he arranged his Periodic Table by each elements Atomic Mass
What else can I help you with?
How was the person who devised the first periodic table able to predict the behavior of elements such as gallium scandium and germanium that had not even been discovered yet?
The reason the periodic table was created in the first place was to illustrate the "periodic" physical properties of the known elements of the time. Because of this, the properties of elements that were "missing" from the table could be extrapolated from the periodic trends seen in the known elements.
What is an anion and where can you find it on the periodic table?
anions are negatively charged species anions are not seen on the Periodic Table. however the elements on the right end of the periodic table (except for noble gases, group 18) have a strong tendency to accept electrons are become anions
What is the only letter in the alphabet not included on the periodic table of elements?
J is the only letter not present in the periodic table. Q is only seen once (ununquadium), as are X (xenon) and V (vanadium), but every other letter of the alphabet is present.
What is KL in chemistry?
KL is often used as an abbreviation for potassium iodide, a chemical compound composed of potassium and iodine. It is commonly used in laboratories for various chemical reactions and in medical settings as a source of iodine.
How many elements are there in the second period of the periodic table?
Eight. In order as would be seen in the second period on the periodic table, they are Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), and Neon (Ne).
Which group on the periodic table does not follow the normal trends and is often ignored?
The group of noble gases (Group 18) does not follow the normal trends seen in other groups on the periodic table. This is because they have full outer electron shells, making them very stable and unreactive compared to other elements.
How many tables are in the periodic table?
The periodic table is just ONE table. There are not sub-tables. The periodic table is divided into periods (the horizontal rows of the table) and groups (the vertical columns). As you move horizontally across the table, an increase is the atomic number is seen, along with trends in acidity, bonding behavior, and reactivity. The groups are arranged to contain elements that have similar properties. For example, Group 1 is called the alkali earth metals group; all are light, highly reactive metals. Many more trends and groupings exist.
What is a trend seen in the periodic table?
electronegativity
What are the names of things seen in the periodic table?
Elements
What trends were seen in Mendeleev?
In Mendeleev's periodic table, several key trends were observed, including the periodicity of element properties such as atomic mass, reactivity, and valence. He arranged elements in order of increasing atomic mass, which revealed recurring patterns in their chemical behavior. Mendeleev also left gaps for undiscovered elements, predicting their properties based on the trends he observed, which demonstrated the predictive power of his periodic arrangement. This laid the groundwork for the modern periodic table, where elements are organized by atomic number.
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.

Why do elements appear more than once in the periodic table?
The modern periodic table doesn't, but someone probably organized the periodic table by characteristics. A few elements have multiple characteristics of various groups or periods.... Ergo, it would be fitting to place an element in multiple spots of the table as seen fit. Hope this helps (:
What is an anion and where can you find it on the periodic table?
anions are negatively charged species anions are not seen on the Periodic Table. however the elements on the right end of the periodic table (except for noble gases, group 18) have a strong tendency to accept electrons are become anions
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What does CPI stand for in the periodic table of elements?
CPI stands for Continuous Plating Index. It is a measure used in electrochemistry to determine the ability of a metal to plate out of a solution onto a cathode. It helps predict the likelihood of a metal depositing onto a surface during plating processes.
Do you see any pattern in the nature and properties of elements as they are listed in the periodic table?
Yes, there are clear patterns in the periodic table known as periodic trends. These include trends in atomic size, ionization energy, electronegativity, and chemical reactivity as you move across and down the table. These trends are a result of the periodicity in the elements' electronic configurations.
