Ionic bonds form between a metal and a non-metal due to the large differences in electronegativity.
Since fluorine is at the left end of the table, it is the most electronegative element of the periodic table.
The innermost shell of an atom can contain up to 2 electrons.
The statement is "Compounds are made of more than one type of element bound together in fixed ratios.
" is true.
The statement is "Cesium (Cs) and chlorine (Cl) would likely form an ionic compound." is true.
Explanation:
An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion. In this way, the octet rule is fulfilled, which establishes that the atoms of the elements bind each other in the attempt to complete their valence layer, leaving the atom stable with 8 electrons in its last layer.
Given the above, Ionic bonds form between a metal and a non-metal due to the large differences in electronegativity.
Electonegativity is defined as the ability of an element to attract the electrons that bond it to another element. In the periodic table, electronegativity increases from left to right in a period, and from top to bottom in a group.This variation is due to the fact that, from left to right, the number of electrons in the valence layer is increasing, so that the attraction of other electrons to complete the valence layer and reaching a stable state is increasing. The decrease in electronegativity when lowering in the periodic table is usually attributed to the increase in the atomic radius; the valence layer is moving away from the nucleus and with it the attraction that the nucleus exerts on the valence electrons decreases.
Since fluorine is at the left end of the table, it is the most electronegative element of the periodic table.
There are 7 energy levels, numbered from 1 to 7, and in which electrons are distributed. Each level is divided into sub-levels. These sub-levels into which each level is divided can be up to 4. These 4 sub-levels are called: s, p, d, f. In the sub-level s there can only be a maximum of 2 electrons, in p there can be a maximum of 6 electrons, in the sub-level d 10 electrons and finally in the sub-level f there can be a maximum of 14 electrons.
At level 1, which belongs to the innermost layer of an atom, there is only one sub-level, which will be the s. As in the sublevel s there can only be a maximum of 2 electrons, then: The innermost shell of an atom can contain up to 2 electrons.
Compounds are substances that contain the chemical bond of two or more elements in defined proportions. That is, it is uniquely combined by means of a chemical action they can be separated. It is represented by chemical formulas that express the quantities and types of chemical elements that the components.
Therefore, the statement is "Compounds are made of more than one type of element bound together in fixed ratios.
" is true.
As mentioned earlier, an ionic bond is produced between metallic and non-metallic atoms. Cesium is a metal, while chlorine is a nonmetal. The, the statement is "Cesium (Cs) and chlorine (Cl) would likely form an ionic compound." is true.
