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.

How many electons does neon have?
Neon has two rings. It also has eight electrons in its outer energy level.
How many more electrons does phosphorus have than boron?
Phosphorus has 10 more electrons. A neutral atom of phosphorus has 15 electrons, 3 in the outer 3p shell There are 5 electrons in a neutral atom of boron, 1 in the outer 2p shell.
How is the radius of an atom related to the atoms attraction for outer level electrons?
As the radius of an atom increases, the attraction between the positively charged nucleus and the negatively charged outer level electrons decreases. This is because the outer level electrons are farther away from the "home base." So, as atomic size (radius) increases, the nucleus has less and less a hold on those outermost electrons. For this reason, cesium (Cs, atomic #55) has very large atomic size and very low electronegativity. Fluorine (F, atomic #9) has very small atomic size but large electronegativity.
Which element have 10 electrons and 10 neutrons?
The element with 10 electrons and 10 neutrons is Neon. Neon has the atomic number 10, which corresponds to the number of electrons in a neutral atom, and its most common stable isotope has 10 neutrons.
Is the outer shell of nickel full?
The outer shell of nickel is not full. Nickel has an electron configuration of 4s2 3d8, so its outer shell has two electrons which is not the maximum it can hold (which would be 8).
How many electrons in zinc outer level?
10 electrons
What elements don't have 8 electrons?
Elements with atomic numbers higher than 10 generally do not have 8 electrons in their outermost energy level. These elements tend to follow the octet rule, where they aim to have 8 electrons in their outer shell to achieve stability. Exceptions include elements such as transition metals that can have variable oxidation states.
How many electrons occur in the valence level of Group 7A and 7B elements. Why are they different?
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
How many outer-shell electrons does sulfur have?
Sulfur has 6 outer shell electrons, as do all other atoms in column 16 of a wide form Periodic Table, in the usual chemical meaning. A physicist, especially a spectroscopist, might well consider only the 3p electrons of sulfur the outer shell, since the 3s electrons have a detectably lower energy level. On that view, sulfur would contain 4 outer shell electrons.
How many electrons fill up an outer shell?
The number of electrons depends on the element and it may vary from 1 to 2 (for s block elements), 3 to 8 (for p block elements), 1 to 10 for d block elements and 1 to 14 (fro f block elements).
How many electrons are in the second energy level of neon?
Neon is a noble gas, therefore it is stable meaning that its outer energy ring is full. It has 8 elections on its outer energy level. Check out the related link for a picture of a model of Neons atom.
How many elements can the 3rd shell hold?
The 3rd shell can contain 18 electrons. The elements that have a 3rd shell as the outer shell are the the elements in period 3, where the 3s and 3p orbitals are filled to a maximum of 8 electrons. The 3d orbitals are filled in the 4th period in the transition elements.
How many electrons are there in the outer shell of a neutral neon atom?
A neutral neon atom has 8 electrons in its outer shell. Neon has a total of 10 electrons, with 2 in the inner shell and 8 in the outer shell.
Atom whose atomic number is 10 has how many electrons in its outermost energy level?
An atom with an atomic number of 10 (neon) has 8 electrons in its outermost energy level. This is because it follows the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.
Why are Neon and Argon such nonreactive elements in the periodic table?
Neon (atomic number 10) and Argon (atomic number 18) mostly do not react with other elements because their outermost electron shells have a full complement of electrons. When two elements combine into a molecule they share electrons from their outermost electron shell. This happens when one element has a minimal number of electrons in its outer shell and the other element has an almost full complement of electrons in its outer shell. When they share electrons, they both have the equivalent of full outer electron shells. Since both Neon and Argon have full outermost shells by themselves they do not have a tendency to share electrons.
What is the electron arrangement for neon?
The electron configuration of neon is [He]2s2.2p6.
How many electrons does neon have in the third energy level?
Neon's complete electron configuration is: 1s22s22p6 Therefore, normally, neon does not have any electrons in its third energy level. As you can see, neon is a noble gas with 8 electrons in its valance shell, and is therefore chemically stable and is unlikely to react.
