4 0

Answer: Option (c) is the correct answer.

Explanation:

Gravity is defined as the attractive pull or force of attraction between the objects and the Earth.

For example, an apple falling from a tree to the ground represents that force of gravity has pulled the apple towards the ground.

Thus we can conclude that out of the given options, gravity is the attractive pull between any two objects.

Extend the aufbau sequence through an element that has not yet been identified, but whose atoms would completely fill 7p orbital

Thepotemich [5.8K]

Answer:

Number of electrons = 118

Electronic configuration: [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶

Explanation:

Given: A chemical element that has completely filled 7p orbital.

According to this, the principal occupied electron shell or the valence shell of such an element is 7p.

⇒ the principal quantum number (n) for the valence shell is 7.

∴ this element belongs to the period 7 of the periodic table.

Also, an element that has completely filled p-orbital belongs to the group 18 of the p-block.

Therefore, an element that belongs to the group 7 and period 18 of the periodic table, should have a completely filled 5f, 6d, 7s and 7p orbitals.

Therefore, the electronic configuration should be: [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶

And, the number of electrons = atomic number of radon (Rn) + 14 + 10 + 2 + 6 = 86 + 32 = 118.

Therefore, the given element has atomic number 118 and has the electronic configuration: [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶. Thus the given element can be Oganesson.

Is a covalent bond the same as an atomic compound? Please explain why and if not, please explain the difference.

dezoksy [38]

In an ionic bond, one atom essentially donate an electron to stabilize the other atom. A molecule bond is made when two or more atoms form a chemical bond, linking them together. The two types of bonds are ionic bonds and covalent bonds.

which of the following would increase the loudness of a sound? increase tension increase wavelength increase amplitude

andriy [413]

Answer : The correct option is, increase amplitude.

Explanation :

Amplitude : It is a measure of the size of sound waves.

The loudness of sound is depend on the amplitude of the sound wave. That means the more the amplitude, the louder will be the sound and the less the amplitude, the low will be the sound.

The loudness of sound does not depend on the tension and wavelength.

Therefore, the correct answer is, increase amplitude.
