The number of electrons in the outer energy level of Group 17 elements is?
Group 17 elements, also known as the halogens, have seven electrons in their outer energy level. This makes them highly reactive, as they only need one more electron to achieve a stable octet configuration.
Fluorine and chlorine have similar?
chemical properties due to their location in the same group (Group 17) of the periodic table. Both elements have seven valence electrons and tend to form similar types of compounds. Additionally, they are both highly reactive nonmetals.
How many valence electrons do Halogens have?
The number of electrons are different from one to another, however all of them have seven electrons in the valence shell.
How many more valance electrons does oxygen need to have a full outer valence shell?
None. Neon is a noble gas, a category of elements that exist in nature as inert gasses. In special situations, neon can be made to react with other elements, but in ordinary conditions, neon is inert, which just means non-reactive. It's outer orbit is full--it doesn't want to give up the electrons it has, or to take any more.
What do bromine and chlorine have in common?
The atoms of both elements have seven valence electrons and a strong tendency to abstract, from a less electronegative atom, an electron to complete their valence shells and thereby become an anion.
What elements have seven valence electrons?
The halogens, or group 17
Which electron has seven valence electrons?
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
How can i look at the periodic table and tell how many valence electrons an element has?
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
The most reactive elements have how many valence electrons?
The most reactive elements require to lose or gain the least number electron(s) to attain a noble gas structure. These are elements in group one as they need to lose one electron, and elements in group seven as they need to gain one electron.
What is the number of electrons needed for stability in the groups of the periodic table?
They r noble gases which have stable valance shell and grotp no. 18
Why do the elements in the vertical columns all have the same chemical properties?
Group 1 have one valence electron. The elements in Group 2 have two. The elements in Group 17 have seven valence electrons, and Group 18 elements have eight. Because the valence electrons within a family are the same, the elements in that group have similar properties.
The number of electrons in the outer energy level of Group 17 elements is?
Group 17 elements, also known as the halogens, have seven electrons in their outer energy level. This makes them highly reactive, as they only need one more electron to achieve a stable octet configuration.
What elements have seven valance electrons?
Elements that have seven valence electrons include the halogens in Group 17 of the periodic table, such as fluorine, chlorine, bromine, and iodine. These elements are highly reactive due to their tendency to gain one electron to achieve a full valence shell.
What atoms have seven electrons in their outermost energy levels?
All halogens (fluorine, chlorine, bromine, iodine and astatine) have 7 valence electrons.
What are the elements with seven valence electrons?
halogens such as flourine, chlorine, bromine..
Which atoms are most reactive?
The most reactive elements have either 1 valence electron or 7 valence electrons
What group of elements with seven electrons in the outer level?
halogens (group 17 elements)
