Electron transfer is the term for this process. The resulting anion and cation are attracted by Coulombic forces and an ionic co

mpound is formed. Ionic compounds are neutral: the number of electrons lost in forming the cation(s) must equal the number gained in forming the anion(s). For example, Aluminum (Al, Z = 13, Group 3A or 13) will lose 3 electrons to become Al3+ which is isoelectronic with Neon (Ne), its closest noble gas. To form an ionic compound those 3 electrons must be picked up by a nonmetal. Two possibilities are:
Nitrogen (N, Z = 7, Group 5A or 15) gains all 3 electrons to become isoelectronic with Neon (Z = 10). The compound formed is AlN

3 Chlorine atoms (Cl, Z = 17, Group 7A or 17) each gain 1 electron to become isoelectronic with Argon (Ar, Z = 18). The symbol for the compound formed is AlCl3. The subscript after Cl indicates that 3 Cl- anions are required.

<h2>The compound formed is NaCl and CaCl_{2}</h2>

Explanation:

     PART 1:

  • Atomic number of sodium is 11.
  • Sodium(Na, Z = 11, Group 1A) will lose 1 electron to become Na^{1+} which is isoelectronic to Neon (Ne ,Z = 10).
  • The symbol for the sodium ion is Na^{+}.
  • Chlorine atom (Cl, Z = 17, Group 7A or 17) gains 1 elecron to be  isoelectronic to neon.
  • The symbol for the compound formed is NaCl.
  • PART 2:
  • Atomic number of calcium is 20
  • Calcium(Ca, Z = 20 ,Group 2A) will lose two electrons to become Ca^{2+}which is isoelectronic to argon.
  • The symbol for the ion is Ca^{2+}.
  • Two chlorine atoms (Cl, Z = 17, Group 7A or 17) each gains one electron to be isoelectronic to argon(Z = 18)
  • The symbol for the compound formed is CaCl_{2}.

The monatomic ions of Groups 1A(1) and 7A(17) are all singly charged. In what major way do they differ? Why?
insens350 [35]

<u>Answer:</u> Group 1 ions are known as cations and Group 17 ions are known as anions.

<u>Explanation:</u>

Ions are formed when an atom looses or gains electrons.

If an atom gains electrons, it leads to the formation of negative ions known as anions. <u>For Example:</u> Fluorine is a Group 17 element which gains 1 electron to form F^- ions.

If an atom looses electrons, it leads to the formation of positive ions known as cations. <u>For Example:</u> Sodium is a Group 1 element which looses 1 electron to form Na^+ ions.

Hence, group 1 ions are known as cations and Group 17 ions are known as anions.

How are objects charged by friction
mote1985 [20]

Answer:

When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged

What mass of cu(s) is electroplated by running 26.5 a of current through a cu2+(aq) solution for 4.00 h?
kramer
T = 14400 s 
26.5 x 14400=381600 C 
381600/96500=3.95 Faradays 
Cu2+ + 2e- = Cu 
3.95 faradays ( 1 mol/ 2 Faradays) = 1.97
mass = 1.97 x 63.55 g/mol=125 g 

moles Au = 33.1 / 196.967 g/mol=0.168 
Au+ + 1e- = Au 
0.168 ( 1 Faraday/ 1mol)= 0.168 Faraday 
0.168 x 96500=16217 Coulombs 
16217 / 5.00=3243 s => 54 min
