1 The cause of this most common type of cardiomyopathy often is unknown. 2  It may be caused by reduced blood flow to the heart (ischemic heart disease), infections, toxins and certain drugs. 3  It also may be inherited from a parent. 4  It usually enlarges (dilates) the left ventricle.ommon causes of abnormal heart rhythms (arrhythmias) or conditions that can lead to arrhythmias include: 1  Heart defects you're born with (congenital heart defects). 2  Coronary artery disease. 3  High blood pressure. 4  Diabetes. 5  Smoking.
The second ionization energy is always larger than the first ionization energy, because it requires even more energy to remove an electron from a cation than it is from a neutral atom. The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.
Veiw a periodic table with first ionization energies. Definition: Second Ionization Energy is the energy required to remove a second outermost electron from a ground state atom. Subsequent ionization energies increase greatly once an ion has reached the state like that of a noble gas.) As you move across a period, first ionization energy increases. WHY? - As you move across a period, the atomic radius decreases, that is, the atom is smaller. The outer electrons are closer to the nucleus and more strongly attracted to the center. Therefore, it becomes more difficult to remove the outermost electron.
