What increases in the periodic table?
As you move from left to right across a period in the periodic table, the atomic number increases. This increase in atomic number corresponds to an increase in the number of protons in the nucleus of the atom.
From left to right across the second period of the periodic table?
The second period of the periodic table contains elements from lithium to neon, in increasing atomic number order. These elements have increasing numbers of protons and electrons as you move from left to right across the period, resulting in changes in properties such as atomic size and reactivity.
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 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.
How do atomic numbers and atomic masses increase in the periodic table?
Atomic numbers increase from left to right across a period on the periodic table. This is because each element in a period has one more proton in its nucleus compared to the element before it. Atomic masses generally increase from left to right as well, but there may be deviations due to isotopes or other factors. Within a group or column, atomic numbers and atomic masses increase from top to bottom as each successive element has more electrons and neutrons than the one above it.
What is the general trend in densities for period 2?
The general trend in densities for period 2 elements of the periodic table is that densities increase from left to right. This is because elements in period 2 have increasing atomic numbers, leading to an increase in atomic mass and a decrease in atomic volume, resulting in higher densities.
What increases in the periodic table?
As you move from left to right across a period in the periodic table, the atomic number increases. This increase in atomic number corresponds to an increase in the number of protons in the nucleus of the atom.

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 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.
How do protons increase on the periodic table?
they increase left to right
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
In a group labeled as A, as atomic numbers increase across a period, the reactivity of elements generally decreases. This is because as you move from left to right across a period, the elements have more protons in the nucleus, which leads to stronger nuclear charge and less tendency to lose electrons and react with other elements.
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.
An increase in the atomic number the atomic radius moving from left to right across a period.?
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.
