Periodic Table

Ore is not a metal itself; it is a natural material from which metals can be extracted. Ores typically contain one or more metals in combination with other elements, such as oxygen, sulfur, or carbon. The metal is separated from the ore through processes like smelting or leaching.

Exceptionally inert gases belong to Group 18 (Noble gases) in the periodic table. They are inert because their outermost electron shells are full, making them stable and less likely to form chemical bonds with other elements. This full electron shell configuration results in low reactivity, hence their classification as inert gases.

Hahnium was a proposed name for element 105 but was rejected by IUPAC in favor of (Db) dubnium.

Sugar and water-ice are common examples of a molecular solid. In general terms, a molecular solid is held together by Van Der Waals forces (bonds) which are rather weaker than ionic or covalent bonds.

Oxygen would form an ionic bond with lithium.

NaC6H5COO is the chemical formula for sodium benzoate. It is a salt derived from benzoic acid that is commonly used as a preservative in food and beverages. Sodium benzoate helps inhibit the growth of bacteria, yeasts, and molds, prolonging the shelf life of products.

A table is in 1NF (First Normal Form) when each column contains atomic values (indivisible values), there are no repeating groups of columns, and each row is unique.

they're all cloud levels...

i mean orbitals

the first two rows are S cloud, the middle (transition metals) is the D cloud, the six rows on the left are the P cloud and the lanthanide series is F cloud

Helium is the element that fits this description. Helium is a colorless, odorless, and non-reactive gas that does not conduct electricity. It has a density of about 90 mg/L at room temperature and pressure.

Gold can be found naturally as veins running throughout granite and quartz, or with the element tellurium.

Samarium is a metal. It is a rare earth element with properties characteristic of metals, such as being shiny, malleable, and having good electrical conductivity.

A lookup function like VLOOKUP or INDEX/MATCH can be used to find the answer located in a vertical table. VLOOKUP searches for a value in the first column of a table and returns a value in the same row from a specified column, while INDEX/MATCH combination can retrieve a value at the intersection of a certain row and column based on matching criteria.

Yes, it is common in Mexican culture to place their hands on the table during a meal. It is a sign of openness and readiness to engage in conversation. However, it is always important to be mindful of local customs and etiquette when dining in a different culture.

A literal table is a table in a database where the data is directly specified in the SQL query rather than being stored in a separate database table. This can be useful for temporary or small datasets that do not need to be stored persistently.

Neon was discovered in 1898 by Sir William Ramsay and Morris Travers, but it was formally added to the periodic table in 1904 by Sir William Ramsay. Neon is classified as a noble gas and has the atomic number 10.

You can label contrast media by writing the patient's name and identification number on the label provided with the contrast media or by affixing a pre-printed sticker with the necessary information onto the contrast media container.

These letters are chemical symbols for the chemical elements:

Ca - chemical symbol of calcium

F - chemical symbol of fluorine

I - chemical symbol of iodine

I suppose that the molecule CaFI was not surely confirmed.

Another name for the columns in the periodic table is "groups." These groups are numbered from 1 to 18, and each group shares similar chemical properties due to the arrangement of electrons in their outer energy levels.

The size of each column will determine the width of the column in the table. Adjusting the size of each column allows you to control how much space each column takes up in the table, making it easier to display information in a structured and organized way.

Phosphorus is an element that can burn without oxygen through a process called spontaneous combustion. When exposed to air, phosphorus can react with the oxygen in the air to produce phosphorus oxide and ignite.

Carbonates would generally react faster as powder compared to lumps due to the increased surface area available for the reaction to occur. More surface area allows for more contact between the reactants and speeds up the reaction process.

Yes. Some have 3 letters. They are not official names or abbreviations, but placeholders until they are named properly.

Uut, Ununtrium

Uuq, Ununquadium

Uup, Ununpentium

Uuh, Ununhexium

Uus, Ununseptium

Uuo, Ununoctium

It can keep going like this forever, but these are the ones that have already been discovered.

Copper compounds emit green light when heated due to a phenomenon called thermal luminescence. This occurs because as the compounds absorb heat energy, the electrons in the copper atoms become excited and move to higher energy levels. When the electrons return to their original energy levels, they release the excess energy in the form of light, often in the green wavelength range.

Fe on the periodic table (element 26) is short for the Latin word for iron.
