Answer:

For example, a suitcase jam-packed with clothes and souvenirs has a high density, while the same suitcase containing two pairs of underwear has low density. Size-wise, both suitcases look the same, but their density depends on the relationship between their mass and volume. Mass is the amount of matter in an object.

Choose the molecule with the strongest internal bond, (intra-, not intermolecular bond) ​
Verdich [7]

Answer:

A

Explanation:

The molecule with the strongest intramolecular bond is HF. Hydrogen fluoride is the answer due to the strong and highly electronegative nature of Fluorine.

  • Fluorine is the most electronegative element in nature.
  • When it combines with other substances, due to its electronegative property, it draws most of the electrons closest to itself in the bond.
  • This tendency and ability makes the shared electrons closer the fluorine in the bond.
  • The strong polarization that ensues confers a very strong covalent bond pair on the bond formed.

What element has 80 protons, 81 neutrons, 79 electrons?
Mariana [72]

Answer:

The element will be ^{161}_{80}X

Explanation:

Given that,

Number of proton = 80

Number of neutron = 81

Number of electron = 79

We know that,

The atomic number is equal to the number of proton.

So, the atomic number is 80.

According to atomic number,

The element will be mercury.

We need to calculate the atomic mass

Using formula of atomic mass

atomic\ mass=atomic\ number+number\ of\ neutron

Put the value into the formula

atomic\ mass=80+81

atomic\ mass=161

We need to find the element

Using atomic mass and atomic number

atomic\ mass\ number A=161

atomic\ number Z=80

So, the element will be

^{A}_{Z}X

Put the value of A and Z

Hence, The element will be ^{161}_{80}X
