The mathematical expression for the hydrogen 1s wavefunction is (r) (1/a3) e(-r/a), where r is the distance from the nucleus and a is the Bohr radius.
A Slater determinant is a mathematical expression used in quantum mechanics to describe the arrangement of electrons in an atom or molecule. An example of a Slater determinant for a simple case would be the arrangement of two electrons in a hydrogen atom, where one electron is in the 1s orbital and the other is in the 2s orbital.
Covalent bonds are formed when atoms share electrons. Let's take hydrogen for example. To be the most "happy" atoms want their outermost orbital full of electrons. Hydrogen has only one electron in its 1s orbital, but the 1s orbital can hold two electrons. Hydrogen wants two electrons to be "happy" so it will do what it takes to get them. If a hydrogen atom bumps into another hydrogen atom they can both become "happy" as each atom will share its electron with the other atom, giving each a full outermost orbital with the help of the other atom's electron. This is what creates the bond in covalent bond as the hydrogen atoms are "happier" together with a full orbital than they would be with a half-full orbital apart.

The electron configuration for Neon is 1s2 2s2 2p6. This means that Neon has 10 electrons, with 2 in the 1s orbital, 2 in the 2s orbital, and 6 in the 2p orbital.
The electron configuration of CCl4 is 1s^2 2s^2 2p^6 3s^2 3p^2. This means that the carbon atom has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, 6 electrons in the 2p orbital, 2 electrons in the 3s orbital, and 2 electrons in the 3p orbital.
There is one thing that is relative to both helium and hydrogen. Both of these are a type of chemical.

Hydrogen has a shell of just 1 electron. 1s
As it has two postively charged protons in it (along with two neutrons), a Helium nucleus has two electrons 'orbiting' around it. Knowing this, we need to find which orbits they are in. The lowest energy orbital in an atom is made up of a single 'S' orbital (the 's' describes its shape - spherical) with a principal quantum number of 1 (which indicates the size of the orbital, 1 being the smallest). This is therefore denoted 1s . This orbital can accept two electrons, so both of the helium electrons go into it. The way to express this as a electron configuration is 1s2 , the superscript '2' indicating the number of electrons in the orbital. Feel free to stop at that point. To be a bit more technical, when we write 1s2 the '1s' is actually a mathematical wavefunction, and the superscript '2' is there because there are two electrons whose wavefunction is 1s, and so we multiply those wavefunctions together - hence the configuration actually means 1s-squared.
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.
The element with the electron configuration 1s1 is hydrogen, which has 1 electron in its 1s orbital.
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.
It is simple: 1s^1 Note: The "^" symbol means the the following number is in the form of a superscript.
The single electron in a neutral hydrogen atom resides in the 1s orbital.
1s. Orbit(s) 1, spin s.
The electron in a hydrogen atom is most likely to be found in the 1s orbital.
