A covalent bond describes two atoms (most likely nonmetals) that share their valence electrons to satisfy the octet rule. Carbon and oxygen are both nonmetals, and they would share electrons with each other through a bond that is not polar enough to be considered ionic. The answer should be B

rodikova [14]

Answer:

Z=22.70

Explanation:

It is given that,

An element Z that has two naturally occurring isotopes with the following percent abundances as follows :

The isotope with a mass number 22 is 65.0% abundant; the isotope with a mass number 24 is 35.0% abundant.

The average atomic mass for element Z is given by :

Z=\dfrac{22\times 65+24\times 35}{100}\\\\Z=22.7

So, the average atomic mass for element Z is 22.70.

Finger [1]

Nonmetals which are located in the second row form pi bonds more easily than the elements situated in the third row and below. Actually there are no compounds or molecules known that forms covalent bonds to the noble gas Ne and Ar. Hence the other second row element which is Carbon, is the element that forms pi bonds most readily.

5. The amplitude of the ripples decreases as the circumference of the circle increases.

<h3>What is a wave?</h3>

A wave is a disturbance that moves energy from one place to another.

Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each travelling in a wave-like pattern at the speed of light. Hence, the statement is true.

As the disturbance moves outwards the energy it carries is spread over a larger and larger region called the wavefront. For example, the ripples in the water lie in a circle with an ever-increasing circumference. The amplitude of the ripples decreases as the circumference of the circle increases.
