At the same time electrons are added to the atoms as you move from left to right across a period. Element bp K He 4 Ne 25 Ar 95 Kr 125 Xe 170. As you move from left to right the nucleus gains protons.
σtot σD σS. Unique Chemistry of the Lightest Elements. As you move from left to right across a period the physical properties of the elements change.
Explain the trends you observed for bromine chlorine magnesium sodium and phosphorus. These inner 3d electrons offer a poor shielding effect and thus valence shell electrons of Ga experience greater nuclear attraction. Using orbital energy arguments explain why electron configurations with more than four electron pairs around the central atom are not observed for second-period elements.
Which best explains the following trend. One loose trend is the tendency for elemental states to go from solid to liquid to gas across a period. See the answer See the answer done loading.

Experts are tested by Chegg as specialists in their subject area. This problem has been solved. Calulate the quantity of electricity required in coulomb.
Trends are based on Coulombs law which mathematically relates several characteristics of an elements. For its molar mass water has a high boiling point. This increases the positive charge of the nucleus and its attractive force on the electrons.
The melting point of an element is basically the energy required to change the state of an element from its solid state to its liquid state. A Covalent bond b Ionic bond c Hydrogen bond d Metallic bond 2. However ammonia NH 3 does not follow the.
