transition metals
A gas is a state of matter characterized by particles that are widely spaced out with no definite shape or volume. Gas molecules move freely and quickly, filling any container they are placed in. Examples include oxygen, nitrogen, and carbon dioxide.
The outermost energy level of carbon-13 contains 3 electrons. This is because carbon-13 has 6 electrons in total, with 2 of them filling the first energy level and the remaining 4 in the second energy level.
Atoms can give away electrons to achieve a stable configuration by filling their outermost energy levels. This can happen when an atom has excess electrons or when it is more stable when losing electrons to achieve a full outer shell. This exchange of electrons helps atoms achieve a more stable state through the formation of bonds.
The filling pressure in an LPG cylinder refers to the amount of pressure at which the cylinder is filled with liquefied petroleum gas. This pressure can vary depending on factors such as the type of gas being used and the ambient temperature. Typically, the filling pressure for LPG cylinders ranges from 2 to 10 bar.
The lanthanides and actinides are known as the inner transition metals. They are located at the bottom of the periodic table and have electron configurations that include f-orbitals. They share similar chemical properties due to the filling of their f-orbitals.
They are called transition elements or transition metals. These elements have partially filled d or f orbitals, which lead to unique properties such as variable oxidation states and the ability to form colored compounds.
Transition elements are called transition elements because the electrons in these elements are not in process of filling valence(outermost ) shell instead they are, in case of d-block elements, in process of filling penultimate shell. and in case of f- block elements, electrons are in process of filling next to the penultimate shell.
The s, p, d, f block realte to the filling of the outer shell orbitals. Group 1 and 2 are the s block. Groups 13-18 the p block, the transition metals the d block and the lanthanides and actinides the f block.
Elements in the zinc group of the periodic table, such as zinc (Zn) and cadmium (Cd), have the electron configuration s2d10 in their outermost shell. This configuration results from the filling of the 3d orbital after the 4s orbital is filled.
The Periodic Table is organized in rows and columns called Periods and Groups respectively. Each row (period) in the table corresponds to the filling of a quantum shell of electrons. The elements in a group have similar configurations of the outermost electron shells of their atoms: as most chemical properties are dominated by the orbital location of the outermost electron. See http://knol.google.com/k/spiros-kakos/periodic-table-of-elements/2jszrulazj6wq/88# for more details on the meaning of groups and periods.
the d subshells
They relate to the sub orbital type, or the highest energy orbitals that are occupied in a given element that falls under the subsequent block of the periodic table. Plato: Its not D. none of the above
The outermost electrons of vanadium are located in the 4s and 3d orbitals. These electrons generally occupy the 4s orbital before filling the 3d orbitals.
The elements on the right side of the periodic table with electrons sequentially filling orbitals in their valence are known as the "p-block elements". These elements include groups 13 to 18 on the periodic table.
According to Kaplan, an MCAT prep course, Group O elements are also known as noble, rare, or inert gases. If you, on the off-chance, have access to the study books, I am getting this from Chapter 2, page 29 of the gen chem review book. Good luck.
Lanthanides are called inner transition elements because they fill the 4f orbitals, which are part of the inner electron shell transition metals. These elements are also characterized by the gradual filling of the 4f subshell across the lanthanide series.
The series of ten elements filling the 3d sublevel is called the transition metals. These elements are known for their ability to form multiple oxidation states and their characteristic colored compounds.
