Recall that atoms gain or lose electrons to become lons. So, an lon has a different number of electrons than its corresponding neutral atom. Positive ions have lost electrons, and negative lons have gained electrons.
The table includes the electron configuration of several lons. Complete the rows for magnesium and oxygen (oxide) lons
by identifying the correction charge, electron configuration, and neutral atom with the same configuration as the lon.
You may need to use online resources or the periodic table to determine the correct lon charges.
Select the correct answer from each drop-down menu to complete the table.

balanced chemical equations follow the law of conservation of mass and charges. the masses and charges on either sides of the equation should be balanced.in conservation of mass, the number of atoms of each element on left side should be equal to the number of atoms of each element on the right side of the equation.1)k₂so₄ + 2ca(no₃)₂ --> 2kno₃ + 2caso₄number of ions left side right side k⁺ 2 2so₄²⁻ 1 2ca²⁺ 2 2no₃⁻ 4 2in this equation the masses of so₄²⁻ and no₃ are not balanced. therefore this equation violates the law of conservation of mass2)ti + 2 cl₂ > ticl₄ left side right side ti 1 1cl 4 4this equation follows the law of conservation of mass3)2c₂h₂ + 5o₂ > 4co₂ + 2h₂o left side right side c 4 4h 4 4o 10 10this equation follows the law of conservation of mass4)baso₄ + 2naoh --> ba(oh)₂ + na₂so₄ left side right side ba 1 1so₄²⁻ 1 1na 2 2 oh⁻ 2 2this equation follows the law of conservation of massanswer is 1st equation

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
