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 is the row across the periodic table called?
Period
What is the horizontal row across the periodic table?
A horizontal row on the periodic table of elements is called a period.
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 decreases across the periodic table?
Atomic size decreases across a period
When does the radius of an atom decreases or increases?
The radius of an atom typically decreases when moving from left to right across a period in the periodic table due to increasing nuclear charge. It increases when moving down a group in the periodic table due to the addition of energy levels.
An elements blank is its row in the periodic table?
The periodic table is an arrangement of the elementsfound in nature.
What number is copper in the periodic table?
period 4, 11 across
What stays the same across a period on the periodic table?
the atomic number.
What is the definition of horizontal rows on periodic table?
Horizontal rows on the periodic table are called periods. Each period represents the number of energy levels or electron shells that an atom's valence electrons occupy. Moving from left to right across a period, the number of protons and electrons increases.
How does reading across a period the periodic table compare with reading down a group of the table?
Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.
