Answer: C. Covalent bonds

Explanation: The bond between the 2 atoms can be formed by either sharing the electrons or by donating the electrons or by the method which fall under other types.

Thus when we talk about the sharing of electrons, there will be the formation of the Covalent Bonds. Covalent Bonds are the bonds which are formed by the sharing of electrons between 2 atoms in order to complete each others' octet.

Ionic bonds are the bonds which are formed by the transferring of electrons from one atom to the other one to complete octet.

Hydrogen bonds are the bonds which are formed by the electrostatic forces of attraction between the electronegative atom of the one species and acidic hydrogen of the another one.

A cylinder with a radius of 5.6 cm and a height of 10.7 cm has what volume? (You can look up the formula for the volume of a cyl

Keith_Richards [23]

Answer:

$V=1054.2cm^{3}$

Explanation:

1. First take the cylinder volume formula:

$V=\pi.r^{2}.h$

2. Then take the values for the radius and the height of the cylinder and replace them into the formula:

$V=\pi*(5.6cm)^{2}*(10.7cm)$

3. Solve the equation:

$V=\pi*(31.36cm^{2})*(10.7cm)$

$V=\pi*335.5cm^{3}$

$V=1054.2cm^{3}$

Which has a higher frequency, a neutron or electron? Why?

DanielleElmas [232]

The electron, due to the way an electron orbits the nucleus of an atom.

According to Quantum Mechanics, electrons do not really orbit the nucleus of an atom. In fact, the most tightly bound state, the 1s orbital, has no angular momentum at all. This would be the state with the most "kinetic energy" and yet there is no "orbital" motion at all in this state.
