What element has a electron of 85?
The element with the atomic number 85 is Astatine (At). Astatine is a Radioactive Halogen in Group 17(7) of the Periodic Table. Astatine has 85 electrons in 6 shells with 7 electrons in the outer shell. Astatine is the third radioactive element on the Periodic Table.
What group does group one from the periodic table likes to reacts with?
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
How many outer shell electron does an atom of an element belonging to the halogen family have?
An atom of an element belonging to the halogen family typically has 7 outer shell electrons. Halogens are in group 17 of the periodic table, which means they have 7 valence electrons.

An atom of an element belonging to the halogen family typically has 7 outer shell electrons. Halogens are in group 17 of the periodic table, which means they have 7 valence electrons.
What is a neutral atom that has its first two shells filled has 7 electrons on the third energy level and has no other electrons?
The first electron ring is filled with 2 electrons. The next is filled with 8. So an element with the first two rings filled and 7 electrons in the third would have a total of 17 electrons. (NOTE: The term shell isn't exactly right, since in nuclear physics, each "shell" only holds 2 electrons, and they are all filled in a certain order based on energy levels. This is more complex than the simple high school chemistry model of rings, though, and your question seems to be asking about the rings due to the "7 on the third energy level" part.) For it to be neutral, it will have the same number of protons as electrons, 17. The first 2 are the top row, Hydrogen and Helium. The next 8 are the second row. So if we go 7 across (left to right) on the third row, we get to CL. The element you're asking about is Chlorine.
How many element do the elements belonging two group IIIA have in there outermost shell?
Elements in group IIIA, also known as group 13, have 3 electrons in their outermost shell. This is because they are located in the third column of the periodic table, which determines the number of valence electrons an element has based on its group number.
How many protons does chlorine have in their inside thes hell?
There are 17 altogether . . . The first shell has 2 The second shell has . . . 8 And the third shell has . . . 7 I hope this has helped :) x
How many electrons are in the third ring of the atom Chlorine?
The third electron shell of an atom, also known as the third energy level, can hold a maximum of 18 electrons. Chlorine has 17 electrons, so in the third shell, there would be 7 electrons (17 total electrons - 2 in the first shell - 8 in the second shell = 7 in the third shell).
