Periodic Table

Transition metals tend to be less reactive than alkali metals or alkaline earth metals. They often form colorful compounds, have multiple oxidation states, and can act as catalysts in chemical reactions. However, some transition metals can still react with certain elements or compounds under the right conditions.

No, alcohol does not dissolve salt better than water. Water is a better solvent for salt because of its polar nature, which allows it to break apart the ionic bonds in salt and dissolve it more effectively. Alcohol is less polar and not as effective at dissolving ionic compounds like salt.

Elements 110, 111, and 112 have been named. Element 110 is now called darmstadtium with the symbol Ds. Element 111 is now called roentgenium with the symbol Rg. Element 112 is now called copernicium with the symbol Cn.

Tungsten's chemical symbol is W because it comes from its older, German name "Wolfram." In the early 19th century, tungsten was often referred to as wolfram in Europe, and the symbol W was chosen to represent this element on the periodic table.

The elements were arranged according to atomic number. And atomic number is equal to the number of protons and electrons.

There is a rule (octet rule), which states that for an atom to be stable, it needs 8 electrons.

The First Group has one excess electron to be stable. Group 7 needs one electron to be stable.

(in short... 1-1=0(stable), 7+1=8(stable))

Group 8 has 8. So it is stable, and located at the end of the table.

"Wrestled with the table" typically means struggling or having difficulty with a physical object or piece of furniture, such as trying to move it, assemble it, or fix it. It may suggest a challenging or frustrating task that requires physical effort or problem-solving skills.

Lawrencium is a synthetically prepared element, a metal, has an atomic mas of 103, and is one of the Actinides.

Yes, generally the electronegativity of elements increases as you move from left to right across a period on the periodic table. This trend is due to the increased nuclear charge and decreased atomic size as you move across the period, which results in stronger attraction for electrons.

Lanthanides and actinides are placed at the bottom of the periodic table to avoid significantly expanding the table and making it less practical. Placing these two series below the main body of the table helps keep the table compact and easier to use. Additionally, these elements have similar electron configurations, which is why they are grouped together in this way.

Yes, table runners are typically shorter than the table they are placed on. They are meant to run along the center of the table, leaving some space on either end for a balanced look. A general guideline is for the table runner to be about two-thirds the length of the table.

Gallium and germanium were important to Mendeleev because their properties fit well into his periodic table, filling the gaps he had predicted based on the patterns of other elements. The discovery and confirmation of these two elements helped validate his periodic law and strengthen his periodic table's credibility.

Table skirting adds a polished and professional look to any event by covering unsightly table legs and providing a sleek backdrop. Table setting is important for creating an inviting and organized dining experience, ensuring that guests have the necessary utensils and plates for their meal. Both elements contribute to the overall aesthetics and functionality of a dining or event space.

Technetium is considered an extinct isotope, as is promethium. Their abundence is pretty much zero.

The largest atom is francium and has 87 protons and 87 electrons.

The periodic table is a tabular arrangement of the chemical elements organized by their atomic number, electron configuration, and recurring chemical properties. It provides a systematic way to categorize and display the elements based on their shared characteristics and relationships.

Elements on the periodic table are arranged by atomic number. This refers to the number of protons in the nucleus of that atom. Generally, atoms with higher atomic numbers will have a higher mass (due to more protons); however, the number of neutrons in the nucleus (isotopes of each element) will also affect the mass. An element with a lower atomic number but extra neutrons could have a higher atomic mass than an element with a higher atomic number. The atomic mass listed on the periodic table is an average of the naturally occurring distribution of isotopes of that element. For example, Cobalt (element #27) has an atomic mass of 58.9332 amu, whereas Nickle (element #28) actually has a lower atomic mass of 58.6934 amu.

Boron has the greatest ionization energy among aluminum, boron, and carbon. This is because boron has a lower atomic size compared to aluminum and carbon, leading to increased electronegativity and stronger attraction for electrons in the atomic structure.

Third alkali metal is potassium and first transition metal is scandium.

Lithium (Li) has an atomic number of 3, meaning it has 3 electrons. When an atom loses electrons, it forms a positive ion, so for Li to become a Li+ ion, it must lose 1 electron, leaving it with 2 electrons.

Yes. It's called The Periodic Table of Elements.

Seldom do they have similar physical properties - many of those depend on atomic mass and related properties, and they increase down the group. Chemically, they are similar mostly because their outer (valence) electronic structure is the same.

Groups 1-12 on the periodic table are known as the "main group elements" or "representative elements." These groups include elements with varying chemical properties and are found in the s and p blocks of the periodic table. They are important for forming compounds and ions with different valences.

The oldest elements in the universe are also the simplest and most abundant: hydrogen and helium. They were first formed after the big bang approximately 14 billion years ago. All of the other elements were created in the cores of stars, which were formed several million years after the big bang event.

Eka-aluminum corresponds to the element gallium on the modern periodic table. Eka-aluminum was a placeholder name given by Dmitri Mendeleev for an element that he predicted would have properties similar to aluminum but with a higher atomic mass. Gallium, discovered in 1875, fits these properties and is known as eka-aluminum's modern counterpart.

The element carbon has the ability to link with itself in long chains containing from two up to hundreds of units. It can also form rings and bond with many other elements and they often with each other. This ability means that many millions of possible compounds can be formulated. The chemistry of carbon is called organic chemistry as life is based upon it.
