridization
Z=1/2{number of valence electrons of central atom + number of monovalent atom attached to it + negative charge - positive charge}
where, Z = Hybridization
Now for the compound
Number of valence electrons of central atom (C) = 4
Number of monovalent atom attached = 3
Number of negative charge = 0
Number of positive charge = 1
Now putting all the values in Z,
Z =
= 3
The corresponding Hybridization is i.e Trigonal planar .
