Answer:
D
Explanation:
The SI unit for density is the kilogram per cubic meter (kg/m3 ).
Answer:
Subtract the charge from the atomic number. When an ion has a positive charge, the atom has lost electrons. To calculate the remaining number of electrons, you subtract the amount of extra charge from the atomic number. In the case of a positive ion, there are more protons than electrons.
Explanation:
Number of electron pairs = \frac{1}{2}[V+N-C+A]
2
1
[V+N−C+A]
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
SbCl_5SbCl
5
:
In the given molecule, antimony is the central atom and there are five chlorine as monovalent atoms.
The number of electron pairs are 5 that means the hybridization will be sp^3dsp
3
B and geometry of the molecule will be trigonal bipyramidal.
The particles of objects have
both kinetic and potential energy because these forces are drive by the force
of motion or stillness of an object. Potential energy is the a type of energy
which an object possess however without motion. Kinetic energy in the other
hand, is the energy in motion or if the object moves along from one space to
another with respect to time. They both have these two energies by the presence
of atoms in these entities.
