What does a group 17 atom need to reach a stable electron configuration?

What does a group 17 atom need to reach a stable electron configuration?

Elements in group 1 need to lose one electron to achieve a stable electron configuration. Elements in groups 14 and 17 need to gain four and one electrons, respectively, to achieve a stable configuration.

How many electrons does group 16 lose?

two electrons
Atoms of group 17 gain one electron and form anions with a 1− charge; atoms of group 16 gain two electrons and form ions with a 2− charge, and so on.

How many electrons are involved when P form a bond?

Luckily, every phosphorus atom is looking to gain three electrons. It’s a perfect match! Something to notice though, look how they have a bond with six electrons. That bond is known as a triple bond.

How many electrons do elements in Groups 14 and 17 need to gain to achieve a stable configuration?

four
Elements in groups 14 and 17 need to gain four and one electrons, respectively, to achieve a stable configuration. Understanding that the organization of the periodic table is based on the total number of protons (and electrons) helps us know how electrons are distributed among the outer shell.

How many electrons does Group 14 lose?

Elements in Group 14 could lose four, or gain four electrons to achieve a noble gas structure. In fact, if they are going to form ions, Group 14 elements form positive ions.

How many electrons are in the outer most shell of an atom with 17 electrons?

seven electrons
Fluorine (F) and chlorine (Cl), as group 17 elements, have seven electrons in their outermost shells. They tend to achieve a stable octet by taking an electron from other atoms, becoming negatively charged ions: F− and Cl−. Carbon (C), as a group 14 element, has four electrons in its outer shell.

How many electrons are in the outermost shell of an atom with 15 electrons?

So according to the electron configuration, there are 5 electrons in the valence shell.
