Answer: Electronegativity difference of F and Cl: 1.0 and is covalent
Explanation:
The atomic number is the amount of protons in a nucleus, while the mass number is the protons plus neutrons.
Atomic number: 8
Atomic mass : 8+8 = 16
Answer: Atomic mass is 16, while atomic number is 8
Psoas major muscles, kidneys, inferior ribs, and lumbar transverse processes are demonstrated on AP abdominal projections.
<h3>What are AP abdominal projections?</h3>
The anteroposterior (AP) radiograph the patient in a supine position is the basis of the majority of plain-film examinations of the abdomen.
However, an upright-position film could also be helpful in patients with suspected bowel obstruction, also as to assess the air-fluid levels in the distended bowel.
This information also can be obtained on a film of the abdomen taken with the patient in the lateral decubitus position.
An AP supine projection is usually called a flat plate or KUB (because it includes the kidneys, ureter, and bladder)

Answer:
constant speed or a horizontal line is an rest
Explanation:
To find the number of neutrons.....
NEUTRONS = MASS NUMBER - ATOMIC NUMBER ( PROTONS)
NEUTRONS = 19 - 9
So this element has 10 neutrons
