1-Describe the periodic tendency in atomic radius and associate it to atomic construction 2- Describe the periodic tendency in electronegativity and associate it to atomic construction Did you cognize?
There are atoms with no electronegativity because electro negativeness refers to the attractive force of atoms of negatrons in a compound ; elements that do non organize are assigned no electronegativity values. Atomic Radius ? Ionization Energy

As you move from left to compensate on the periodic tabular array. the figure of cornice negatron addition. As the figure of E increases P additions. As positive force additions. the negatron get tighter and the radius gets smaller. Ionization energy is the energy required to take an negatron. As you move up and down the periodic tabular array. the figure of negatron shells alterations. As the figure of shells additions. there is more screening between the karyons the outermost negatron additions. Atomic Radius: is half the distances between 2 indistinguishable atoms that are bonded. It is the distance between the karyon and the outer shell.

Electro negativeness:
When atoms are bonded together. unless they are 2 indistinguishable atoms. one of those atoms is ever traveling to be better at pulling negatrons to it. Electronegativity: is the ability of an atom to pull negatrons to itself. Electronegativity: will increase when it goes from left to compensate and down to up and will diminish when lessenings goes from right to go forth electronegativity and up to down. Atomic radius: lessenings from left to compensate and down to up. and increases from right to left and up to down. Ionization Energy: will increase when it goes from left to compensate and down to up and will diminish when lessenings goes from right to go forth electronegativity and up to down. As we move fro. left to compensate on the periodic tabular array the atomic radius lessenings. and as it decreases. the karyon is better able to pull negatrons to it. So. electronegativity increases traveling from left to right. As you move from top to bottom. the atomic radius additions. As it increases. the figure of interior shells increases. As it increases the karyon is less able to pull negatrons to it. Chapter4 subdivision 3

Melting point: is the temperature at which a substance turns to a liquid from a solid. Boiling point: is the temperature at which a substance turns to gas from a liquid. The metals have high thaw and boiling point because they are solids at room temperature Gases and liquids have low thaw points and boiling points because they are liquids and gases at room temperature.

Aims:
1 ) Determine an atoms figure and cornice negatrons. and utilize the eight regulation to foretell what stable ions the atom is likely to organize.

The ions on the periodic tabular array have the same negatron constellation as the baronial gases. This happens because elements form ions in such a manner that they will accomplish a baronial gas negatron constellation.

The passage metals can hold multiple charges when they form positive ions each metal can hold more than one possible charge. The charge that it will transport depends on the conditions. The passage metals do non organize ions in a manner that will accomplish a baronial gas negatron constellation.
