Log in. Which of the following ions is least likely to form? So we have to identify which of the following Qatar will be least likely to follow. So we have Arabic classical br minus mint has managed to any cables. So as we know that these were menace and self act are the numbers that that's why they have a tendency to gain electrons and as a medium and position both are metal.
So they will happen. Institute lose electrons prohibition. Is the elderly middle an electronic on february. Is that? And that's cool. And this one so if rotation lose one electron then it will gain in advance contribution.
So you'd have a high tendency to produce people's the women have also tendency to gain one electoral and sulfur also has Tendency to gain two electrons by Because grooming have gender electronic configuration NH two can be five if bringing gain one electron that it will gain in our guest configuration in the s minus group sulfur has general electronic contribution managed to end before if it gains to electronics then it will also do that in our gas configuration.
But in the case of the medium medium also elderly method. So the media Have gender electronic contribution and S one. So you'd have a tendency to lose only one electron North who from because after one electron it will can work into the inert gas from Russia and from analogous configuration one move electron removal is impossible because it is already stable. Are we trust to have the least tendency to form there's a correct of some are published. Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties.
Chemistry deals with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds.
Chemistry also involves understanding the properties and interactions of individual atoms and molecules for use in larger-scale applications. In chemistry and physics, matter is any substance that has mass and takes up space by having volume. All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, "matter" generally includes atoms and anything made up of them, and any particles and objects that act as if they have both rest mass and volume.
Combining the propensity of sodium to lose an electron and of chloride to gain an electron, we observe complimentary reactivity. When combined, the uncharged atoms can exchange electrons and in doing so, achieve complete valence shells. The resulting ions stick together due to ionic bonds opposite charges attract , leaving a crystal lattice structure of NaCl, more commonly known as rock salt. The reaction is as follows:. Ionization is not limited to individual atoms; polyatomic ions can also be formed.
When writing the chemical formula for an ion, its net charge is written in superscript immediately after the chemical structure for the molecule or atom. An alternative way of showing a molecule or atom with multiple charges is by drawing out the signs multiple times; this is often seen with transition metals. Chemists sometimes circle the sign; this is merely ornamental and does not alter the chemical meaning. The Roman numeral designates the formal oxidation state of an element, whereas the superscripted numerals denotes the net charge.
The two notations are therefore exchangeable for monatomic ions, but the Roman numerals cannot be applied to polyatomic ions. However, it is possible to mix the notations for the individual metal center with a polyatomic complex, as demonstrated using the uranyl ion UO 2 as an example.
It should be noted that it is possible to remove many electrons from an atom. The energy required to do so may be recorded in a successive ionization energy diagram. Boundless vets and curates high-quality, openly licensed content from around the Internet.
