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.

What element has the longest name?

I think Praseodymium is the longest element name in the Periodic Table.

What is the link between plumbers and the periodic table?

'Lead'

The tradesman , plumber, comes from the fact that he/she contructed / mended lead water pipes. Today, the name refers to any tradesman dealing in pipework, usually copper, or olastic. and very rarely 'lead'.

The Latin name for ;Lead; is 'Plumbum' , Hence the 'Pb' as its elemental symbol .

What chemical compound is 3N2O?

The chemical compound 3N2O is nitrous oxide, also known as laughing gas. It is a colorless and non-flammable gas with a slightly sweet odor. Nitrous oxide is commonly used as an anesthetic in medical and dental procedures.

What is The first element on the periodic table of elements is hydrogen.?

The elements in the periodic table are arranged according to their atomic numbers, which are the numbers of protons in their atomic nuclei.

The atomic number of hydrogen is 1 because it's atoms have one proton, which is why it's the first element in the periodic table.

What is the most common letter in the periodic table out of all letters in a chemical symbol?

Through element no. 111, the most common letter out of all the symbols on the periodic chart is R (which occurs 16 times, second is S @ 13 times).

What is Carbon Trioxide used for if anything?

Carbon trioxide (CO3) is a hypothetical compound that has not been observed in nature or synthesized in a stable form due to its high reactivity. It is theorized to be highly unstable and likely to decompose into carbon dioxide and oxygen. Therefore, it does not have any practical applications and is primarily of theoretical interest in the field of chemistry.

How is the modern periodic table different from Dmitri mendeleev's table?

Well, honey, the modern periodic table is like the upgraded version of Dmitri Mendeleev's original creation. It's still got all the elements laid out in order of increasing atomic number, just like Dmitri did, but now it's organized based on atomic structure rather than just atomic weight. Think of it as the new and improved model - same concept, but with a few fancy updates.

What periodic elements make up fire?

Fire is not made up of periodic elements, as fire itself is a chemical reaction rather than a substance. However, the process of combustion typically involves the reaction of a fuel source (such as wood or gas) with oxygen in the air, producing heat and light. The main elements involved in combustion are typically carbon, hydrogen, and oxygen.

What is the cost of 1 gram of sodium?

The cost of 1 gram of sodium varies depending on the supplier and market conditions. As of the current market prices, the cost of 1 gram of sodium is typically around $0.30 to $0.50. However, prices can fluctuate due to factors such as demand, supply chain disruptions, and economic conditions.

What volume of oxygen will remain after reacting 8cm3 of hydrogen with 20cm3 of oxygen?

To determine the volume of oxygen remaining after the reaction, we first need to determine the stoichiometry of the reaction. The balanced chemical equation for the reaction of hydrogen and oxygen is 2H2 + O2 -> 2H2O, meaning 2 volumes of hydrogen react with 1 volume of oxygen to produce 2 volumes of water vapor. Since the reaction ratio is 2:1 for hydrogen to oxygen, the 8cm3 of hydrogen will react with 4cm3 of oxygen. Therefore, the initial 20cm3 of oxygen minus the 4cm3 used in the reaction leaves 16cm3 of oxygen remaining.

Who organized the very first periodic table?

The first periodic table was organized by Dmitri Mendeleev in 1869. Mendeleev arranged elements according to their atomic weight and properties, leaving gaps for unknown elements that were later discovered.

What does Ni mean in the periodic table?

Ni on the periodic table represents the element Nickel. It is a transition metal with atomic number 28. Nickel is commonly used in various industrial applications due to its properties, such as corrosion resistance and high ductility.

Which family does technetium belongs to?

Technetium belongs to the transition metal family on the periodic table. It is a d-block element with the atomic number 43. Transition metals are known for their variable oxidation states and their ability to form colorful compounds. Technetium is a synthetic element and is commonly used in nuclear medicine.

