Question: Can you please help me answer all questions ? i really need your help im confused 1) The element is the most similar to nitrogen


1) The element is the most similar to nitrogen in chemical and physical properties. Hint look for common elements that are in the same group A) C B) C) D) Ne E) LI 2) of the following contains the greatest number of electrons. A) S2+ B) S CS D) S E) S2 3) Which one of the following is most likely to lose electrons when forming an ion? Hint look for elements with the lowest electronegativity A) Na B) O C) F D) Ne E)N 4) Aluminum is a A) nonmetal, metal D) metalloid, nonmetal and phosphorus is a B) metal metal E) metal nonmetal C) metal metalloid 5) Anions tend to have a A) positive D) large charge B) negative E) small C) neutral 6) typically form ions with a 1+ charge A) Alkaline earth metals B) Halogens D) Alkali metals E) Transition metals C) Chalcogens 7) Calcium forms an ion with a charge of A) 1+ B) 1- D) 2- E) 0 C)2+ 8) Nitrogen forms an ion with a charge of A) +5 B)-5 D-3 E) 0 C) =3+ 9) Which of the following compounds would you expect to be ionic? Hint look at elecronegativies A) CO B) H20 C) SO2 D) K20 E) O 10) Which pair of elements is most likely to form an ionic compound with each other? Hint look at differences in electronegativity - the greater the more likely to be the case A) strontium, iodine B) magnesium, lithium C) oxygen, chlorine D) carbon fluorine E) nitrogen, helium 11)Which of the following ions would be iso-electronic with Ac? Iso electronic means same number of electrons. Hint, look up element in the periodic table and use the atomic number as the number of electrons for the neutral atom. If the element has a negative charge, add that number to the amount of electrons. If it has a positive charge, subtract that number Example, F-has 10 electrons (Fluorine has 9 electrons but the minus one makes it 10) A) A1+3 B) 0-2 C) C- D) Mg+2 E) Ne
