Ionic Bonds

Electron arrangement and trends in properties shielding the other electrons from the charge of the nucleus. As a result of this the other electrons are more strongly attracted to the nucleus, and the radius of the atom gets smaller. When an electron is added to an atom, forming an anion, the added electron repels other electrons, resulting in an increase in the size of the atom. In regards to the trend size of ionic radii is due to shielding of the outermost electrons by the inner-shell electrons so that the outer shell electrons does not get the positive charge of the nucleus. (Chemguide, 2016)
 Electronegativity
Electronegativity is a measure of the attraction an atom has for the electrons in the bond that are involved in a bond. An atom which has a high electronegativity would attract bonded electrons towards it, bringing them closer where as an atom which has a low electronegativity will have an extremely weak attraction for electrons. On a periodic table, electronegativity values increases from left to right and decrease on a descending group. (Clark, 2016)

Ionic bonds form when a non-metal and a metal exchange electrons, while covalent bonds form when electrons are shared between two non-metals. There are two bonds known as Ionic Bonds and Covalent Bonds. Ionic bonds form between metals and non-metals whereas covalent bonds are formed when electron are shared between two non-metals. An ionic bond is formed though an electrostatic attraction between two positively charged ions. Bonds between a partly ionic ion and a partly covalent ion is known as a polar covalent bond. A covalent bond is when electrons are shared between atoms and the most stable state is when the valence electron shell is full. Then, atoms form a covalent bonds share their valence electrons to get a more stable state. (Janet Rae-Dupree,

Covalent bonding - Covalent bonding is when two atoms share electrons this can only occur between two non-metals. They share electrons to fill up their outer shells, this makes the atoms stable. A Covalent bond can form up to one to three Covalent bonds with non-metals depending on how much electrons they possess. They don't always share electrons

Where as, electrons are negatively charged(Doc.3).The neutron is the dense middle of the atom(Doc.3). The protons and neutrons in the atom are in the nucleus(Doc.3). However, the electrons preside in electron clouds outside the nucleus(Doc.3). To sum up, an atom is a small structure that defines what an element is and

The electromagnetic force causes repulsion between the like-charged protons (positively charged). Both the electromagnetic force and the nuclear force act as opposites which can result in an nucleus being highly stable or highly unstable. This result is affected by which force is dominant in the nucleus, the more dominant the nuclear force it the smaller the nuclei and more stable the

• ionic compounds can only conduct electricity if their ions are free to move. Ionic compounds only conduct when they are melted or dissolved in water and they do not do not conduct electricity when they are solid. Sodium chloride– it is soluble in water, it has high boiling and melting point, it does not conduct in its solid state, except when it dissolves in water or melted then it will conduct electricity.

The higher the element's atomic number, the further away the two outermost electrons are from the nucleus. The further away the electrons are from the nucleus, the weaker their bond is and they are easily taken away. The easier they are taken, a bigger reaction occurs

Dylan Clayton Mrs. Beckwith Pre-Ap Physical Science 9 7 December 2015 The Importance of Electrons Electrons are the negatively charged subatomic particles that revolve the center, nucleus, of an atom. They are arranged in different energy levels and they orbit around the nucleus like the Earth revolves around the Sun. Electrons are important in atoms, compounds, and chemical bonds involved in chemical reactions. These subatomic particles have importanance to the organization of elements into periods & groups, characteristics of elements in the same periods & groups, and the formation of compounds based on periodic table placement.

Perpendicular Paramagnetic Bonding In chemistry, bonds are lasting attraction between atoms that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between atoms with opposite charges to form what is known as ionic bonds, or through the sharing of electrons to form a different bond known as covalent. These are the two well-known bonds that every chemistry class educates on.

Electrons were assigned the negative charge and the protons are assigned the positive charge. Although electrons carry the same amount of charge as a proton, they are much, much smaller furthermore they are in orbit around the nucleus, rather than in the nucleus itself. Experiments show that electrons that are orbiting very close to its nucleus is tightly held there by the strong positive charge flowing out of the center of the atom. However, electrons in outer orbits can sometimes be removed by frictional processes such as rubbing. Charged atoms.

COVALENT chemical bonding is the process in which two atoms share a pair of valence electrons. As the binary opposite to ionic bonding, covalent bonding processes lead to stable molecules once they share electrons in a particular method to create a noble gas configuration for each atom. (HyperPhysics,2014) Using hydrogen as an example which forms the simplest covalent bond, two hydrogen atoms contain one valence electron each where in the structure of an atom the 1st shell contains two electrons. The two hydrogen molecules contain one valence electron each and once paired together in a covalent bonding process form a single atomic atom.

This results in elements combining together to create a molecule, with subscripts (if necessary). Lastly, particles are referred as formula units. (ionically bonded- metal to nonmetal). Labelling them include pairing a metal element to a nonmetal. This will result in elements names combining together.

A covalent compound is formed when two or more nonmetal atoms share valence electrons; covalent compounds are also categorized into two sections: polar covalent and nonpolar covalent. Furthermore, polar covalent compounds dissolve in water, while nonpolar covalent compounds do not.
