metallic character decreases, and electronegativity increases
What else can I help you with?
Where do elements that are good insulators appear on the periodic table?
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.
What are the two elements in the same period as magnesium?
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.
Are period 1 elements more electronegative than period 2 elements?
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.
What are the characteristics of a period in the periodic table?
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.
Does the electronegativity of the elements on the right side of the same period tend to be higher?
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.
Where do elements that are good insulators appear on the periodic table?

What is a set of elements that runs from left to right?
period
Where the elements in period 3 of the periodic table are considered from left to right the degree of nonmetalic character of each successive element tends to do what?
The nonmetallic character begin with silicon and increase to right.
What are the two elements in the same period as magnesium?
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.
How does the electronegativity of elements change across a period?
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.
Are period 1 elements more electronegative than period 2 elements?
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.
Compared with electronegativities of the elements on the left side of a period the electronegativities of the elements on the right side of the same period ten to be?
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.
What element in period 3 is metallic?
In period three, all elements but the four on the right are metallic.
Which characteristics both generally decrease When the elements in period 3 on the periodic table are considered it order from left to right?
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.
What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
The row of elements going left to right on the periodic table is called?
This row of chemical elements is a "period".
What is the term for a row of elements going from left to right on the periodic table?
Period
