If the first energy level is complete with two electrons then what has two elements?
If the first energy level is complete with two electrons, then the elements hydrogen and helium have two elements in their electron configuration. Hydrogen has one electron in its first energy level, while helium has two electrons filling its first energy level.
How many electrons are in the highest occupied energy level in Group 8A?
Group 8A elements have 8 valence electrons. This means that the highest occupied energy level in Group 8A elements will have 8 electrons, as the maximum number of electrons in an energy level is 8 based on the octet rule.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
What is the relationship between the ionization energy of s and the reactivity of elements in the periodic table?
The ionization energy of an element's s electrons is related to its reactivity in the periodic table. Elements with low ionization energy tend to be more reactive because they easily lose electrons to form positive ions. Conversely, elements with high ionization energy are less reactive as they require more energy to lose electrons.
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.
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
What stops the flow of electrons in a circuit?
all passive elements which absorb energy from active elements can control the flow of electrons
If the first energy level is complete with two electrons then what has two elements?
If the first energy level is complete with two electrons, then the elements hydrogen and helium have two elements in their electron configuration. Hydrogen has one electron in its first energy level, while helium has two electrons filling its first energy level.
How many electrons are in the highest occupied energy level in Group 8A?

What is the number of electrons in the 1st energy level of magnesium?
All elements except hydrogen have two electrons in the first energy level.
How does the number of the outer energy level electrons relate to the properties of elements?
Elements whose atoms have the same number of outer electrons have similar properties..

Elements whose atoms have the same number of outer electrons have similar properties..
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
Electrons in wich energy level determines the chemical behavior of elements?
the outermost energy level! ( :
Which elements have 3 energy levels with only 4 electrons in the last energy level?
oxygen
What is the relationship between the ionization energy of s and the reactivity of elements in the periodic table?
The ionization energy of an element's s electrons is related to its reactivity in the periodic table. Elements with low ionization energy tend to be more reactive because they easily lose electrons to form positive ions. Conversely, elements with high ionization energy are less reactive as they require more energy to lose electrons.
How do you find valency of elements?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
