Answer:
1 + net charge
Explanation:
The resulting ion will have
1 electron fewer surrounding the nucleus than the number of protons located inside the nucleus it will have a 1+ charge.
Answer:
When seeds begin to grow, or germinate, they develop roots to help them develop into plants. Food – A plant makes its own food through a process called photosynthesis. In photosynthesis, a plant uses the energy from sunlight to change carbon dioxide (from the air) and water (from the soil) into sugars called glucose.
Answer: 153
Explanation:
californium is a synthetic radioactive element found on the bottom row of the periodic table, along with other actinides.
It was first discovered in 1950 at the University of California Radiation Laboratory in Berkeley by bombarding curium with alpha particles (helium nuclei). Pure californium metal has a silvery-white appearance and is soft enough to be easily cut with razor blade.
In initial experiments with californium in its concentrated form began in 1958.
Since then, 20 isotopes of californium have been characterize, with mass numbers ranging from 237 to 256. One of these isotopes is californium-252, which was first isolated from a neutron-irradiated sample of plutonium-239. As an exclusively synthetically made element (it cannot be found in nature),
californium-252 is very rare an is produced via neutron bombardment in high flux isotope reactor or particle accelerators.
On this,page we walk through some of the properties and uses of his unique isotope and provide additional resources for your reference.
Hope this helps! :)
Explanation:
oxidation is adding of oxygen and removal of hydrogen.
Reduction means removal of oxygen and addition of hydrogenm
