QuestionIdentify the ion charge of selenium and provide its name. Charge: . Name: selenide.
Studdy Solution
STEP 1
Assumptions1. Selenium is a non-metal element in the periodic table.
. The ion formed by a non-metal element is an anion.
3. The charge of an anion is determined by the number of electrons it gains to achieve a stable electron configuration.
STEP 2
First, we need to find the atomic number of selenium. The atomic number of an element is the number of protons in the nucleus of an atom. It is also equal to the number of electrons in a neutral atom. Selenium is the34th element in the periodic table, so its atomic number is34.
STEP 3
The electron configuration of a neutral atom is determined by the atomic number. For selenium, the electron configuration is [Ar]3d10s2p.
STEP 4
To achieve a stable electron configuration, selenium needs to gain2 electrons to fill its4p orbital. When selenium gains2 electrons, it forms an anion with a charge of -2.
STEP 5
The name of the ion formed by selenium is selenide. When non-metal elements form anions, the end of the element's name is typically changed to "-ide".
The ion formed by selenium is called selenide and it has a charge of -2.
