Does atomic density increase or decrease as we go across in a period?
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.
How much does the atomic number increase bye as you go across a row on the periodic table?
Atomic number increases by one as we move from left to right in a periodic table.
What number increases in the periodic table?
Both the atomic number and atomic mass. among many other things. They increase the atomic number because the atomic number IS the number of protons in an atom. They increase the atomic mass because the atomic mass is the number of protons + neutrons in an atom. Basically the main two things..
What increases as you move up a column of the periodic table?
Electronegativity, ionization energy, electron affinity, and atomic number are values that increase from left to right across a period.
What accompanies an increase in atomic number within a specific period?
An increase in atomic number would be accompanied by a decrease in radius, and an increase in electronegativity.
What trends do you notice about the atomic number and atomic mass as you move left to right across the table?
they increase by one going from left to right totally a guess
When moving across a period in the periodic table?
The atomic number increases

Does the atomic number increase when moving left to rt on periodic table?
Yes.
How much does the number increase by as you go across a row on the periodic table?
The atomic number increases by 1 as one go across a row on periodic table. The elements are arranged in order of increasing atomic number.
What happens to the reactivity of elements in group a as atomic number increase across a period?
they do becaused they want to do it

What is the trend in atomic mass going down a group?
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
What happens to the atomic number as you go across a period?
The atomic number increases as one go across a period.
What increases as you move up a column of the periodic table?
Electronegativity, ionization energy, electron affinity, and atomic number are values that increase from left to right across a period.
What is the trend electronegative as atomic number increase across the period?
Electronegativity increases across a period. Element becomes more negatively charged.
