A neutral object is sketched below, in black and white. There are positive and negative electric charges inside this object, and at least some of those charges can move around. Now suppose a positive charge comes close to this object, as shown in the sketch. Shade the object red anywhere you expect it to become more negatively charged, and shade the object blue anywhere you expect it to become more positively charged.

The following charge interactions between balloons A, B and C are observed. It is known that balloon B is charged negatively. Based on these observations, determine the possible charges (positive, negative, or neutral) of balloons A and C and explain your reasoning.
2. A charged particle is caused to move between two electrically charged plates, as shown here. +) (a) Why does the path of the charged particle bend? (b) What is the sign of the electrical charge on the particle? (c) As the charge on the plates is increased, would you expect the bend- ing to increase, decrease, or stay the same? (d) As the mass of the particle is increased while the speed of the particles remains the same, would you expect the bending to increase, decrease, or stay the same?
Which ionic compound is expected to form from combiningthe following pairs of elements? (a) barium and fluorine,(b) cesium and chlorine, (c) lithium and nitrogen, (d) aluminumand oxygen.
You are spending the summer working for a chemical company. Your boss has asked you to determine where a chlorine ion of effective charge -e would situate itself near a carbon dioxide ion. The carbon dioxide ion is composed of 2 oxygen ions each with an effective charge -2e and a carbon ion with an effective charge +3e. These ions are arranged in a line with the carbon ion sandwiched midway between the two oxygen ions. The distance between each oxygen ion and the carbon ion is 3.0 x 10-11 m. Assuming that the chlorine ion is on a line that is perpendicular to the axis of the carbon dioxide ion and that the line goes through the carbon ion, what is the equilibrium distance for the chlorine ion relative to the carbon ion on this line? For simplicity, you assume that the carbon dioxide ion does not deform in the presence of the chlorine ion. Looking in your trusty physics textbook, you find the charge of the electron is 1.60 x 10-19 C.
what does it mean when an ion has a positive charge? The expression "opposites attract" occurs in chemistry. What does the expression mean when it applies to ions?
Look at the following graph. Explain what trend you are observing and how it relates to atomic radius and 1st ionization energy. (How does ionization energy and atomic radius impact electronegativity?)
(b) A new element, "X", is discovered and found to have 2 electrons in its outer level. Is X a metal or non-metal? Predict the formula its ion would have in any ionic compounds it forms.
1. What is ionization energy? How does it change as you go across a row in the periodic table? Be sure to use the coulombic attraction between electrons and the nucleus in your explanation. 2. How does ionization energy change as you go down a group in the periodic table? Be sure to use the coulombic attraction between electrons and the nucleus in your explanation.
1. Arrange the following ions in order of increasing ionic radius: chloride ion, potassium ion, phosphide ion, calcium ion.
Chlorine atoms tend to gain 1 electron to form chloride anions. What is the charge on a chloride anion?
As seen in the table, compounds containing an integer ratio of elements depend on how many cations combine with how many anions to form a stable compound. For example, in table 1, to form a NaCl compound, first Na ionizes from the Na+ cation which is having +1 positive charge, which will lose 1 electron, it is having +1 charge, this electron then goes to Cl and it will change to Cl- anion by gaining the electron, so here 1:1 ratio charge which means 1 Na+ combines with 1 Cl-1 to form NaCl. So here integer ratio is 1:1 for this sodium chloride compound. As listed in table 2, Mg(OH)2, the integer ratio is 1:2 which means, Mg is a neutral atom that loses 2 electrons and forms an Mg+2 cation, which combines with OH which gains 1 electron to form OH- anion, So here Mg2+ can combine with 2 OH- anion, so they both combine to form Mg(OH)2 which has integer ratio as 1:2 . Thus, atom forms as ions by losing or gaining electrons and combines together in whole number ratio to form stable…
