2. Which of the following is the reason that ionization energy generally increases from left to right across the first period of the periodic table?
(A) As the atomic number increases, the electrons are harder to remove.
(B) Ionization energy increases as the atomic number increases in a period.
(C) As the atomic number increases, more electrons are
added to the atoms, thus increasing the electron-electron repulsions.
(D) As the atomic number increases, more protons in the
nucleus cause an increase in the effective nuclear charge,
making it harder to remove the electrons.

56.16 gregor mendel was the first scientist to use statistics to analyze scientific data. before mendel's experiments, scientists believed that organisms acquired traits from their environment and passed them on to their offspring. after mendel's discoveries were accepted, scientists realized that traits passed to offspring were the result of genes being passed from parents to offspring. this is an example of pls
