What else can I help you with?
Is it true or false that Mendeleev and other scientists were able to use the periodic table to predict the properties of undiscovered elements?
True. Mendeleev and other scientists used the periodic table to predict the properties of undiscovered elements based on their position in the table. This led to the successful discovery and confirmation of elements like gallium and germanium.
What scientific skill was used when scientists grouped chlorine with other natural elements?
Classification was used when scientists grouped chlorine with other natural elements in the periodic table based on their properties and characteristics.
Why were other scientists skeptical about mendeleev?
Other scientists were skeptical about Mendeleev's periodic table because it contained gaps for elements that had not yet been discovered and because it did not follow strict atomic weights as a basis for organization. Additionally, there was skepticism about his prediction of the properties of undiscovered elements.
What would happen if you didnt have the periodic table?
Without the periodic table, scientists would have a harder time organizing and understanding the properties of elements. It would be challenging to predict how elements would react with each other and to develop new materials. Progress in chemistry and other fields reliant on the periodic table would be hampered.
What were the three missing elements in the periodic table?
See "Mendeleev's predicted elements" in Wikipedia The answers are: scandium (Sc - 21), gallium (Ga - 31), technetium (Tc - 43), and germanium (Ge - 32) He temporarily named them to be: ekaboron (Eb), ekaaluminium (El), ekamanganese (Em), and ekasilicon (Es).
What is a large table that scientists use to find out information about metals and other elements?
The periodic table of elements
What is the difference between synthetic elements and other elements?
Synthetic elements are those which have been produced by scientists in a laboratory, but not yet discovered occurring naturally. They are true elements because they occupy missing spaces on the periodic chart....they adjust the number of electrons, i.e., in one element to create another.

How many years after Robert boyle did it take scientists to formulate the periodic table of elements?
It took about 160 years after Robert Boyle's time for scientists to formulate the periodic table of elements. The periodic table was created by Dmitri Mendeleev in 1869, building on the work of many other chemists who contributed to our understanding of elements and their properties in the intervening years.
What have predictable chemical properties?
Elements in the periodic table have predictable chemical properties based on their position because they have the same number of valence electrons. This determines how they will react with other elements and molecules. The periodic table's structure helps scientists predict the behavior of elements based on their properties.

Who invented piriodic table?
Dmitri Mendeleev created the first periodic table according to atomic mass in 1869. Others before Mendeleev had organized the elements according to their properties and were able to discern periodicity, although Mendeleev is generally accepted as the creator of the table.With the information he gathered about the elements, he was able to see that there were missing elements that hadn't been discovered. He could figure out the atomic masses of the missing elements by averaging the atomic masses of the elements above and below the missing one. One such element, which he called "eka-silicon" (eventually Ge) was missing, but with understanding of the patterns the periodic table made, he predicted the elements appearance, melting point, atomic mass, density, formula of oxide, and formula of chloride.Throughout the years, other scientists were able to find or create these missing elements to form the table we know today. Today's periodic table is ordered by atomic number instead of atomic mass (as Mendeleev had started). Henry Moseley was the first to order the elements by atomic number so elements would fit together in groups/families and periods better in 1913.
Did Arsenic create the first periodic table?
Arsenic did not create the first periodic table. The first periodic table was created by Dmitri Mendeleev, a Russian chemist, in the 1860s. Other scientists had organized elements in other ways prior to the invention of Mendeleev's periodic table, but the other methods were criticized and did not catch on.
How does the periodic table relate to matter?
The periodic table categorizes elements based on their atomic structure, which influences their physical and chemical properties. This organization helps scientists predict the behavior of elements and how they interact with other elements to form compounds, thus providing valuable information about the properties of matter.
