Answer: An atom that has gained an electron.
Explanation:
The number of protons in an atom cannot change except for some exceptional circumstances.
Cations (or metal ions) are formed when atoms lose electrons, as they want to form a complete outer electron shell to become as stable as possible.
For example, potassium is a 1+ ion, because it has one electron in its outer shell (and in group one). Therefore, to become more stable that electron is lost to become an ion or cation. As one electron is lost, the potassium cation charge is 1+ as the charge of an electron is 1-.
Answer:
A. Actual Yield
Since all of the others are calculated not measured outright.
Inorganic compounds contain carbon. Inorganic compounds usually lack carbon. Inorganic compounds are not associated with or made from living things
Lead (Pb) has the electron configuration [xe] 6s2 4f14 5d10 6p2.
<h3><u>
What is electronic configuration ?</u></h3>
A neutral element's total number of electrons is represented by its electronic configuration. To get the total number of electrons in an atom, we sum all the superscripts.
As the last electron enters the p orbital, the provided element is a p block element. Xenon, a noble gas with 54 electrons, is the closest.
According to Afbau's rule, the electrons are filled in the sequence of increasing energies, and the electronic configuration in terms of the noble gs configuration is as follows:
Total electrons = 54 + 2 + 14 + 10 + 2 = 82
Lead is the element with the symbol whose atomic number is 82 since it contains 82 electrons.
