Could you please give me answers for these ? thanks 1. Atomic radius decreases as we move from left to right in the periodic table. Which of the following is the BEST explanation for this trend? a. The electrons in the valence shell increase in number and thus interact more with one another as we move from left to right. b. There is more shielding of the inner electrons as we move from left to right. c. The electrons in...

In questions 2-4, you may use radius comparisons as given information. IONIZATION ENERGY. Ionization energy refers to energy required to remove an outer electron from an isolated atom. The energy tends to be less for elements with weaker attractions to the nucleus or higher initial energy levels. The general trend is for lower energy for elements lower in columns and higher energy from left to right across rows of the periodic table. There are some notable exceptions. Explain why: 2....

Human blood can contain the A antigen, the B antigen, both the A and B antigens, or nether antigen. It may or may not also | contain the Rh antigen. Blood is called type A-positive if the individual has the A and Rh but not the B antigen. A person having only the A and B antigens is said to have type AB-negative blood. A person having onty the Rh antigen has type O positlive blood. Other blood types recorded...
