What is the charge number?

One of the most basic driving forces of chemical reactions is electron bonds created between atoms. Electrons are negatively charged particles that circulate the core of the atom in the shells. Each electron shell has a set number of electrons it retains, if possible, even if it does not last a clean atom; Electrons and protons have the same amount of electric charge individually. The amount of charge that the atom has is expressed as Superscript to the right of the name of the element; For example, on 1+. The number and sign of the superscripts are known as the charge number.

The outer electron shell of the atom is called a valence shell and is the basis of chemical reactions. Each shell has a different number of electrons: the innermost shell contains two electrons, another contains eight and the following contains 18. The hub number comes from the natural tendencies of atoms to have a full valence shell, whether it includes or closer to electrons. The elements are arranged in a periodic table in sKupinách according to the number of electrons in their valence shells. If two elements are in the same column or in a group in the periodic table, they have the same number of electrons available for chemical reactions.

With the exception of hydrogen, elements on the left side of the table-group I and II-alkaline metals and alkaline earth metals. They have valence shells that are virtually empty, with only one or two electrons. Groups III through VII are non -metal. Group III has three electrons, Group IV has 4 and so on. Lifted gases, such as neon, radon and xenon, are full of valence shells and therefore do not respond with other elements.

The charge number determines what type of charge the atom will have if the electrons get during the ion chemical reaction. For example, sodium loses one electron when it reacts with chlorine; Chlorine gets one electron. Their relevant fees are 1+ and 1-. In its natural stateAll elements have a number of zeros because there is no profit or loss of electrons.

Transition elements in columns 3 to 12 periodic tables can connect with different elements. Their fees numbers will therefore differ. Group IV elements, such as carbon, have a number of cartridges 4+/4-. They tend to create covalent links with other atoms in which electrons are more shared than transmitted.
