8 electrons. Can be found from the formula 2n2. Where n=the number of the energy level. The number of electrons in the second shell is very important to remember however, because it provides for the octet rule of bonding that almost all elements conform to. Elements wish to have 8 electrons in their outer shell, making the Noble Gases unreactive, and providing for the charges, or oxidation states, of all elements that determine how they bond. Davey.

What is an element whose atoms contain 4 electrons in the second energy level?
Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.
What atoms contain exactly two unpaired electrons?
Oxygen atoms contain exactly two unpaired electrons. This is because oxygen has 6 total electrons, with 2 in the first energy level and 4 in the second. Two of the electrons in the second energy level are unpaired.
What is the total number of electrons needed to completely fill all of the orbitals in an atoms second principal energy level?
The second principal energy level can hold a maximum of 8 electrons in total. This is because the second level consists of one s orbital and three p orbitals, which can hold 2 electrons each.
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 do silicon atoms have?
14 electrons. 2 electrons in the first shell, 8 electrons in second shell, and 4 electrons in the valence shell.
An atoms second energy level can hold up to how many electrons?
Maximum of 8 electrons in second energy level.
How many electrons can an atoms second energy level hold?
8
How many electrons does calcium have in the second energy level?
Calcium atoms have 8 electrons in the second energy level. However, they are not the valence electrons. The outermost electrons in a calcium atom in the ground state are 2 4s electrons. So calcium atoms in the ground state have 2 valence electrons in the fourth energy level.
What is an element whose atoms contain 4 electrons in the second energy level?
Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.
How many d electrons can a second energy level hold?
The second energy level of atoms can hold a maximum of 8 electrons.
What atoms contain exactly two unpaired electrons?
Oxygen atoms contain exactly two unpaired electrons. This is because oxygen has 6 total electrons, with 2 in the first energy level and 4 in the second. Two of the electrons in the second energy level are unpaired.
How many electrons do the caron atoms have?
Carbon atoms have a total of six electrons. In a neutral carbon atom, these electrons are arranged with two in the first energy level (the innermost shell) and four in the second energy level, allowing for the formation of four covalent bonds with other atoms.
How many atoms can he second energy level hold?
2s^2 2p^6 8 electrons total
What is the total number of electrons needed to completely fill all of the orbitals in an atoms second principal energy level?
The second principal energy level can hold a maximum of 8 electrons in total. This is because the second level consists of one s orbital and three p orbitals, which can hold 2 electrons each.
