Why do the numbers Increase as you go from left to right on the Period Table?

The numbers are just a label. Column 1 through column 18. There are a variety of patterns to notice as you move left to right. The most important would be that as you move to the next column you add one more proton. If you're speaking of neutral atoms, you add one electron.

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 are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
What happends to the valence electrons is they are moved from left to right in the periodic table?
Valence electrons increase in number on moving from left to right on the periodic table. another question might be
What is the atomic number and its trend on the periodic table?
The atomic number of an element is the number of protons in the nucleus of one atom of that element. In general, atomic numbers increase as you move to the right and down in the table.

First ionization energy increase
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.
How do atomic numbers and atomic masses increase in the periodic table?
The atomic number and atomic masses increase as you move from left to right.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What happens to reactivity of elements in groups labeled a as atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
Does electronegativity increases or decreases as you move left to right across a period on the periodic table?
Electronegativity increases to the right across a period and up a group.
How does electronegativity increase or decrease in modern periodic table?
Electronegativity increases from left to right across a period and decreases down a group.
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
they become more reactive since you are moving from left to right on the periodic table, the elements in group 17 are the most reactive.
How do protons increase on the periodic table?
they increase left to right
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
What is the trend ionization energy?
From left to right on the periodic table, ionization energy increases. From top to bottom in a column (group) the ionization energy decreases.
What is the atomic number and its trend on the periodic table?
The atomic number of an element is the number of protons in the nucleus of one atom of that element. In general, atomic numbers increase as you move to the right and down in the table.
