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 is the ionic radius trend across a period?
Atoms increase in size as you go down a column and are larger going from right to left across a row.because while going from left to right in a period electrons enter in the same orbit and hence the attraction between the nucleus increasees
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.
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
How does the atomic mass size change as you move down the periodic table?
Atoms increase in size as you go down a column and are larger going from right to left across a row.because while going from left to right in a period electrons enter in the same orbit and hence the attraction between the nucleus increases ,,
How does the atomic number change in a period?
When going left to right across a period, the atomic number of element increases.

What general trend in electronegativity do you note going down a group across a period?
going down a group, electronegativity decreases going across a period, electronegativity increases
What trend can be observed among the atomic radii of main-group elements down a group?
Within a group, the number of shells (or energy level) increases (as we go from top to bottom of a group) and hence the size of the atom or the atomic radii increases.
What is true about the properties of the elements in any one period of the Periodic Table?
All of the elements in any one period of the Periodic Table have the same number of valence electrons.
Why does atomic radii decrease moving left to right across a period?
From going left to right on a period, the electrons are filled in the same shell. The atomic number increases, hence the number of protons in the nucleus increases. The effective nuclear charge thus increases. As a result the nucleus exerts more attraction on the valence electrons and hence the size / radius decreases.
How IS The electronegativity trend relates to the first ionization energy trend?
Electronegativity and first ionization energy both increase going up the Periodic Table.
How does the first ionization energy change going down and across the periodic table?
In a group the first ionization energy decrease going down.In a period the first ionization energy increase from left to right.
