Mendeleev was the inventor of the Periodic Table. He organized all the known elements into the periodic table based on atomic number. He was also able to predict the existence of elements that had not yet been discovered based on gaps in the table he created. Based on observations of other elements in the groups he was also able to predict the characteristics of these unknown elements as well. NICE! dude
The NFL mock draft is when football analysts try to predict what teams will draft which players based on what that teams needs to improve with
It's based on the location of top colleges.
The element gallium, discovered in 1875, empirically supported Mendeleev's periodic table by fitting into the predicted gaps in the table based on its properties.
No, the belief that the world would end in 2012 was based on a misinterpretation of the Mayan calendar. The Mayans did not predict an apocalypse, but rather their calendar simply marked the end of one cycle and the beginning of another. Therefore, the world was not meant to end in 2012.
Yes, it is possible - the electron configuration is a specific characteristic.
Yes, it is possible - the electron configuration is a specific characteristic.
An element's electron configuration determines its chemical properties, which in turn influence its placement on the periodic table. Elements with similar electron configurations tend to exhibit similar chemical behavior and are grouped together on the periodic table in columns (groups). The periodic table is organized based on similarities in electron configurations to help predict an element's properties based on its location.
It can't. the properties of an element determine it's group placement, without knowledge of these properties (or, indeed, the element itself) it would be impossible to place an element in it's proper place on the periodic table.
The element with the electron configuration 2s1 is lithium (Li). However, there is no element with the electron configuration S2d1 as "S" and "d" are not valid subshells in the electron configuration notation based on the periodic table.

The location of an element on the periodic table is determined by its atomic number, which in turn dictates its placement based on electron configuration and chemical properties. The element's position on the periodic table can provide information about its characteristics and reactivity with other elements.
To predict an element's oxidation number, you can use the rules based on the periodic table and chemical bonding principles. For example, in many cases, elements prefer to have a full valence shell, so they will gain or lose electrons to achieve that stable electron configuration. Additionally, the group number of an element can provide a general idea of its typical oxidation number.
Yes, the Aufbau principle applies to all elements. It states that electrons fill orbitals starting with the lowest energy levels before moving to higher energy levels. This principle helps to predict the electron configuration of elements based on the periodic table.
Yes, but an electron configuration could be that of an ion. The identification of an element depends on the number of protons in its nucleus, so only when the species is also neutral can the electron configuration be used to identify it. Examples 1s2 2s2 2p6 is the electron configuration of Neon but also of F-. Take the superscripts and add them together to get the atomic number and if neutral must be Neon but if negative is that of F-
The arrangement of the periodic table helped scientists predict the properties of missing elements based on their location in the table. For example, when Dmitri Mendeleev noticed gaps in the periodic table, he was able to predict the properties of the missing elements based on the neighboring elements, which ultimately led to the discovery of new elements like gallium and germanium.
The electron configuration provided seems to be incorrect. The correct electron configuration for an element is based on the Aufbau principle, which governs the way electrons fill energy levels and sublevels. Double-check the electron configuration using the correct order of filling for orbitals.
