Answer:

Atomic elements exist with a single atom as their basic unit.

H, F, and P are some examples of atomic elements.

H2, F2, and P4 are some examples of molecular elements.

Molecular elements have more than one atom in their basic unit.

Explanation:

Atomic element exists as the smallest particle of an element that can take part in a chemical reaction. They exist with a single atom as their basic unit. The atomic number of an element is the number of protons present in the atomic nucleus of the element. Atomic elements are usually monoatomic such as H, F and P.

Molecular elements are the smallest particle that are capable of independent existence and still retains the chemical properties of those substances. They are capable of independent existence because they are diatomic. The combination of atoms of the same type produces a molecule of an element such as H₂, F₂, and P₂.

Determine the nuclear composition (number of protons and neutrons) of the following isotopes. (a) chromium-52 protons neutrons (
madreJ [45]

Answer: a) chromium-52 :  protons = 24, neutrons = 28

selenium - 80 :  protons = 34, neutrons = 46

molybdenum-98:  protons = 42, neutrons = 56

xenon-132:  protons = 54, neutrons = 78

ytterbium-174 :  protons = 70, neutrons = 104

Explanation:

Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.

Thus, number of protons = atomic number

Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.

Mass number = Number of protons + Number of neutrons

a) chromium-52 :

Atomic number of Chromium is 24 hence number of protons  = 24

52= 24+ Number of neutrons

Number of neutrons = 28

b) selenium - 80 :

Atomic number of selenium is 34 hence number of protons  = 34

80 =  34 +  Number of neutrons

Number of neutrons = 46

c) molybdenum - 98 :

Atomic number of molybdenum is 42 is  hence number of protons  = 42

98 =  42 +  Number of neutrons

Number of neutrons = 56

d) xenon-132:

Atomic number of xenon is 54 hence number of protons  = 54

132 =  54 +  Number of neutrons

Number of neutrons = 78

e) ytterbium-174:

Atomic number of ytterbium is 70 and  hence number of protons  = 70

174 = 70 +  Number of neutrons

Number of neutrons = 104

Consider the reaction hc2h3o2(aq) h2o(l) → h3o (aq) c2h3o2–(aq). Which species is the conjugate acid?a. C2h3o2-(aq)b. H2o(l)c. H
saul85 [17]

The species that is the conjugate acid is HC₂H₃O₂(aq). The correct option is d.

<h3>What are conjugate acid?</h3>

Conjugates acids are those acids which are made when an acid donates a proton to a base according to Bronsted Lowry theory.

In other words, we can say that it is an acid with hydrogen ion. An example is  water (base) reacting with an acid to form the hydronium ion (conjugate acid).

Thus, the correct option is d, HC₂H₃O₂(aq).

How can we tell the distance sediments traveled due to erosion ?​
meriva

Answer:

more rounded the grains are the more they have been moved around

Explanation:

Generally – the more rounded the grains are the more they have been moved around (i.e. the longer the length of time or distance they have moved). Angular grains cannot have travelled far
