Electronegativity increases across the second and third periods or rows of the Periodic Table until the noble gases are reached; then electronegativity drops substantially. There is little change if any in electronegativity in the part of the higher numbered periods that represents transition metals, but the increase in electronegativity resumes in column 13 of these periods.
What else can I help you with?
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
What happens to conductivity when moving across periodic table?
metal--> nonmetal --> metalloid
What happens to the properties of elements across any periodic of the table?
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
What happens to the melting temperature as you go from left to right across a row in the periodic table?
it increases then decreases
A row across the periodic table is called a?
groupsi
A row of elements across the periodic table is an?
A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
What happens to the atomic number as you go from left to right across the periodic table and why does this happen?
The atomic number increases from left to right across the periodic table because the number of protons in the nucleus of an atom increases. This results in a higher positive charge, leading to a stronger attraction to electrons and a closer binding of electrons to the nucleus.
Why don't atoms simply get larger you read across the periodic table?
because the no. of shells in the atoms across the Periodic Table remains the same
What is the horizontal row across the periodic table?
A horizontal row on the periodic table of elements is called a period.
What sub atomic particle increases as you move to the right across the periodic table?
Electronegativity increases as you move across the periodic table from left to right.
What sub atomic particle increasesas you move to the right across the periodic table?
Electronegativity increases as you move across the periodic table from left to right.
What happens to the state of matters you go across the periodic table?
Across the period (left to right), the elements tend to change from solids (metals) to gases (non metals).
