They have similar electron configurations and have similar ionic chargers
It is the independent variable because you can ‘manipulate’ or ‘change’ it.
Answer: D
Explanation:
London forces become stronger as the atom in question becomes larger, and to a smaller degree for large molecules. [4] This is due to the increased polarizability of molecules with larger, more dispersed electron clouds. The polarizability is a measure of ease with which electrons can be redistributed; a large polarizability implies that the electrons are more easily redistributed. This trend is exemplified by the halogens (from smallest to largest: F 2 , Cl2 , Br 2 , I 2 ). The same increase of dispersive attraction occurs within and between organic molecules in the order RF<RCL<RBr<RI, or with other more polarizable heteroatoms. [5] Fluorine and chlorine are
gases at room temperature, bromine is a liquid, and iodine is a solid. The London forces are thought to be arise from the motion of electrons.
Binding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system.
Answer:
The element with electronic configuartion 1s² and atomic number 3 must be an cation.
Explanation:
The "Z" shows the atomic number. Z stand for zahl. It Is German word and meaning is " number".
In given question Z is equal to three which means an element with atomic number three.
Let consider the X is an element with atomic number three having electronic configuration 1s², but according to this atomic number there should be one more electron present is 2s. If X has the electronic configuration 1s² it means that it lose one electron and X is present in the form of cation.
X⁺ = 1s²
