Majority of the atoms mass is found in the nucleus, which consists of protons and neutrons. Neutrons have a neutral charge, while protons have a positive charge.
Answer:
It shows no regular pattern
Explanation:
Physical properties of an element are those we can observe and feel with our senses. Also, the use special equipment can enhance our perception of these properties.
- The same physical property can be shared different number elements.
- On the periodic table, all the elements in group 1 and 2 are metals.
- This is not very useful for scientists whose emphasis is to distinguish one atom from the other.
- Therefore, physical properties are highly limited in the organization of the periodic table.
Explanation:
Convection requires a fluid material that can move around. Typically, metals are solid, not fluid, and therefore do not participate in convection. ... This means that metal can be either a good heat shield, a mediocre heat shield, or a bad heat shield, depending on how we use it.
2H3PO4 + 3Ca(OH)2 ➡ Ca3(PO4)2 + 6H2O.
Hence salt formed is Ca3(PO4)2.
Hope this helps, have a nice day!
