Answer:
Here's what I get
Explanation:
Both diamond and SiO₂ are network solids. Their atoms are all joined together so a crystal of either diamond or SO₂is one giant molecule.
Structure
In diamond, each C atom is covalently attached to four other C atoms.
The structure of SiO₂ is like that of diamond. The difference is that there is an O atom between each atom of Si.
Properties
Both substances are
- High-melting
- Hard
- Insoluble in both polar and nonpolar solvents
- Poor conductors of electricity
She will use the periodic table of elements to not only find out the chemical symbols of the elements written within the name, but also to check whether or not the elements are metals and or nonmetals, from this determine the ionic charges if needed for metals, and for metals that have more than one ionic charge, use a Roman numeral to represent the ionic charge that she would be using in writing the chemical formula of the compound.
The Bohr radius of an electron in n=3 orbit of H atom is 4.77×.
<h3>What does Bohr's radius mean?</h3>
The mean radius of an electron's orbit around the nucleus of a hydrogen atom in its ground state is known as the Bohr radius and is denoted by the letter a. (lowest-energy level).
The Bohr radius equation used to find the radius of an electron's orbit is as follows:
Here,
n is the energy level.
h the Plank's constant.
is a constant related to the attraction of charges in a vacuum.
is the mass of an electron.
e is the charge on an electron.
For n=3 orbit of H atom,
The Bohr radius of an electron in n=3 orbit of H atom is 4.77×.
