How many electrons are in the electron configuration for AR 18?
Potassium (K) atom has 19 electrons. The full electron configuration of Potassium (K) is 1s22s22p63s23p64s1. The abbreviated form – [Ar]4s1 – means the electron configuration of Argon (Ar), plus one electron in the 4s orbital. Argon has 18 electrons.
How many 3d electrons are in AR?
Argon has three electron shells. The third shell is filled with eight electrons. That is why it does not easily combine with other elements.
What does ground state mean in electron configuration?
Electron configurations can be determined using a periodic table. Terminology: The ground state configuration is the lowest energy, most stable arrangement. An excited state configuration is a higher energy arrangement (it requires energy input to create an excited state).
Which element has the electron configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p²?
Germanium has the electron configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p².
Which element has the ground state electron configuration 1s22s22p2?
The number of electrons equals the number of protons and this is the atomic number. So, the atomic number of the element is 6. In a periodic table you can find that the element with atomic number 6 is carbon. So the answer is C.
Which element has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p3?
antimony atom
What is the electron configuration for nitrogen atomic number 7?
The electronic configuration of an element is the arrangement of its electrons in its atomic orbitals. The atomic number of Nitrogen is 7 electronic configuration is 1s22s22p3. The first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for N goes in the 2s orbital.

How many electrons are in the outer shell of nitrogen?
five electrons
How many valence electrons does the ground state electron configuration of nitrogen have?
5 valence electrons
How many electrons are in energy level 3 of nitrogen?
eight electrons
How many electrons are in the highest energy level of nitrogen?

Which electrons have the most energy?
Electrons at higher energy levels, which are farther from the nucleus, have more energy. They also have more orbitals and greater possible numbers of electrons. Electrons at the outermost energy level of an atom are called valence electrons.
What element has four energy levels?
Bromine
