Plzzz someone me study once you have completed the practice test, contact your instructor to complete your discussion-based assessment. you and your instructor will discuss what you have learned up to this point in the course to make sure you're ready to move on. take a minute to look over the grading rubric to become familiar with the criteria your instructor will use to grade you. think about any questions you still have about what you have learned. this conversation is a great time to ask questions.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
