Periodic Table

An element with an incomplete d subshell. Elements which have common cations with incomplete d subshells are also considered transition metals. Elements with incomplete f subshells are sometimes called "inner transition elements."

The number of protons, which are found in the nucleus of an atom.

The alien periodic table does not include alkaline earth metals, transition metals, lanthanides, and actinides because it is a conceptual representation that supposes the existence of different types of elements beyond the known ones on Earth. The purpose is to explore the idea of diversity in chemical elements and atomic structures that may exist in other realms or universes.

The first 20 elements of the periodic table are hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, and calcium.

The majority of metals are located on the left-hand side of the periodic table, in groups 1, 2, and 3 to 12 (transition metals). Some metals are also found in the lanthanides and actinides series at the bottom of the table.

If you have buttons on a tab, it could be called a group of buttons. It you have multiple tabs with buttons, you have a group of tabs.

118 total - 92 natural elements

= 26 elements that do not naturally occur
===========================

none of the elements in the periodic table have a charge unless they gain (- charge) or lose (+ charge) an electron, or they can get delta charges which depends on what they are bonded too, that is what i learned in A2 chem a few monthes ago

The above information is absolutely correct... but here is a bit more information specifically for group 1A elements. All elements in group 1A can have a +1 charge as ions. Group 1A elements, such as sodium (Na), have 1 valence electron in their outer shell. When forming ionic compounds, sodium ions tend to donate this one electron to an element (in ionic form) that has 7 electrons in its outer shell. Thus, satisfying each atoms octet rule (haveing 8 electrons in their outer shell), as well as forming a neutral ionic compound.

Californium is a synthetic element and is part of the actinide series in the periodic table, not the lanthanide series. It is located in period 7, group 3, and has the atomic number 98. Californium is a highly radioactive element that is produced in nuclear reactors or particle accelerators.

The vertical grooves in a column are called fluting. They are decorative channels or furrows typically found running vertically along the shaft of a column.

Elements in the same family of the periodic table have similar bonding properties because they have the same number of valence electrons. This results in similar chemical reactivity as they tend to gain, lose, or share electrons in a similar manner to achieve a stable electron configuration. The shared valence electron configuration leads to similarities in their bonding behavior.

Yes, flerovium is a synthetic element that is expected to be a solid at room temperature. However, due to its extremely short half-life (less than a second), it has not been possible to determine its physical state under ordinary conditions.

Sodium hydroxide is a base and hydrochloric acid is an acid. Both are not same.

It is because when you move down, the number of electrons increases. When the number of electrons increases, it calls for more energy levels to fit these electrons.
With each additional period, an additional energy level is occupied. This additional energy level is farther from the nucleus than the previous energy level, so the atoms increase in size.

Democritus, an ancient Greek philosopher, is known for developing the concept of atomism, which suggests that all matter is made up of indivisible particles called atoms. He also proposed that the universe is infinite and that different combinations of atoms create different substances.

The chemical symbol for mercury is Hg. The atomic number for the element is 80. It is one of the only liquid elements on the table.

The element titanium is sometimes referred to as the "wonder element" due to its unique combination of strength, lightness, and resistance to corrosion. It is widely used in aerospace, medical implants, and other high-performance applications.

Te is the symbol for the element Tellurium

Well, for one, they have the same amount of electrons in the outmost shell: Group 1 has 1, Group 2 has 2 etc... They all share similar chemical properties, for example Group 6 (?) S and Se both are acidic oxides.

The intrinsic properties of calcium include its atomic number (20) and its position in the periodic table. Extrinsic properties of calcium can include its physical state (solid at room temperature), its role in bone formation, and its use in various industrial applications.

The basic structure of the periodic table, arranged by increasing atomic number and properties, is unlikely to change significantly in the future. However, as new elements are discovered and our understanding of atomic structure advances, the periodic table may be expanded or refined to accommodate these changes.

Dmitri Mendeleev left blank spaces on the periodic table to account for elements that had not been discovered yet. He predicted the existence and properties of these missing elements based on the patterns and trends of the known elements in the table. This allowed for the successful prediction of the characteristics of elements like gallium and germanium.

Yes, in Microsoft Access, table names can contain digits as long as the name starts with a letter and does not exceed 64 characters in length. It is generally recommended to avoid using digits at the start of the table names for better compatibility and readability.

The first to approach a member of an opposing group is often someone perceived as having higher status or authority within their own group. This individual is usually responsible for initiating contact and representing their group during the interaction.

The first periodic table arranged by atomic mass was created by Dmitri Mendeleev in 1869. Mendeleev's periodic table organized elements by increasing atomic mass and grouped them based on similar chemical properties.
