Periodic Table
The Periodic Table is a tabular arrangement of the elements in increasing order oftheir atomic numbers, so that elements with similar properties are in the same column. There are 18 columns, called groups, and seven rows, which are called periods, in the modern periodic table. Questions about the Periodic Table: its history and creation, trends, groups/families, and periods are asked in our Periodic Table category.

Is the Sodium most reactive metal?
Sodium is one of the most reactive, but the number one spot would probably go to francium.
However, it is impossible to gather enough francium to demonstrate this reactivity, so the the title is usually given to cesium.
What are the correct members of group 3 of the periodic table Sc Y La Ac or rather Sc Y Lu Lr?
The correct members of group 3 of the periodic table are Scandium (Sc), Yttrium (Y), Lutetium (Lu), and Lawrencium (Lr). Actinium (Ac) is not a member of group 3, while Lanthanum (La) is part of the lanthanide series and not considered a member of group 3.
How can a base act like water?
Because water is amphoteric and acts like a Bronsted-Lowry base when mixed with an acid, it will gain a proton and produce hydronium. This is just as a base gains a proton and forms a conjugate acid.
Where is Metals are located here on the periodic table?
Metals are located on the left side of the periodic table, predominantly in the groups 1, 2, and 3, as well as in the transition metals in groups 3 to 12. They are characterized by properties such as high electrical conductivity, luster, and malleability.
What were the five properties Medeleev used in his table?
The five properties Mendeleev used in his table were atomic mass, chemical properties, valency (oxidation state), color, and density.
What makes inert gases different from the other groups in the periodic table?
Inert gases, also known as noble gases, have full valence shells of electrons, making them stable and unreactive. This stability is due to their complete octet of electrons. In contrast, other groups in the periodic table have varying numbers of valence electrons and are more likely to form chemical bonds with other elements to achieve stability.
Are anabolic pathways spontaneous?
You would expect a catabolic reaction to be spontaneous because this type of reaction involves the release of energy. You would expect reactions that require energy (anabolic reactions) not to be spontaneous due to the need for an input of energy.
Is krypton used to make computer chips?
Krypton is not used to make computer chips. Computer chips are typically made using semiconductors like silicon, which have specific electrical properties that make them well-suited for this purpose. Krypton is primarily used in lighting, such as in fluorescent lights and high-intensity discharge lamps.
Are elements in the periodic table organized by their atomic numbers or their average masses?
If we still had the modern day model of the Periodic Table, the elements wouldn't be arranged by metals, metalloids, or nonmetals, they wouldn't be in the same families, and periods, and they would just be scattered abroad the Periodic Table. Not a great situation. LOL! :D
Radium is a member of Group 2 on the periodic table, known as the alkaline earth metals group. This group includes elements such as beryllium, magnesium, calcium, strontium, and barium. Radium is a highly reactive metal that is radioactive.
Why does elctronegativity decrease as you go down a group on the periodic table?
the electron affinity decreases down the group because new electrons continuously add in a outer shells that are far away from nucleus,so these electrons are less attracted to the nucleus and that's why releases less energy when added
Are the elements S Si Ge and Au malleable and ductile?
Sulfur (S) is brittle, while silicon (Si), germanium (Ge), and gold (Au) are malleable and ductile. Malleability refers to the ability of a material to be shaped without breaking, while ductility is the ability to be stretched into a wire.
How many elments does the periodic table have?
Group 1:Alkali Metals*
Group 2:Alkaline Earth Metals
Groups 3-12: Transitional Metals
Groups 13&14: Unnamed
Group 15:Pnictogens or Pnicogens)
Group 16: Chalcogens
Group 17: Halogens
Group 18: Noble Gases
*excluding hydrogen (hydrogen is in its own group)
Which metals in the periodic table are malleable?
Most metals in the periodic table are malleable, meaning they can be hammered or pressed into thin sheets without breaking. Some common examples include gold, silver, copper, and aluminum.
How do the elements change as you go to the right along a row of the periodic table?
the elements change from right to left because group 1 has 1 electron in their highest energy level and group 2 has 2 electrons in the highest energy level and so on. The transition metals are a totaly different thing so dont worry about those.
Which racial groups have the largest families?
Statistically, Black and Hispanic families in the United States tend to have larger family sizes compared to other racial groups. Cultural norms and traditions within these communities often prioritize strong family ties and support networks. Additionally, factors like socioeconomic status and access to healthcare can influence family size across different racial groups.
What theory provides information concerning both molecular shape and molecular bonding?
The VSEPR (Valence Shell Electron Pair Repulsion) theory provides information about both molecular shape and molecular bonding. It helps predict the geometric shapes of molecules based on the arrangement of electron pairs around the central atom and takes into account the repulsion between electron pairs to determine the overall molecular shape.
What is used to order elements on a periodic table?
Elements on a periodic table are ordered based on their atomic number, which represents the number of protons in the nucleus of an atom. This yields a unique and systematic arrangement of elements according to their properties.
Yes, ununoctium is a metallic chemical element. It is a synthetic element and belongs to the group of the transactinide elements on the periodic table. Ununoctium is highly unstable and has only been produced in very small quantities in laboratory settings.
What group and period is americium located?
Americium is located in group 3 and period 7 of the periodic table.
Which elements are transition elements?
It may include lawrencium, actinium, lutetium, or lanthanum.
The whole group is copernicium (No. 112), rutherfordium, roentgenium, molybdenum, niobium, palladium, vanadium, iridium, seaborgium, zirconium, titanium, ruthenium, meitnerium, technetium, darmstadtium, tantalum, manganese, platinum, mercury, rhodium, scandium, cadmium, chromium, osmium, hafnium, rhenium, bohrium, hassium, yttrium, cobalt, nickel, copper, iron, tungsten, silver, gold, and zinc.
Are groups on the periodic table in the same state at room temperature?
No, groups on the periodic table may consist of elements in different states at room temperature. For example, Group 1 elements like sodium and potassium are metals, while Group 17 elements like fluorine and chlorine are gases.
What language is most used on the periodic table?
The language most used on the periodic table is English. However, chemical elements also have symbols that are derived from their Latin names or other languages, as a way to represent them with a single or two-letter code.
