metallic character decreases, and electronegativity increases
Generally elements with modest electrical conductivity are at the right of the Periodic Table of Mendeleev: groups 14-18. But they cannot be considered as insulators.
Magnesium is in period 3 of the periodic table. The two elements in the same period as magnesium are aluminum (Al) and silicon (Si). Both elements follow magnesium in this period, with aluminum located to the right of magnesium and silicon further to the right.
No, period 1 elements are not more electronegative than period 2 elements. Electronegativity generally increases across a period from left to right, so elements in period 2 are generally more electronegative than elements in period 1.
Elements in a period all have the same number of electron shells (excepting the transition elements). Also, electronegativity increases left to right and up, and atomic radii increase right to left and down.
Yes, generally the electronegativity of elements increases as you move from left to right across a period on the periodic table. This trend is due to the increased nuclear charge and decreased atomic size as you move across the period, which results in stronger attraction for electrons.

period
The nonmetallic character begin with silicon and increase to right.
Magnesium is in period 3 of the periodic table. The two elements in the same period as magnesium are aluminum (Al) and silicon (Si). Both elements follow magnesium in this period, with aluminum located to the right of magnesium and silicon further to the right.
The electronegativity of elements generally increases across a period from left to right. This means that elements on the right side of the periodic table tend to attract electrons more strongly than elements on the left side.
No, period 1 elements are not more electronegative than period 2 elements. Electronegativity generally increases across a period from left to right, so elements in period 2 are generally more electronegative than elements in period 1.
lower. Electronegativity generally decreases as you move from left to right across a period on the periodic table since the elements on the right side have fewer valence electrons and thus lower electronegativities.
In period three, all elements but the four on the right are metallic.
As you move from left to right across period 3 on the periodic table, the atomic radius, metallic character, and reactivity generally decrease. This is because the increasing number of protons in the nucleus leads to stronger attraction for the electrons, resulting in a smaller atomic size and less metallic behavior.
The trend in period 2 ionization energy across the elements increases from left to right.
