What trend can be identified on the periodic table?
One trend that can be identified on the periodic table is the periodicity of elements, which refers to the repeating patterns of properties such as atomic number, atomic mass, and chemical reactivity across rows and columns.
What are the sources of polarizability?
The sources of polarizability include the electronic cloud of an atom or molecule, which can be distorted by an external electric field, causing polarization. This distortion leads to the formation of temporary dipoles, inducing a dipole moment in the atom or molecule. Additionally, the structure and symmetry of the atom or molecule also play a role in determining its polarizability.
What is the relationship between dipole moment and polarizability in molecules?
The dipole moment of a molecule is related to its polarizability. A molecule with a higher dipole moment tends to have higher polarizability, meaning it can be easily distorted by an external electric field. This is because the distribution of charge within the molecule is more uneven in molecules with higher dipole moments.
What is the Group trend Atomic radius?
The group trend for atomic radius is that it tends to increase down a group in the periodic table. This is because as you move down a group, the number of electron shells increases, leading to a larger atomic radius. Additionally, the effective nuclear charge decreases down a group, which also contributes to the increase in atomic radius.
What is the relationship between polarity and polarizability in chemical compounds?
Polarity in chemical compounds refers to the distribution of charge within the molecule, while polarizability is the ability of a molecule to be distorted by an external electric field. Generally, compounds with higher polarity tend to have higher polarizability because the distribution of charge allows for easier distortion of the electron cloud.
What is SI unit of atomic polarizability?
The SI unit of atomic polarizability is cubic metre or m^3.
When the electron cloud of a molecule is easily distorted the molecule has a high?
Polarizability
How do you find Polarizability?
Polarizability is a measure of how easily the electron cloud of an atom or molecule can be distorted by an external electric field. It can be experimentally determined by measuring the relative change in polarizability when subjected to an external electric field. Quantum mechanical calculations can also be used to predict polarizability based on the electronic structure of the system.
What do you predict the trend in atomic mass will be going down a group?
The atomic mass increases down a group.
What is the general trend that you observe from a graph that plots atomic number vs atomic mass?
The general trend observed is that as atomic number increases, atomic mass also increases. This relationship is due to the fact that atomic number corresponds to the number of protons in an atom's nucleus, which in turn contributes to its mass.
What is the exception to the atomic mass trend in period 4?
The exception to the atomic mass trend in period 4 of the periodic table is the reversal in atomic masses between argon (Ar) and potassium (K). Potassium has a higher atomic mass than argon, which is contrary to the trend of increasing atomic mass from left to right seen in the other elements of period 4.
What is the trend for atomic mass?
It increases as you move to the right or go down
What is the trend from left to right for atomic mass on the periodic table?
The atomic weight (not mass) increase from left to right in a period.
What trend can be identified on the periodic table?
One trend that can be identified on the periodic table is the periodicity of elements, which refers to the repeating patterns of properties such as atomic number, atomic mass, and chemical reactivity across rows and columns.
What trend do you note for the atomic radii of period 3?
The size of atom decreasing.
Is the pattern of atomic radius absolute or general?
The pattern is a general trend that is very consistant
Do transition elements follow the same trend of atomic radius as the main group elements?
NO
