Answer:
Atoms of elements at the top of a group on the periodic table are smaller than the atoms of elements at the bottom of the group. ... The valence electrons of the larger atoms are farther from the nucleus and are easier to remove, so the metals near the bottom are more reactive than those at the top.

Answer:
It is incorrect because sodium phosphate is a compound that has a single composition.
Explanation:
Sodium phosphate is a compound and not a mixture. It is made up of sodium and phosphate ions and they exists as just a single compound and not different entities.
The parts of a mixture exists separately and they retain their identities.
- In the compound a sodium phosphate we have 3 atoms, Na, P and Oxygen joined together in a definite grouping.
- The properties of the compound are different from the individual elements that makes them up.
Answer:
with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives known.
Explanation:
NTG reduces preload via venous dilation, and achieves modest afterload reduction via arterial dilation. These effects result in decreased myocardial oxygen demand. In addition, NTG induces coronary vasodilation, thereby increasing oxygen delivery.
