The atomic radius decreases from left to right and increases from top to bottom
The atomic number increases in the periodic table. The atomic number represents the number of protons in the nucleus of an atom, and it increases by one as you move from left to right across a period on the periodic table.
When moving left to right across a period on the periodic table, the number of valence electrons increases by one with each element. This is because the atomic number increases, resulting in a higher number of electrons in the outermost shell (valence shell).
As a general rule, when moving left to right on the periodic table the atomic radius decreases due to increasing electromagnetic attraction of the nucleus to the electrons.
It decreases across a period. Since the atomic number increases, so does no. of protons and electrons. This makes the electrostatic force of attraction between electrons larger and hence the atom shrinks a bit. This makes the radius smaller.
The atomic radius decreases from left to right across a period in the periodic table. This is due to the increasing number of protons in the nucleus, which pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
The atomic number increases
Atomic radii decreases on moving from left to right as the effective nuclear charge increases.
moving from left to right across a period, one electron is added for each element.example: Boron has 3, Carbon has 4.
The atomic number increases in the periodic table. The atomic number represents the number of protons in the nucleus of an atom, and it increases by one as you move from left to right across a period on the periodic table.
Atomic radius increases down a group. Metallic character also increases down the group.
Atomic radii increases moving down a group in the Periodic Table due to the increasing energy levels in the electron configuration and electrons filling in energy levels further away from the nucleus.
When moving left to right across a period on the periodic table, the number of valence electrons increases by one with each element. This is because the atomic number increases, resulting in a higher number of electrons in the outermost shell (valence shell).
As a general rule, when moving left to right on the periodic table the atomic radius decreases due to increasing electromagnetic attraction of the nucleus to the electrons.
From left to right , atomic number increases. Number of neutrons also increases.
It decreases across a period. Since the atomic number increases, so does no. of protons and electrons. This makes the electrostatic force of attraction between electrons larger and hence the atom shrinks a bit. This makes the radius smaller.
The atomic radius decreases from left to right across a period in the periodic table. This is due to the increasing number of protons in the nucleus, which pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
Moving across a period from left to right, the atomic number of the elements increases. This results in an increase in the number of protons and electrons, leading to a greater nuclear charge. As a result, the size of the atoms decreases while the electronegativity and ionization energy increase.
