Why does group 1 elements prefer to combine with group 17 elements?
Group 1 elements (alkali metals) prefer to combine with Group 17 elements (halogens) because alkali metals have one electron in their outer shell, which they can easily donate to achieve a stable electron configuration. Halogens, on the other hand, have seven electrons in their outer shell and can easily accept an electron to achieve a stable electron configuration. This electron transfer results in the formation of ionic compounds between alkali metals and halogens.
Why alkaline and halogens are so reactive?
Alkaline and halogens are reactive because usually they are attracted to each other. Why? Because halogens have seven valence electrons, or electrons in their outermost shell, while alkaline metals only have one valence electron. An example of a halogen is florine and chlorine. An alkaline metal example is hydrogen and lithium.
Why halogens have highest negative electron gain enthalpy?
Good question. Halogens have their outer electronic configuration as ns2np5 and require only one more electron to gain a stable electronic configuration. So they have a great affinity for electrons and will accept them very easily by releasing energy. So they have the highest electron gain enthalpy.
How many electrons does silver have to gave up in order to achieve a pseudo-noble-gas electron configuration?
Silver (Ag) has 47 electrons. To achieve a pseudo-noble-gas electron configuration, silver would need to lose one electron to achieve a stable electron configuration that resembles a noble gas configuration like argon.
Which elements have electron configurations that end in ns2np5?
The elements with electron configurations ending in ns2np5 are the halogens in Group 17 of the periodic table. This includes fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). These elements have seven valence electrons and readily gain an electron to achieve a stable octet configuration.
What group achieves the electron configuration of a noble gas by gaining one electron?
All halogens have 7 valence electrons. They gain one electron and achieve noble gas electronic configuration
Why do halogens gain electrons?
Halogens have 7 valence electrons, in order to become a noble gas you need 8 so instead of losing electrons, it would be easier just to gain 1. That would make Halogens a negative 1 If you do the dot structure you can see that there is only room to gain 1 electron when forming a bond.
What is characteristic about the outer electron shells of the halogens?
The outer electron shells of the halogens typically contain seven electrons, making them highly reactive and likely to gain one electron to achieve a stable electron configuration. Additionally, halogens have a tendency to form negatively charged ions when they react with other elements by gaining one electron.
What is the characteristics about the outer electron shells of halogens?
The outer electron shells of halogens have seven electrons, making them one electron short of a full outer shell. This makes halogens highly reactive as they tend to gain an electron to achieve a stable electron configuration. Halogens are located in Group 17 of the periodic table.
Why are halogens oxidising agents?
Halogens are strong oxidizing agents because they have a high electron affinity and can easily accept electrons from other atoms or ions, causing them to be reduced in the process. They have a high tendency to gain electrons to achieve a stable electron configuration, making them effective at oxidizing other substances by removing their electrons.
What type of bonding do group 7 elements form with metals?
Group 7 elements, also known as the halogens, typically form ionic bonds with metals when they react. Halogens have a strong tendency to gain an electron to achieve a stable electron configuration, while metals tend to lose electrons to achieve the same stability. This transfer of electrons results in the formation of ionic compounds between the halogens and metals.
Why does group 1 elements prefer to combine with group 17 elements?
Group 1 elements (alkali metals) prefer to combine with Group 17 elements (halogens) because alkali metals have one electron in their outer shell, which they can easily donate to achieve a stable electron configuration.

How many electrons must be gained or lost for Iodine to achieve a noble gas electron configuration?
Iodine, located in Group 17 of the periodic table, has 7 valence electrons. To achieve a noble gas electron configuration (like Xenon), it must gain 1 electron to fill its valence shell and attain stability.
Why halogens have highest negative electron gain enthalpy?
Good question. Halogens have their outer electronic configuration as ns2np5 and require only one more electron to gain a stable electronic configuration. So they have a great affinity for electrons and will accept them very easily by releasing energy. So they have the highest electron gain enthalpy.
How many electrons must be gained or lost for selenium to achieve a noble gas electron configuration?
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
Which class of nonmetals is the most reactive?
The halogens are the most reactive class of nonmetals due to their high electronegativity and tendency to gain electrons to achieve a stable electron configuration. This results in them readily forming compounds with other elements.
