Periodic Table

Bunsen and Kirchhoff discovered caesium in 1860 by using a spectroscope to analyze the mineral water from Durkheim, Germany. They observed a new blue spectral line which they attributed to a new element, caesium. They then isolated the element through chemical processes.

Among the metals on the periodic table, gold is considered one of the most stable due to its resistance to oxidation and corrosion. Gold does not react easily with other chemicals or elements, making it highly valued for use in various applications, including jewelry and electronics.

To write formulas for complex ions, start by writing the symbol of the central metal cation. Then, add the ligands around the central metal cation. Use coordination numbers and oxidation states to balance the charges of the ions within the complex. Finally, enclose the entire complex in square brackets and indicate the charge outside the bracket.

Neptunium's symbol is Np because it is named after the planet Neptune. It is a synthetic element not found in nature and was named after Neptune due to its proximity in the periodic table to uranium, which is named after the planet Uranus.

The formula for dinitrogen pentoxide is N2O5. It is an unstable and highly reactive nitrogen oxide compound.

Yes, Mendeleev noticed that elements with similar properties tended to repeat at regular intervals when arranged by atomic mass, forming groups or columns in his periodic table. This led him to predict the properties of undiscovered elements and leave gaps in the table for them.

it has two element (hydrogen and helium) that are both gases although they are metallic and have a luster like tony baloney

If you mean elements, there are six members of the halogen family; fluorine, chlorine, bromine, iodine, astatine, and element 117. Element 117 has not yet been officially named. It is currently called ununseptium, Uus, which means 117.

The element with atomic number 55 on the periodic table is cesium.

Some common compounds include water (H2O), carbon dioxide (CO2), sodium chloride (NaCl), sucrose (C12H22O11), ammonia (NH3), methane (CH4), sulfuric acid (H2SO4), hydrogen peroxide (H2O2), calcium carbonate (CaCO3), and glucose (C6H12O6).

The two periods below the periodic table are known as the lanthanides and actinides. These series consist of elements that fall within the f-block of the periodic table.

The periodic law establishes that elements are arranged in order of increasing atomic number in the periodic table, and elements with similar properties are grouped together in columns called groups. This law allows for the prediction of an element's properties based on its position in the periodic table.

Hiding columns in a table does not remove the data from the table; it simply hides the column from view. The data in the hidden columns remains in the table and can be unhidden at any time to display the data.

Steel is often considered a hard-wearing metal due to its durability, strength, and resistance to corrosion. It is commonly used in construction, machinery, and tools where high wear and tear is expected.

Group 1 metals, such as lithium, sodium, and potassium, are shiny, soft metals with a silvery appearance. They are highly reactive and tend to tarnish quickly when exposed to air, forming a dull oxide layer on the surface. Group 1 metals are typically stored under oil to prevent them from reacting with moisture and oxygen in the air.

1. Ionic compounds are composed of positively charged cations and negatively charged anions held together by electrostatic forces.
2. They have high melting and boiling points due to strong ionic bonds that require a lot of energy to break.
3. Ionic compounds are often soluble in water, as the polar water molecules can surround and stabilize the individual ions.

Noble gases (Group 18) are generally unreactive due to their full outer electron shells. They typically do not bond with other elements, as they are stable and satisfied with their electron configuration.

Coltan is not an element on the Periodic Table. Coltan is a mineral from which niobium and tantalum are extracted from.

The energy released in the mitochondrial electron transport chain is used to transport protons into the intermembrane space of the mitochondria. This creates a proton gradient that is utilized by ATP synthase to produce ATP through oxidative phosphorylation.

Ta stands for tantalum in the periodic table. Tantalum is a transition metal with atomic number 73 and is known for its high melting point and corrosion resistance.

"G" on the periodic table typically refers to the group number of elements, indicating the number of valence electrons an element has. For example, group 1 elements have 1 valence electron, group 2 elements have 2 valence electrons, and so on.

Elements are placed in a group based on their similar chemical properties, such as reactivity and valence electrons. Elements are placed in a period based on the number of electron shells they have. Each period corresponds to the electron shell number of the elements in that period.

Yes, you can "overdose" on bath salts.

They raise your body temperature to a dangerous level, as much as 108 degrees. Basically you are cooking your brain from the inside out. This is dangerous stuff and should be banned.

Umm... it isn't, all that much. Okay, the noble gases are, well, gases; I'll give you that: everything on the far right side is a gas. Other than that... There are two liquid elements; one of them (Hg) is at the bottom and horizontally in about the middle and the other (Br) is on the right and vertically in about the middle. Not really much of a pattern there; the ones in between are NOT liquids. The gaseous elements that aren't noble gases are indeed all at the top right (except hydrogen). However, there are only five of them, and it's at least as easy to remember "H, N, O, F, Cl" as it is to remember "upper right, except that it's not a square or triangle like you might expect but more of an L-shape with the long side on the top, and also hydrogen."
