How are the elements arranged in the modern periodic table Check all that apply.?
The elements are arranged in order of increasing atomic number, which corresponds to the number of protons in the nucleus of an atom. Elements with similar properties are grouped together in columns called groups or families. The periodic table is divided into blocks: s-block, p-block, d-block, and f-block, based on the electron configuration of the elements. The periodic table is organized into periods or rows, which correlate with the energy levels or shells of the electrons of the elements.
What major change occurs as you move left to right on the periodic table?
As you move left to right on the periodic table, the number of valence electrons an element has increases. The number of valence electrons an element has corresponds to which group (column) an element is. (This rule does not apply to transition metals...)
Why was newlands law of octavaces rejected?
Newlands' Law of Octaves was rejected primarily because it was based on the observation of only 56 elements, which limited its applicability. While it successfully grouped elements with similar properties in the first few rows, it failed to accommodate new elements discovered later and did not apply well to heavier elements. Additionally, the law suggested that elements' properties repeat every eight elements, which was not universally accurate. This led to the development of the periodic table as a more comprehensive framework for organizing elements based on atomic number and properties.
What elements are the most abundant in living organisms Select all that apply.?
The most abundant elements in living organisms are carbon, hydrogen, oxygen, and nitrogen. These elements are essential for forming the organic molecules that make up cells, such as carbohydrates, proteins, lipids, and nucleic acids. Additionally, sulfur and phosphorus, while less abundant, also play vital roles in biological processes. Overall, these elements are crucial for the structure and function of living systems.
Why did Dobereiner's triads table fail?
Dobereiner's triads table failed primarily because it was based on the observation of only a limited number of elements, which did not universally apply across the entire periodic table. His method of grouping elements into triads based on similar properties and their atomic weights did not consistently yield accurate predictions for all known elements. Additionally, as more elements were discovered, the relationships between atomic weights and properties became increasingly complex, highlighting the inadequacies of his approach. Ultimately, the development of a more systematic and comprehensive periodic table by later scientists, notably Mendeleev, rendered Dobereiner's triads obsolete.

Who was the Russian scientist who discovered a set of patterns that apply to all elements?
Dmitri Mendeleev was the Russian scientist who discovered the periodic law and created the first version of the periodic table in 1869. He arranged the known elements by their atomic mass, demonstrating a periodic arrangement of properties that revealed recurring patterns.

Why isn't glass on the periodic table?
Plastic is a compound, not an element. It is made mainly from carbon, hydrogen, and oxygen, all of which are elements found on the Periodic Table of Elements.
