Answer:
B = the number of protons
Explanation:
The atom of every elements differ from each other because of number of protons they have.
Every atom consist of neutron, proton and electron. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron.
The number of neutrons may be same but every atom have different number of protons.
Neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.
Symbol of proton= P+
Symbol of neutron= n0
Mass of proton=1.672623×10-27 Kg
Mass of neutron=1.674929×10-27 Kg
Answer:
Explanation:
Atomic radius is the measurement from the nucleus to the outer edge of the electron cloud.
As you go down a group (vertically) the atomic radius increases because more electron shells are added. As you go across a period horizontally, the atomic radius decreases.
If we look at the halogens group (17), we see they follow this order from top to bottom:
F - Fluorine
Cl - Chlorine
Br - Bromine
I - Iodine
Since it increases down the group, iodine must have the largest atomic radius.
Yeah!!
We have to have maple syrup.
Pancakes are a necessity...
Explanation:
Lime is an oxide of calcium(CaO). As a metallic oxide, it produces a basic solution when it reacts with water.
- The main reason why lime is added to lakes is to reduce acidity in the lake water.
Bottom muds in lakes are usually acidic and makes the water hypertonic. When lime is added, it reduces the pH of the water and causes acidity to reduce.
- Lime also helps to reduce the hardness of lake water to a good level.
- Lime also helps to release nutrients useful for photosynthesis of plants in the lake.
