The electron configuration of arsenic is: [Ar]4s23d104p3.
There's two ways to answer this question. First electron configurations with half-filled sublevels are more stable then electron configurations that don't have half-filled sublevels. Since Selenium is one elctron away from achieving a more stable half-filled sublevel configuration it more readily gives up it's outermost electron, so less energy is requires to remove the outermost electron. Arsenic already has the stable configuration of half-filled sublevel so it wouldn't give up it's electron as readily, so more energy is required to remove it. Another way to look at it is that Selenium's outermost electron is in a p orbital that already has an electron so there is electron electron repulsion present in that orbital so it's attraction to the nucleus is less which is why less energy is required to remove it so the ionization energy is less. Arsenic has it's outermost electron unpaired in the p orbital so there is no electron electron repulsion present in that orbital so more energy is required to remove it then for Selenium's outer most electron. Hope this helps!
Losing an electron cesium has a noble gas configuration.
Electron configuration is a term applied to chemical elements not to compounds.
Silver has to give up 1 electron to achieve a pseudo noble gas electron configuration. With its atomic number being 47, silver has an electron configuration of [Kr] 4d^10 5s^1. Giving up its one valence electron from the 5s orbital will result in a stable pseudo noble gas electron configuration similar to argon.
Silver (Ag) has 47 electrons. To achieve a pseudo-noble gas electron configuration, silver would need to give up one electron to match the electron configuration of the noble gas, krypton (Kr), in which the outermost energy level is full. This would leave silver with 46 electrons.
The electron configuration for a neutral atom of chlorine is 1s2 2s2 2p6 3s2 3p5. Chlorine has 17 electrons, and this configuration indicates the distribution of those electrons in its various energy levels.
The electron configuration for a neutral atom of phosphorus is 1s2 2s2 2p6 3s2 3p3. This means phosphorus has 15 electrons distributed among its energy levels.
Neutral calcium's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. Ca2+ is the ion of calcium, which means that it has 2 less electrons than neutral calcium. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6.
Arsenic is paramagnetic because the electron configuration is {Ar}4s^2,3d^10,4p^3. Due to the unpaired electron at the end (4p^*3*) the atom in ground state is paramagnetic. **OR Arsenic would be paramagnetic since the 4 p orbitals each contain one electron with parallel spin. These three unpaired electrons give arsenic its paramagnetic property.

Two electrons
Silver has to give up 1 electron to achieve a pseudo noble gas electron configuration. With its atomic number being 47, silver has an electron configuration of [Kr] 4d^10 5s^1. Giving up its one valence electron from the 5s orbital will result in a stable pseudo noble gas electron configuration similar to argon.

Boron must give up 3 electrons in order to achieve a noble-gas electron configuration.
Silver (Ag) has 47 electrons. To achieve a pseudo-noble gas electron configuration, silver would need to give up one electron to match the electron configuration of the noble gas, krypton (Kr), in which the outermost energy level is full. This would leave silver with 46 electrons.
