What group has the octet on the periodic table?
The noble gases usually have an octet on the periodic table. They have a full outer shell of electrons, making them stable and unreactive.
Element x is in gropu 2 and element y is in group 17 what happens when a compound is formed between these two atoms?
When a compound is formed between an element from group 2 (such as x) and an element from group 17 (such as y), they will likely combine in a 1:2 ratio to form an ionic compound. The Group 2 element will lose 2 electrons to achieve a stable octet, becoming a 2+ cation, while the Group 17 element will gain 1 electron to achieve a stable octet, becoming a 1- anion. This results in the formation of a compound with a 1:2 ratio of cations to anions.
What group has a complete octet and wont bond with other atoms?
Noble gases have a complete octet and are stable because they have a full outer electron shell. They do not chemically bond with other atoms because they are already in a stable configuration.
Which main-group elements occasionally break the octet rule?
Main-group elements such as boron, beryllium, and sulfur can occasionally break the octet rule by having fewer or more than eight valence electrons in their outermost shell. Boron and beryllium are known to form stable compounds with only six or even four electrons in their valence shell, while sulfur can expand its octet to accommodate more than eight electrons.
What is the charge of group 6a in the periodic table?
The elements of group VI A require two electrons to complete the octet so they mostly form -2 ions as O-2, S-2
