What is atomic radius?

• the total distance from the nucleus of an atom to the outermost orbital of its electron. (Size atom )

• onic radius, rᵢₒₙ, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.

• in chemistry and physics, the amount of energy required to remove an electron from an isolated atom or molecule.

• is a chemical property that describes the power of an atom in a molecule to attract shared-pair electrons towards itself. There is a large ...

What happens when the attraction between nucleus and valence electrons increase

• greater atomic radius

• nothing

• decrease atomic radius

• nuclear reaction

Ionic radius - what if I add an electron what happens?

• cation

• anion

• bigger ion size

• anion, bigger ion size

ion size - what happens when you remove an electron

• cation

• loses one electron occupied shell

• smaller ion size

• all of the above

Ionization energy - How does the further away an electron is from the nucleus impacts the Ionization energy

• Smaller ionization energy because it is easier to pull it as the the nucleus and the valence electrons have a less attraction

• Smaller ionization energy because it is more cool

• Higher ionization energy because it is not easier to pull it as the the nucleus and the valence electrons have a less attraction

• Higher ionization energy because it is not cool

Periodic trends -Why does the electronegativity Increase right and up

• Because atoms have a greater atomic size

• Because atoms have a stronger hold on their own electrons, and attract electrons belonging to other atoms

• Because atoms need less ionization energy

• Because the ion size increases

Non metals do what?

• lose electrons

• Become anion

• all the above

• become cation

Metals do what?

• lose electrons and become anion

• Become anion

• all the above

• Become cation BECAUSE OF losing electrons

Metals that conduct electricity

• copper

• iron

• gold

• gallium

Metals

• Malleable

• Ductile

• Luster

• Brittle
