Answer:
the mass of one mole of an element, or Avogadro's number (6.02 x 1023) of atoms, is equal to its atomic mass in grams. In other words, 1 amu = 1 gram/mole. So if the mass of one hydrogen atom is 1 amu, the mass of one mole of hydrogen is 1 gram.
Explanation:
There are 22 bonding parts
Answer:
A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry.
A series of six elements called the metalloids separate the metals from the nonmetals in the periodic table. The metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. These elements look metallic; however, they do not conduct electricity as well as metals so they are semiconductors. They are semiconductors because their electrons are more tightly bound to their nuclei than are those of metallic conductors. Their chemical behavior falls between that of metals and nonmetals. For example, the pure metalloids form covalent crystals like the nonmetals, but like the metals, they generally do not form monatomic anions. This intermediate behavior is in part due to their intermediate electronegativity values. In this section, we will briefly discuss the chemical behavior of metalloids and deal with two of these elements—boron and silicon—in more detail.

An electrochemical is a type of cell capable of generating electricity from chemical or facilitating chemical reaction through electrical energy
Answer:
The movement of electrons is kinetic energy, capable of producing electrical energy (option B).
Explanation:
An electron is a mobile subatomic particle, located outside the atom and forming elliptical orbits, unlike protons and neutrons. In addition, each electron has a negative charge.
<u>The energy on which the movement of the electrons depends is kinetic energy, which promotes this movement</u>. The interaction between the negative charges of the electrons and the positive charge of the protons produces electrical energy.
<em>The other options are not correct because the charge energy, electric energy and magnetic energy are consequences of the activity of the subatomic particles of the atom.</em>
