What is helium in relation to hydrogen?
The atomic number of helium is one more than that of hydrogen. In both the elements, the electrons are filled in the 1s orbitals. Hydrogen has one electron, helium has two.
How does the ground state electron configuration of the hydrogen atom differ from that of a ground state helium atom?
The ground state electron configuration of hydrogen is 1s^1, meaning it has one electron in the 1s orbital. Helium in its ground state has an electron configuration of 1s^2, indicating it has two electrons in the 1s orbital. So, the main difference is that hydrogen has one electron in its outer shell while helium has two electrons in its outer shell.
Since the first energy level contains only the 1s sublevel the number of elements in this period is?
The first period in the periodic table contains two elements: hydrogen and helium. Hydrogen has one electron in its 1s orbital, while helium has two electrons in its 1s orbital.
What has a 1s 1 orbital?
One option is a helium atom. Another is a Lithium cation. Or a beryllium cation. Or boron for that matter. Cause Li would be 1s2 2s1, Be would be 1s2 2s2 and Boron would be 1s2 2s2 2p1 so if they were to lose their valence electrons to become ions (cations) then they would have a 1s2 orbital. :D
Is a hydrogen atom different from a helium atom?
Helium has a nuclear charge of +2 and 2 electrons in a 1s orbital. Hydrogen has a nuclear charge of +1 and just one electron in a 1s orbital. The extra charge on the nuclees means that the electrons in He are more tightly bound than in hydrogen thuis reflected in the ionization energy of 2372 kJ/mol for He and about 1312 kJ/mol for hydrogen. For helium t the "outer shell" is full, a "stable " configuration.
How is a hydrogen atom different from a hydrogen atom?

What is the abbreviated ground state electron configuration for helium?
The abbreviated ground state electron configuration for helium is 1s^2. Helium has 2 electrons, both of which occupy the 1s orbital.

How many electrons are in the outer energy level of a helium atom?
Helium and hydrogen and group 3 to 12 got 2 valence electron
How many electrons is there in the outer most energy level?
For Hydrogen and Helium, the valence band [1S] holds two electrons. For the next series of the periodic table, eight electrons fill the two valence bands, 1S and 3P (two each equals 8).
How do you write a ground state electron configuration of ammonia?
Ammonia (NH₃) consists of one nitrogen atom and three hydrogen atoms. The ground state electron configuration for nitrogen is 1s² 2s² 2p³. For hydrogen, the configuration is simply 1s¹, but since there are three hydrogen atoms in ammonia, you can represent them as 3 × 1s¹. Therefore, the overall electron configuration for ammonia can be expressed as 1s² 2s² 2p³ (for nitrogen) + 3 × 1s¹ (for hydrogen).
What is hydrogen's shell structure?
Hydrogen has a shell of just 1 electron. 1s
