Two things happen when you move from right to left. First, the number of valence electrons increases from one to eight. Secondly, the number of protons increases from three to ten. There is also the transition from alkali metal to alkaline earth metal to metalloid to nonmetal to halogen to noble gas.
What else can I help you with?
Do the size of cations increase or decrease?
Cations generally decrease in size as you move from left to right across the periodic table due to increasing nuclear charge pulling the electrons closer to the nucleus. However, cations increase in size as you move down a group due to the addition of electron shells.
When does the radius of an atom decreases or increases?
The radius of an atom typically decreases when moving from left to right across a period in the periodic table due to increasing nuclear charge. It increases when moving down a group in the periodic table due to the addition of energy levels.
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
Moving across a period on the periodic table from left to right?
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.
Does nuclear charge increases as you move from left to right across the periodic table?
moving from left to right across a period, one electron is added for each element.example: Boron has 3, Carbon has 4.

How does cation vary across a row and down a column of the periodic table?
According to the modern Periodic Law, atomic number affects the physical and chemical properties of an element, so the elements are arranged in an ascending order according to their atomic number...therefore, it increases by one across a row of the periodic table.
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
What sub atomic particle increases as you move to the right across the periodic table?
Electronegativity increases as you move across the periodic table from left to right.
What sub atomic particle increasesas you move to the right across the periodic table?
Electronegativity increases as you move across the periodic table from left to right.
How do atomic radii change from left to right across a horizontal row of the periodic table and what is the main reason?
Atomic radii decreases on moving from left to right as the effective nuclear charge increases.
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
Moving across a period on the periodic table from left to right?
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.
Does nuclear charge increases as you move from left to right across the periodic table?
moving from left to right across a period, one electron is added for each element.example: Boron has 3, Carbon has 4.
Which direction do electronegativity increases?
The electronegativity increases as you move bottom to top, and left to right on the periodic table. Why? Because you are moving towards Fluorine, which is the most electronegative element.
What goes across the periodic table?
The periodic table is arranged by increasing atomic number, which moves from left to right across each row. As you move from left to right across a row, the elements increase in atomic number and atomic mass, with similar chemical properties grouped together.
