What else can I help you with?
Why are no two emission spectra for different elements ever the same?
Because emission spectrum are the result of the electron configuration of the element and no two elements have exactly the same electron configuration.
Which group will have an electron configuration that ends in s2?
Elements in Group 2 of the periodic table will have an electron configuration that ends in s2. This group includes elements such as beryllium, magnesium, and calcium. They have two electrons in their outermost s sublevel.
Does Na or Cl receive or donate an electron?
Sodium (Na) donates an electron, while chlorine (Cl) receives an electron. Sodium has one electron in its outermost shell, which it readily loses to achieve a stable electronic configuration. In contrast, chlorine has seven electrons in its outer shell and needs one more to complete it, making it inclined to accept an electron. This transfer of electrons facilitates the formation of ionic bonds between these two elements.
Are group one or group two more reactive?
Group one elements are generally more reactive than group two elements. This is because group one elements have one electron in their outermost shell, making them more willing to react and form compounds in order to achieve a stable electron configuration. Group two elements have two electrons in their outermost shell, which makes them less reactive than group one elements.
Two elements that have atoms of verry diffrent sizes means that the cast iorn is likely what?
Two elements that have atoms of very different sizes means that the cast iron is likely a substitutional alloy.
What two elements other than chlorine that are likely to accept an electron from sodium?
Fluorine and oxygen are two elements that are likely to accept an electron from sodium, forming ions in the process.
Which of the following elements sodium oxygen chlorine and aluminium will give out electrons and how many electrons will it accept?
Sodium lose one electron, aluminium lose three electrons.Chlorine accept one electron, oxygen accept two electrons.
Would type of bond would magiusum make?
Magnesium typically forms ionic bonds, where it donates two electrons to another atom to achieve a stable octet electron configuration. This makes magnesium likely to bond with elements that can easily accept its two electrons, such as oxygen in the formation of magnesium oxide.
Is a ionic compound likely to form between fluorine and lithium?
Yes, an ionic compound is likely to form between fluorine and lithium. Fluorine, being a highly electronegative element, will readily accept an electron from lithium, which is a metal with low electronegativity. This transfer of electrons will result in the formation of an ionic bond between the two elements.
Why are no two emission spectra for different elements ever the same?
Because emission spectrum are the result of the electron configuration of the element and no two elements have exactly the same electron configuration.
Why only 12 elements form ions easier than the rest of the elements in periodic table?
I would imagine that these elements are hydrogen, the alkali metals and the halogens. Hydrogen and the alkali metals only have one outer electron, which is easier to displace than the two outer electrons of the alkaline earth metals, for example. In contrast, the halogens only need one more electron to have a complete outer shell; it is easier to accept one electron than the two electrons needed by the chalcogens - oxygen, sulphur, selenium etc.
If the first energy level is complete with two electrons then what has two elements?
If the first energy level is complete with two electrons, then the elements hydrogen and helium have two elements in their electron configuration. Hydrogen has one electron in its first energy level, while helium has two electrons filling its first energy level.
What two entities are formed when one element transfers an electron to a different element which can accept the electron?
A positive ion ( the one that gives the electron) and a negative ion ( the one that accepts).
What elements contains the same inside electron arrangement as phosphorus?
Two identical electron configuration doen't exist for atoms.
Elements contains the same inside electron arrangement as phosphorus?
Two identical electron configuration doen't exist for atoms.
How do elements achieve stable electron configurations between two atoms?
protons
Covalent bonds form between what two types of elements?
Covalent bonds form between nonmetal elements. These elements share electrons to achieve a stable electron configuration and create a bond by overlapping their electron clouds.