What characteristics do metalloid elements share with metal and non metal elements?

Well, metalloids are like the happy little bridge between metals and non-metals. They have some properties of metals, like being shiny and good conductors of electricity, but also some properties of non-metals, like being brittle and not as good at conducting as metals. Just like in painting, each element brings its own unique qualities to the canvas of the periodic table.

Why does the atomic radius decrease when going from left to right on the periodic table?

Oh, dude, it's like this: as you move from left to right across the periodic table, you're adding more protons to the nucleus, which increases the positive charge and pulls the electrons closer. So, yeah, the atomic radius decreases because those electrons are getting sucked in tighter. It's like trying to hug someone with a strong magnetic force pulling you in – not much room for a big ol' bear hug anymore!

Why do some elements have a symbol with two letters?

Since there are only 26 letters in the alphabet and there are (currently) 111 known elements, therefore not every element can be represented by only 1 letter. Also some elements date back to antiquity and already have symbol names assigned by Alchemists, for instance, rather than being G, gold is Au for the Latin word aurum for shining dawn.

What is a row of elements across the periodic table called?

Well, darling, a row of elements across the periodic table is called a period. It's like a little family reunion where elements with similar properties get together and show off their atomic numbers in style. So, next time you see a row of elements lined up, just remember they're strutting their stuff in a period.

What is the mass of 42.6 mol of Si?

Well, isn't that a happy little question! To find the mass of 42.6 moles of silicon, you'll need to multiply the number of moles by the molar mass of silicon. The molar mass of silicon is approximately 28.0855 grams per mole, so when you multiply that by 42.6 moles, you get a mass of about 1197.6 grams. Just like painting a beautiful landscape, it's all about following the right steps with a touch of joy and curiosity!

What is Zu on the periodic table?

There is no element labeled "Zu" on the periodic table. If you're looking for an element symbol, it may not exist in the current periodic table. If you provide more context or details, I may be able to help you further.

What element is in period 6 in the same group as Mg?

Ah, what a lovely question! In period 6, the element in the same group as Magnesium (Mg) is Barium (Ba). Both of these elements share similar chemical properties due to being in the same group on the periodic table. Isn't it fascinating how elements can show such wonderful patterns and relationships?

What is group 11 on the periodic table?

Group 11 on the periodic table consists of the elements copper (Cu), silver (Ag), and gold (Au). These elements are also known as the coinage metals or noble metals. They are characterized by their high ductility, conductivity, and resistance to corrosion. Group 11 elements have one electron in their outermost shell, making them highly reactive and capable of forming stable +1 oxidation states.

Which are radioactive elements in periodic table?

All elements have at least some radioactive isotopes.

For some elements no radioactive isotopes are known except those that are synthetic (see link to related question below).

For some other elements, there are both radioactive isotopes and stable isotopes in nature. (see link to related question below).

Some elements only have radioactive isotopes, and these are found in nature in at least trace quantities, they include (ordered by atomic number; those marked with * are normally only found in trace amounts in ore as radioactive decay products, and those with ** are distributed radioactive decay products found in trace amounts):

Period 5: technetium*

Period 6: promethium*, bismuth, polonium*, astatine*, radon**

Period 7: francium*, radium*, actinium*, thorium, protactinium*, uranium, neptunium*, plutonium**

The fact that all isotopes of bismuth are radioactive was only recently discovered.

Some elements are only know as a result of synthesis by human activity, and these are as follows:Period 7: americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrencium, rutherfordium, dubnium, seaborgium, bohrium, hassium, meitnerium, darmstadtium, roentgenium, copernicium, and anything new that might come along.

The longest word you can make out the period table ever?

Oh honey, the longest word you can make using symbols from the periodic table is "Tungsten (W), Uranium (U), Nitrogen (N), Sulfur (S), and Hydrogen (H)" which spells out "WuNSH." But let's be real, it's not like you're going to be winning any spelling bees with that gem.
