Answer:
Option D and Option B
When comparing the two elements K and Ge , the more metallic element is_____K_____ based on periodic trends alone.
When comparing the two elements Sb and Pb , the more metallic element is_____Pb______ based on periodic
Explanation:
The metallic characteristic increases when we move down a column in a periodic table or when we move left in the row.
Potassium and Germanium are located on the same row, but germanium lies on the right side of potassium. Thus, potassium (K) is more metallic than Germanium (Ge)
While Lead (Pb) lies to left of Sb in the adjacent column and is also lies below Sb. Hence Pb is more metallic than Sb
Answer: Well every human is different and some can have different traits that the rest of there family doesn't have. The human DNA can mix and form a different trait that the rest of the family doesn't have.

Answer : The symbol of the element is Selenium (Se).
Explanation :
Electronic configuration is distribution of electrons in an atom in atomic orbitals.
The electronic configuration of [Kr] =
Total number of electrons in [Kr] = 36
Due to -2 charge, 2 electrons are withdrawn from the electronic configuration of [Kr].
Now the total number of electrons left = 36 - 2 = 34
And the Selenium[Se] is the element which has 34 number of electrons.
Electronic configuration of [Se] =
