Answer:
Explained
Explanation:
The bond angle between the Si-O-Si is 145° .But this can also vary between 100° and 170°, It is because of which the changes in properties is happening. Bond angles can affect the hybridization, lone pair repulsion and electronegativity.
Thus , Space shuttle tiles, sandstone, and the glass in quartz have different properties and are used according to their property.
Answer:
A Newman projection, useful in alkane stereochemistry, visualizes the conformation of a chemical bond from front to back, with the front atom represented by a dot and the back carbon as a circle. The front carbon atom is called proximal, while the back atom is called distal.
Answer:
There is no chemical symbol for paper since it is not an element but rather a mixture of several different compounds. Mixtures in two or more phases are heterogeneous mixtures.
Explanation:
Answer:
The central portion is called neutron.
Explanation:
An atom has a central part known as nucleus and outer shells.
The central nucleus contains protons (the positively charged sub atomic particle) and neutrons (the neutral sub atomic particle).
The outer portion has negatively charged sub atomic particle known as electrons.
The atomic number of an element is the number of protons present in the nucleus.
