What does mendeleevs first periodic table look like?
The first periodic table was a handwritten table by Mendeleev. It had groups horizontally across the top and periods down the left hand side. The elements were all put into certain groups with only their chemicals symbols and atomic numbers depicted.
Across the periodic table the properties of elements become WHAT?
across a periodic table, the properties of elements become less metallic and more nonmetallic
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 is the horizontal row across the periodic table?
A horizontal row on the periodic table of elements is called a period.
Do the elements to the right of the periodic table have small or large radii?
Across a period the atomic size decreases. Hence elements in the right side of the periodic table have small size / radii.

A row of elements across the periodic table is an?
The rows across the periodic table are called periods.
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.
Properties of elements change according to a pattern across the?
Groups of the Periodic Table of Elements.
O The periodic table of elements is the arrangement of elements according to?
The periodic table of elements is the arrangement of elements according to atomic number increasing from left to right across rows of the table.
How does electronegative vary across a periodic?
The electro-negativity of elements increases as you move across a period.
What is the horizontal row across the periodic table?
A horizontal row on the periodic table of elements is called a period.
How do elements changes as you across the periodic table?
the number of protons increases
Do the elements to the right of the periodic table have small or large radii?
Across a period the atomic size decreases. Hence elements in the right side of the periodic table have small size / radii.
What are the names of the periods on the periodic table?
Periods are the elements on the periodic table that go across, in rows. So basically going across each row is called a period
What is a row of elements across the periodic table called?
The rows going across the periodic table are called periods. As you go across a row, each element increases in number of protons and electrons, which distinguishes it from other elements in the table.
