Commercialization is widely believed to be achievable for metal halide perovskite solar cells with high efficiency and low fabrication cost. However, stability remains a key obstacle for them to compete with established photovoltaic technologies. The pho
one of the defining characteristics of a metal is that it tends to lose electrons. However, the many elements of the transition metals family form cations with a variety of different charges; for this reason, there is no easy way to classify the ways in which these elements form cations. ...
In this group, elements are known as Halogens. The word Halogen means salt former. They are reactive non-metals and are always found in compounds with other elements. Valancy {eq}=7 {/eq}. Since the reactivity is high, they form salts when they react with Alkali metals. Examp...
Think about the electrons in the valence shell.On average, they’re evenly dispersed. But at any given instant, there might be a mismatch between how many electrons are on one side and how many are on the other, which can lead to aninstantaneousdifference in charge. ...
In general, chemists and other scientists can use the table to predict how certain elements will react with one another. The alkali metals, for instance, are in the first column or group of the table and tend to have one valence electron and so carry a charge of +1. This charge means ...
