Which scientist placed the periodic table in order of the number of protons in the atom?
Dmitri Mendeleev, a Russian chemist, organized the periodic table in the manner that we know today. Initially, he organized them by increasing Atomic Mass, but that caused a few mis-matches. Later, he re-organized them by increasing atomic number, and it made more sense. His organizational skills helped us to predict the properties of elements unknown during his time. Turns out they fit right in where they should, upholding his brilliant creation.

How can you find an element?
I'm assuming you mean "how can you find an element on the periodic table?" The periodic table is strategically placed. You can either look for the atomic number (the number at the top-- the number of the protons in one atom), or you can just look for the Element Symbol. The periodic table from left to right is sorted by increasing atomic number. The periodic table from top to bottom is sorted by increasing number of energy levels (the levels in which the electrons are in).
How are the elements arranged in the periodic table by atomic mass or atomic number?
The elements in the periodic table are arranged by atomic number, which represents the number of protons in an atom's nucleus. This arrangement creates groups and periods that help categorize elements based on their properties and characteristics. Additionally, elements with similar properties are placed in columns called groups.
What is the present basis of arranging in the elements in the periodic table?
The elements in the periodic table are arranged by increasing atomic number, which is the number of protons in the nucleus of an atom. This arrangement helps group elements with similar properties into columns called groups or families, and elements with the same number of electron shells into rows called periods.
Why is it extremely unlikely that a new element will be discovered that fits between sodium and magnesium on the periodic table?
What makes each element unique is the number of protons in the nucleus. Sodium has 11 protons and Magnesium has 12 protons. The periodic table is arranged with the number of protons of each element increasing to the right and down the table. For an element to fit between sodium and magnesium it would have to have fewer than 12 protons but more than 11, which is simply not possible.
Why are things grouped together on the periodic table?
-An element is placed in that group of periodic whose group number is equal to the number of valence electrons.
Why is hydrogen placed first in the periodic table?
Because It has 1 proton. The elements on the periodic table are order by the number of protons.
Why calcium is placed after potassium?
The periodic table is arranged by atomic number, which is the number of protons in the nucleus of an atom. Potassium has an atomic number of 19, while calcium has an atomic number of 20. This is why calcium is placed after potassium in the periodic table.
How does a new element get put on the periodic table?
The key defining characteristic between elements is the number of protons their atoms have. The periodic table is organized by increasing atomic numbers which are the number of protons each atom has. So a new element would be given an atomic number equal to the number of protons it has, then placed wherever it lands in numerical order with the all the existing elements.
How are isotopes placed in the periodic table?
Isotopes and their prevalence are not shown on the periodic table. Instead, the atomic weight shown for each element is an average of the atomic weights of all naturally-occurring isotopes (calculated from percentages occurring on Earth).
Where are the isotopes of the same elements having different atomic masses placed in the periodic table?
Isotopes of the same element with different atomic masses are placed in the same position on the periodic table because they have the same number of protons and electrons. The atomic number, which determines an element's position on the periodic table, is the same for all isotopes of an element.
What appears above sodium in the periodic table of element?
Above sodium in the periodic table of elements is lithium. Lithium has an atomic number of 3, while sodium has an atomic number of 11. This means that lithium has 3 protons in its nucleus, while sodium has 11.

The periodic table is based on an element's what?
The periodic table is based on an element's atomic number, which is the number of protons in the nucleus of an atom. Elements are arranged in order of increasing atomic number, which also dictates their unique placement in the periodic table.
Why are isotopes not found on different sections of the periodic table?
Isotopes are not found on different sections of the periodic table because isotopes have the same number of protons and electrons as the element they correspond to, so they are placed in the same position on the table based on their atomic number. The different isotopes of an element have a different number of neutrons, which affects their atomic mass but not their position on the periodic table.

HOW ARE ELEMENTS ARE THE PERIODIC TABLE ARRANGED?
The elements are arranged in order of increasing atomic number in the Periodic Table. The rows are called periods and the columns are called groups.

The elements in the periodic table are arranged by increasing atomic number, which is the number of protons in the nucleus of an atom. This arrangement helps group elements with similar properties into columns called groups or families, and elements with the same number of electron shells into rows called periods.
