carbon
The number of protons in the nucleus, which determines the element's identity, has the greatest effect on an element's properties. The number of electrons determines its chemical behavior, while the arrangement of electrons in energy levels plays a role in its physical properties.
This is probable iron.

Chemical weathering would likely have the greatest effect within the tropics due to the warm and humid conditions that promote chemical reactions and the breakdown of minerals. High temperatures and abundant rainfall accelerate the decomposition of rocks and minerals in tropical regions.
Water is the substance that has the greatest effect on the rate of weathering of rock. Water can seep into cracks in rock, freeze and expand, causing the rock to break apart. Water can also chemically react with minerals in the rock, leading to chemical weathering.
It's hard to answer this question, because it has a very large indirect effect, but very little direct effect. The number of protons in the nucleus determines what the element is, which in turn determines its chemical propertes. However, the nucleus does not itelf take part in chemical reactions.
Chemical properties of a element is governed by ELECTRONIC CONFIGURATION of that element. As isotopes of same element have identical electronic configurations, their chemical properties are same.
It had the greatest effect on the railroad industry.
The CFC's have greatest effect. They react with ozone to deplete it.
Water, or the lack of water, has the greatest effect on cacti.
CFc's have the greatest effect. the decompose ozone.
O (oxygen), N (nitrogen), H (hydrogen), Cl (chlorine), Br (bromine)
