1) Elements on the modern Periodic Table are arranged in order of increasing:
(a) Atomic Mass
5 As the elements of Group 17 are considered in order of increasing atomic number, there is an increase in:
(1) Atomic radius
7) In the wave-mechanical model of the atom, orbitals are regions of the most probable locations of:
(4) electrons
2 Which phrase describes an atom?
(3) A negatively charged electron cloud surrounding a positively charged nucleus
3 Which total mass is the smallest?
(1) The mass of 2 electrons

How did mendeleev arrange his version of the periodic table?
Mendeleev arranged his version of the Periodic Table in terms of ascending atomic weights and similar properties. Since it was first published in 1869, there have been updates and improvements.
What elements did Dmitri mendeleev discover?
In 1869, a total of 63 elements had been discovered by. A few were gases. Two were liquids. Most were solid metals.
Why did Dmitri mendeleev reverse the order of some elements in the periodic table?
He was bold enough to reverse the order of some pairs of elements and to predict that their atomic masses were incorrect. Some of these predictions were correct, but others were not, because we now know that the fundamental basis of the periodic table is atomic number rather than atomic mass.
Dmitri Mendeleev was particularly important why?
He is important because he was the person who invented the Periodic Table and made it how it is today
What determines the order of the elements in the periodic table?
All elements in a column of the periodic table have the same number of valence electrons. Since their reactivity (i.e. its bonding) depends on the number of valence eletrons, elements in the same column should have similar chemical and physical properties.
What are some ways that elements are arranged on the periodic table of elements?
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
How are the elements on a Periodic Tables arranged?
The elements are arranged in the increasing order of their atomic number and repeating properties.
Are the elements on a periodic table arranged in order of decreasing atomic mass?
No. The elements are arranged in order of increasing atomic number.
Who developed periodic table?
Niels Bohr: the modern periodic table where the elements are arranged in the increasing order of atomic number Mendeleev: The periodic table where the elements are arranged in the increasing order of atomic mass
Mendeleev arranged the elements in his periodic table in order of?
Mendeleev arranged the elements in his periodic table in order of increasing atomic mass while also grouping elements with similar properties together. His periodic table laid the foundation for the modern periodic table we use today.
What is the modern periodic table is now arranged according to?
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
In the periodic table the elements are arranged in order of increasing?
In the periodic table, the elements are arranged in order of increasing atomic number from left to right and top to bottom. This arrangement allows elements with similar chemical properties to be grouped together in columns known as groups or families.
The periodic law states that the properties of elements will repeat when the elements are arranged by _______.?
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
What are the elements arranged in periodic table?
Around 118 elements are arranged in the increasing order of their atomic number and repeating properties.
How are elements are arranged on periodic table?
Dmitri Mendeleev and Lothar Meyer first arranged the elements in the increasing order of atomic masses. Bohr and Henry Moseley then arranged the elements in the increasing order of atomic number.
How are element arranged on a periodic table?
The elements are arranged in the increasing order of their atomic number and repeating properties.
How was mendeleev period table arranged?
Mendeleev arranged the elements are arranged in order of increasing atomic masses. He founded that properties of elements are periodic when arranged in this pattern.
