英语翻译The atomic radius decreases on going from left to right across a period,because of the increasing nuclear charge,which exerts a greater attractive force on the outer electrons.The screening effect is observed in atoms with an atomic number greater than 2.重点翻译这2个句子.最好能帮我分析...
table of elements. the size of an atom generally decreases as one moves from left to right for a certain period. in general, the atomic radius decreases across a period and increases down a group. francium has the largest atomic radius, while helium has the lowest. frequently asked questions...
Atomic radius generally increases as we move ___. A. down a group and from right to left across a period B. up a group and from left to right across a period C. down a group and from left to right across a period D. up a group and from right to left across a period E. ...

El ión sodio va a tener un radio no muy diferente que el neón. QED The last trend we could talk about is just atomic radius. La última tendencia que podríamos hablar es sólo radio atómico. QED Atomic radius decreases across a period and increases down a group in the periodi...
State True or False. Effective nuclear charge is the positive charge experienced by the electron from the nucleus and it increases from left to right across the period. Answer true or false: Within a period, elements with lower atomic numbers have atoms of smaller radius because...
Atomic Size & Atomic Radius - Atomic Size is the distance between the center of the nucleus and the outermost shell of electrons is called the atomic radius. Atomic radii can be measured by measuring the distance between the nuclei of atoms in a metal. T
The decrease in the atomic radius across the period is due to decrease in effective nuclear charge with increase in atomic number. Down the group atomic number increases with increase in atomic number. As we move down the group a new shell is added, which means the distance between nucleus ...

atomic radius decreases as you move from left to right across a period of the periodic table. The protons and electrons in an atom increase, but the electrons fill valence shells in the same energy level. The electron cloud does not grow substantially in size, but the net charge of the nu...
