Which elements have electron configuration that end in ns2 np5?
The elements with electron configurations ending in ns2 np5 are the halogens in group 17 of the periodic table: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
How many electrons do the elements in Group11A2 of the periodic table have in their electron dot diagrams?
Elements in Group 11 (coinage metals) of the periodic table, such as copper, silver, and gold, have 1 electron in their outer shell. This results in electron dot diagrams where they have one dot represented around the element's chemical symbol.
What group in the periodic table releases the most energy by gaining an electron?
The halogen group in the periodic table releases the most energy by gaining an electron because they have a high electron affinity and tend to form stable, energy-releasing compounds when they gain an electron to achieve a full outer electron shell.
How many electrons do halogens have to lose or gain to achieve a stable noble gas electron configuration?
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.
What is the name in the column of the periodic table next to the nobel gases Why are they so reactive?
The column next to the noble gases in the periodic table is the halogens group. Halogens are highly reactive because they only need one more electron to complete their outer electron shell and achieve a stable electron configuration. This makes them eager to chemically react with other elements to gain that electron and become stable.
Which group on the periodic table will gain an electron in reaction?
group 17 - the halogens
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.
What group of the periodic table most readily accepts electron?
Group VII A or XVII or Halogens.
In the periodic table that included electron dot diagrams in which column would the diagrams contain more dots group A the alkaline metals or group A the oxygen family?
In the periodic table, group A refers to the main groups, including the alkaline metals (group 1) and the oxygen family (group 16). The electron dot diagrams for the alkaline metals would contain one dot, as they have one valence electron. In contrast, the oxygen family elements have six valence electrons, resulting in their electron dot diagrams containing six dots. Therefore, the diagrams for the oxygen family would contain more dots than those for the alkaline metals.
Which elements have electron configuration that end in ns2 np5?
The elements with electron configurations ending in ns2 np5 are the halogens in group 17 of the periodic table: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
How many electrons do the elements in Group11A2 of the periodic table have in their electron dot diagrams?
Elements in Group 11 (coinage metals) of the periodic table, such as copper, silver, and gold, have 1 electron in their outer shell. This results in electron dot diagrams where they have one dot represented around the element's chemical symbol.
Where on the periodic table would you find the halogens?
The halogens can be found in Group 17 (Group VIIA) on the periodic table. They include elements such as fluorine, chlorine, bromine, iodine, and astatine. These elements have similar chemical properties due to their outer electron configuration.
What group in the periodic table releases the most energy by gaining an electron?
The halogen group in the periodic table releases the most energy by gaining an electron because they have a high electron affinity and tend to form stable, energy-releasing compounds when they gain an electron to achieve a full outer electron shell.

Differences between alkil metals and halogens?
The elements of the 1st GROUP of the periodic table are called alkali metals. The elements of the 17th GROUP of the periodic table are called halogens. Alkali metals are soft metals whereas halogens are non-metals.
What was the most active nonmetal?
Halides are the most active nonmetals on the periodic table because it has high electronegativity. Meaning it is more likely to attract an electron towards itself to react.
