What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
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.
In a bromine atom which atomic orbitals contain the valence electrons?
* Ground state electron configuration:[Ar].3d10.4s2.4p6 so...4s and 4p
How many unpaired electrons does phosphorus have in its ground state?
Phosphorus has three unpaired electrons in its ground state.
Does sulfur have electrons in the third energy level?
Sulphur Symbol 'S'. Atomic Number = 16. Atomic weight = 32 Nucleus = 16 Protons & 16 Neutrons. Electrons = 16 in 3 Energy levels Shell 1 or 'K' = 2 electrons Shell 2 or 'L' = 8 Shell 3 or 'M' = 6
The 4d subshell in the ground state of atomic xenon contains electrons?
The 4d subshell in the ground state of atomic xenon contains 10 electrons.
What Element has lowest atomic number that contains a complete d sub shell at ground state?
The element with the lowest atomic number that has a complete d subshell at its ground state is Titanium (element 22). In its ground state, Titanium's electron configuration is [Ar] 3d2 4s2, which means the 3d subshell is completely filled with 2 electrons.
What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?

What element contains 3d6?
Manganese (Mn) contains 3d5 electrons in its ground state electron configuration.
What element of lowest atomic number contains a half filled d subshell at ground state?
The element with the lowest atomic number that contains a half-filled d subshell at its ground state is scandium (atomic number 21). The electron configuration of scandium at ground state is [Ar] 3d^1 4s^2, where the 3d subshell is half-filled with one electron.
How many unpaired electrons are predicted for the ground state configuration of Ta?
For the ground state electron configuration of an element, we look at the filling of orbitals up to that element's atomic number. Tantalum (Ta) has an atomic number of 73, belonging to the transition metals, and has a ground state electron configuration of [Xe] 4f14 5d10 6s2 6p6 6d3 7s2. Counting the number of electrons in the partially filled orbitals (5d and 6d), there are 3 unpaired electrons.
What element has the ground-state electron configuration of Ar4s23d6?
The element with that electron configuration is Iron.
Why is an element's number important?
An elements atomic number is important because it tells you how many protons are in the nucleus of the atom, and how many electrons are orbiting the nucleus in the ground state.
How many electrons in the 3p subshell in the ground state of atomic silicon?
In the ground state of atomic silicon, which has an atomic number of 14, there are a total of 14 electrons. The electron configuration is 1s² 2s² 2p⁶ 3s² 3p². Therefore, there are 2 electrons in the 3p subshell.
Which element has 45 electrons in its ground state?
Rhodium
How many unpaired electrons are there in stadium?
Stadium (St) is an element with the atomic number 51. It has a ground-state electron configuration of [Kr] 4d¹⁰ 5s² 5p³. In this configuration, the 5p subshell has three electrons, which are unpaired. Therefore, there are three unpaired electrons in stadium.
What element has the outer electron configuration 6s2 4f8?
No element has this as the ground state. Gadolinium has the right number of electrons but its ground state is [Xe] 4f7 5d1 6s2. The second number in each group should be a superscript.
