How was mendeleevs periodic table like todays periodic table?
Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
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.
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.
Across the periodic table the properties of elements become WHAT?
Across the periodic table, the properties of elements become more predictable and show periodicity, meaning they exhibit regular patterns in their physical and chemical properties. This is due to the arrangement of electrons in the atom and the increasing number of protons in the nucleus as you move from left to right across the table.

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 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.
Why do youthink the elements are arrange the way that they are?
On the Periodic Table of Elements, the order from top left to bottom right is determined by the atomic number of that element, which is determined by the number of protons that are present in the nucleus of that element's atom.
What information about elements can be obtained from this organizing tool?
information about elements can be obtained from this organizing tool
What is the horizontal row across the periodic table?
A horizontal row on the periodic table of elements is called a period.
How does electronegative vary across a periodic?
The electro-negativity of elements increases as you move across a period.
How do elements changes as you across the periodic table?
the number of protons increases
A chart that arranges all known elements into groups?
Is the Periodic Table. The columns down are the GROUPS The lines across are the PERIODS.
Across the periodic table the properties of elements become WHAT?
Across the periodic table, the properties of elements become more predictable and show periodicity, meaning they exhibit regular patterns in their physical and chemical properties. This is due to the arrangement of electrons in the atom and the increasing number of protons in the nucleus as you move from left to right across the table.
