Periodic Table

They react with water to form metal hydroxides which makes the solution basic, or alkaline. For example, sodium plus water produces sodium hydroxide plus hydrogen.

2Na + 2H2O ---> 2NaOH + H2

Gold (Au) is located in Group 11 and Period 6 of the periodic table.

Lithium got its name from the Greek word "lithos," meaning stone. This is because lithium is commonly found in various types of rocks and minerals.

Carbon belongs to the oxygen family, also known as group 14 in the periodic table. The elements in this group share similar chemical properties, such as forming covalent bonds and having varying oxidation states.

A compound is formed by the chemical combination of two or more elements. These elements chemically bond together in fixed ratios to create a substance with unique properties different from the individual elements.

Helium shares the most characteristics with neon because both elements are in the same group on the periodic table (Noble Gases). They both have a full outer electron shell, making them stable and nonreactive.

In the periodic table, a period would be a horizontal row, so named because it was noticed that as the atomic number increased, the elements would periodically evidence similar chemical properties and could thus could be grouped in a way that manifest these similarities. This quality is explained by how electrons fill their orbitals as you progress across the period; elements in the columns having some chemical similarites to others in their column.

Vedanta Aluminium & Power Business is India's largest green metal producer, the second most vital metallic in the world. Backed by means of wealthy deposits of remarkable bauxite, India has the second biggest aluminium manufacturing ability in the world after China. We produce more than 1/2 of India's aluminium at 1.nine million tonnes consistent with annual (MTPA) in FY20. We command more than 40% marketplace percentage in India and our value-introduced merchandise are global leaders in their respective segments. This commercial enterprise is likewise among the biggest non-public energy manufacturers in India with an ability of over 5300 MW.

Lead is the heaviest non-radioactive element. It was previously thought to be Bismuth, but in 2003, it was found to be weakly radioactive with a half-life of about 19 quintillion years (19 billion billion years). Because of it's ridiculously long half-life, Bismuth can be treated as if it is stable, but it will eventually decay into Thallium.

Atomic size decreases across the period from sodium to argon due to increasing nuclear charge, which attracts the outermost electrons more strongly, pulling them closer to the nucleus. This results in a smaller atomic size as you move from left to right across the period.

The elements most commonly found in organic compounds are carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur and phosphorus. Carbon and hydrogen are the primary elements in organic molecules, while oxygen, nitrogen, sulfur, and phosphorus can also be present in varying amounts depending on the specific compound.

Bromine is an example of a non-metal that is liquid at STP (Standard Temperature and Pressure).

potassium permanganate

Copper--Cu, atomic number 29--is in Group 11 Period 4.

Chemical symbols are these days given 1-, 2- or 3-letter symbols based on some letters in their name or name in Latin. For example H is Hydrogen, Ca is calcium and Uuo is Ununoctium. Or, from the Latin names, Fe is Iron, K is Potassium and Ag is Silver. It appears that different symbols were used in the past, rather like diagrams that are used for the planets or male and female symbols.

each group of the periodic table consists of elements that resemble each other. for instance Lithium, sodium, potassium, and a few more a grouped together, are called the alkali metals. These are all highly reactive, thus they are in a group. Furthermore group also determines the number of valence electrons are present in some cases. Hope that answered your question.

when you have an element such as B or Boron its atomic number is 5. you have to add that with a element that has a atomic number that the sum of 5 and that element must be 8...this is the octete rule....therefore boron would combine with Lithium. one you may be familiar with is hydrogen and oxygen.they do not apply to this rule.

any except for bromine, mercury, nitrogen, oxygen, fluorine, helium, neon, argon, krypton, xenon, radon, hydrogen, chlorine.

And then we are unsure of the states of (rutherfordium, dubnium, seaborgium, bohrium, hassium, meiternium, darmstadium, roentgenium, copernicium, flevourium, and livermorium.

Hope this helps.

Vertical columns are called groups.

Horizontal rows are called periods.

The most reactive nonmetals are located in Group 17 of the periodic table, known as the halogens. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive due to their strong tendency to gain electrons to achieve a full outer electron shell.

When two elements have the same atomic number, it means they are isotopes of each other. Isotopes have the same number of protons but different numbers of neutrons in their nuclei. This results in subtle differences in their atomic mass and stability.

It was recognized by the inventor of the Periodic table that these empty spaces are for elements/isotopes that would be discovered someday. Dmitri Mendeleev is generally credited with the publication, in 1869, of the first widely recognized periodic table. He developed his table to illustrate periodic trends in the properties of the then-known elements. Mendeleev also predicted some properties of then-unknown elements that would be expected to fill gaps in this table.

The physical properties and the physical state of the materials can be perceived by our senses.

Color, reflectivity, opacity, shape, feel, texture, temperature, smell, volatiles given off, solid/liquid/gas, viscosity, tackiness, homogeneity, heterogeneity, movement in relationship to the environment (sight, sounds, feel), tension, waves, heat conductivity & surface area, etc.

A few elements past iron can form in the star by neutron capture and beta decay. However the majority can only be formed by the blast shockwave of a supernova, which can form elements significantly beyond Uranium.
