How do you find out how many electrons are in an outer energy level?
You can determine the number of electrons in the outer energy level of an atom by looking at its group number on the periodic table. For main group elements, the group number corresponds to the number of valence electrons. For example, group 1 elements have 1 valence electron, group 2 elements have 2 valence electrons, and so on.
How many electrons are in oxygen's outer level?
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
What elements have 10 electrons in their outer level?
Elements with 10 electrons in their outer level belong to the group of elements known as the noble gases and the transition metals. Specifically, neon (Ne) is a noble gas with a complete outer shell of 10 electrons. Additionally, transition metals such as chromium (Cr) and copper (Cu) can have 10 electrons in their d-orbitals when considering their electron configurations. However, in terms of main group elements, neon is the most straightforward answer.
Elements with one to two electrons in the outer energy level?
Elements with one to two electrons in the outer energy level are typically the alkali metals (group 1) and alkaline earth metals (group 2) on the periodic table. These elements are highly reactive due to their tendency to lose these outer electrons to achieve a stable electron configuration. Examples include lithium, sodium, and beryllium.
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
What group of elements has a staple number of electrons in their outer energy level?
Group 18 elements have a stable octet.
What is the group of elements with two electrons in the outer level?
alkaline earth metals
What group of elements has a stable amount of electrons in their outer level?
noble gases

How many outer electrons are in Sr?
There are two outer electrons in strontium (Sr) since it belongs to Group 2 of the periodic table. Group 2 elements have 2 electrons in their outer energy level.
How many electrons are in oxygen's outer level?
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
What has 7 electrons in their outer energy level?
Atoms of elements in Group 7A of the periodic table, also known as Group 17 or the halogens, have 7 electrons in their outer energy level. Examples of elements in this group include fluorine, chlorine, bromine, iodine, and astatine.
What is the groups number for elements that have a stable number of electrons in their outer energy level?
Group 8
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.
How many electrons do beryllium and magnesium have in there outer energy levels?
Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
A family of elements that has two electrons in its outer energy level is?
The family of elements with two electrons in its outer energy level is the alkaline earth metals. This group includes elements like beryllium, magnesium, calcium, strontium, and barium. These elements are highly reactive and tend to form 2+ cations by losing their two outer electrons.
