How did chemist change mendeleevs perioic table in the early 1900s?
Chemists in the early 1900s made changes to Mendeleev's periodic table by rearranging elements based on their atomic number instead of atomic mass, leading to the development of the modern periodic table. This change accurately emphasized the relationship between an element's properties and its atomic number, rather than its atomic mass, and helped to better organize the elements.
What are the key differences between metals and non-metals on the periodic table?
Metals are typically shiny, malleable, and good conductors of heat and electricity. They are found on the left side of the periodic table. Non-metals, on the other hand, are usually dull, brittle, and poor conductors. They are located on the right side of the periodic table.
Describe the trends in the bond length between hydrogen and halogens?
The bond length between hydrogen and halogens decreases as you move down the halogen group on the periodic table. This is due to the increase in atomic size and electron shielding, leading to weaker hydrogen-halogen bonds. Additionally, bond length tends to increase in strength as you move left to right across the periodic table due to increasing electronegativity.
What is the differences between periodic table that Mendeleev and Moseley created?
The periodic table created by Mendeleev in 1869 was based on atomic mass and grouped elements with similar properties together. Moseley improved upon this by arranging elements based on atomic number, leading to the modern periodic table where elements are arranged in order of increasing atomic number, which is the number of protons in the nucleus. This organization better reflects the physical and chemical properties of elements.
What are the similarities and differences between the different blocks of the periodic table?
The periodic table is divided into blocks based on the electron configurations of the elements. The main blocks are s, p, d, and f. Similarities: Elements within the same block have similar chemical properties. Elements in the same block have the same number of valence electrons. Differences: The s-block elements are in groups 1 and 2, the p-block elements are in groups 13-18, and the d-block elements are in groups 3-12. The f-block elements are the lanthanides and actinides, which are placed below the main body of the periodic table.

What is the differences between repetitive and periodic motion?
Repetitive motion means the action is repeated again after a brief period of time where as periodic motion means it repeats after a fixed period of time.
