What Element Has 14 Protons and 13 Electrons?

The element with 14 protons and 13 electrons is known as Silicon. This element is found in great abundance in rocks and sand, and it is also the main component of computer chips. It has a very stable nucleus, and is used in various industrial and medical applications.

This element is called selenium. Selenium is a nonmetal, with an atomic number of 34, and is represented by the chemical symbol Se. It is a grayish-white, lustrous, brittle solid that has a metallic luster. It is a poor conductor of electricity, and has a high melting point and boiling point. Selenium is found in nature chiefly as the sulfide mineral, pyrite (FeS2), or as selenide ores. These ores are mined and converted to selenious acid (H2SeO3), which is the principal compound of selenium.

The most common symbols for this element are H and atomic number 1. The atomic number 1 is always written as a subscript, and hydrogen is the only element with this atomic number. The H symbol comes from the Latin word for hydrogen, hydrōgenium.

The origin of the word hydrogen is uncertain. Most likely, it is from Ancient Greek, which has many possibilities. One theory is that it comes from hydro- meaning "water" and -genes meaning "born" or "generated", thus meaning "water-born". Another theory is that it comes from hydro- meaning "water" and -gen meaning "creator", thus meaning "water-creator".

When Did scientists first identify hydrogen?

Hydrogen was first identified in the early 18th century by English chemist Henry Cavendish. However, Cavendish did not realize that it was an element. He simply observed that when he mixed certain acids with certain metals, he obtained a flammable gas. It was not until 1766 that hydrogen was recognized as a distinct element by Swedish chemist Carl Wilhelm Scheele.

This question can be difficult to answer, as there is no definitive answer. The group number is an indication of the elements position in the periodic table, and as such, can be used to predict some of its physical and chemical properties. However, the group number alone does not determine all of an element's properties, so it is not always a reliable predictor. There are other elements in the same group as the element in question, and these can have different properties. The group number can be a helpful tool for understanding an element's behavior, but it is not the only factor to consider.
