All of the representative elements (s and p block) have predictable electron configurations. However, many of the transition elements have electron configurations that are not predicted by the rules for determining electron configuration.
Noble gas notation is a way of simplifying electron configurations by using the previous noble gas's electron configuration as a starting point. For calcium, the electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2. Using the noble gas argon (1s2 2s2 2p6 3s2 3p6) as the starting point, the noble gas notation for calcium is [Ar] 4s2.
The electron configurations of LiF will be the same as the electron configurations of atoms in Group 18 (noble gases) because Li will lose its single electron to attain a stable octet similar to the noble gases, while F will gain an electron to achieve a complete valence shell.
When calcium reacts with chlorine, they form calcium chloride, a white crystalline solid compound. This reaction is typically highly exothermic and releases a large amount of heat. The reaction proceeds with the calcium atoms losing two electrons and the chlorine atoms gaining one electron to achieve stable electron configurations.
Yes, understanding the electron configurations of elements can help explain the arrangement of elements on the periodic table. Electron configurations determine an element's chemical properties, reactivity, and position within the table. The periodic table is organized based on recurring patterns in electron configurations, such as the filling of energy levels and sublevels.
Solutions are mixtures of one or more solutes dissolved in a solvent. They do not have electron configurations. Only atoms and ions have electron configurations.
No, calcium (Ca) has a unique electron configuration due to its atomic number and position in the periodic table. Its electron arrangement is 1s2 2s2 2p6 3s2 3p6 4s2. While there are other elements with similar electron configurations, none are identical to calcium.

You don't. Calcium is not an electron, calcium is a element

any time there are as many electrons and protons and they fill each orbital optimally.
The externall shell of electrons is completely filled.
Yes, understanding the electron configurations of elements can help explain the arrangement of elements on the periodic table. Electron configurations determine an element's chemical properties, reactivity, and position within the table. The periodic table is organized based on recurring patterns in electron configurations, such as the filling of energy levels and sublevels.
The element calcium, or Ca, is located in group 2, period 4 of the Periodic Table. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. This can also be written as [Ar] 4s2, because the beginning of that electron configuration is the same as argon's. The 42 you mentioned in your question is referring to a specific isotope of calcium and has nothing to with the electron configuration.
Stable electron configurations are most likely to contain filled energy levels or filled subshells. These configurations generally follow the octet rule or duet rule, depending on the element. Additionally, stable electron configurations may contain configurations with a full valence shell of electrons.
