There are more than two such atoms.
Perhaps there was a list of atoms you had to chose from.
Anyway, two such atoms are beryllium and magnesium.
What else can I help you with?
Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.
How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs two electrons to have a filled outermost energy level.
What is outer energy level is filled with elections?
The outer energy level of an atom is referred to as the valence shell, and it is filled with electrons when it contains the maximum number of electrons allowed, usually eight for most elements (known as the octet rule). This configuration contributes to an atom's stability and chemical behavior. Atoms with filled outer energy levels tend to be less reactive, as they do not seek to gain or lose electrons. Noble gases, such as helium and neon, have completely filled outer energy levels.
Do noble gases have the maximum number of electrons in their outer energy level?
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
How many electrons are in the highest level occupied energy level of these atoms?
8
Which two atoms will have their outer energy level filled with 2 electrons?
Helium (He) and Neon (Ne) will both have their outer energy level filled with 2 electrons.
What two atoms will have their outer energy level filled with two electrons?
Helium and neon will have their outer energy level filled with two electrons. Helium has 2 electrons in its only energy level, while neon has 8 electrons in its second energy level.
How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
What element has atoms with only one completely filled principal energy level?
undiscovered...yet, but there are a few...go forward 50 years and see

How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs two electrons to have a filled outermost energy level.
An atom with an incompletely filled outermost energy level is likely to be?
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because atoms tend to gain, lose, or share electrons to achieve a stable outer electron configuration. Atoms with incomplete outermost energy levels are looking to fill or empty their outermost energy level to achieve stability.

How many electrons does it need to have in the outermost energy level filled?
8 electrons

How many electrons are in the outermost level of carbon how many electron does it need to have fill this energy level?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
What atoms need only 2 valence electrons to have a filled out level?
Helium.
