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 the total number of valence electrons in an atom of nitrogen in the ground state?
A fluorine atom in the ground state has 7 valence electrons.
What is the total number of valence electrons in a fluorine atom you n the ground state?
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
When a calcium atom loses its valence electrons the ion formed has an electron configuration that is the same as an atom of?
Argon. Calcium has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2, and when it loses its valence electrons (the outermost 4s2 electrons) it has a configuration identical to argon. If you don't know about sublevels, then disregard that. Calcium has a configuration of 2-8-8-2, and when it loses its 2 valence electrons, it has a configuration identical to argon in the ground state. Hope that cleared it up
How many valence electrons are present in an atom of bromine in the ground state?
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons

What is the number of valence electrons in an atom of Boron in the ground state?
The total number of valence electrons in Boron's ground state is 2
What is the total number of valence electrons in an atom of nitrogen in the ground state?
A fluorine atom in the ground state has 7 valence electrons.
How is an element's most likely oxidation state related to its valence electrons?
It indicates how many electrons are required to complete a full valence shell.
What is the number of electrons in the valence shell of an atom of aluminum in the ground state?
2 valence electrons are in an aluminum atom in the ground state.

Are electron shells and valence electrons the same thing?
Valency is the number of electrons in the outer shell the charge is how many electrons is needed to form an octet (full valence = 8 electrons) Eg. Sulfur valence = 6 charge = -2 (needs to gain 2 electrons to gain an octet)
What is the total number of valence electrons in an atom of carbon in the grounds state?
2s2 2p2
How much valence electrons Ne have?
8 valence electrons (so do all of the other noble gases)
What is the total number of electrons found in the valence shell of an alkaline element in the ground state?
244 An interesting answer...I would have thought that they all have 2 electrons in the outer shell in their ground state.
