The table compares some characteristics of two atoms.

Charged Particles
Atom Number of Neutrons Mass Number
X 6 12
Y 7 13

Use the table to determine the number of protons for each atom. Then, choose the statement below that is true about the two atoms. (5 points)

Atom X and Atom Y are in the same row, but not the same family, on the periodic table.

Atoms X and Atom Y are in the same family, but not the same row, in the periodic table.

Atom X is in a column to the right of Atom Y in the periodic table.

Atom X and Atom Y occupy the same position in the periodic table because they are isotopes.

               Atom X and Atom Y occupy the same position in the periodic table because they are isotopes

Explanation:

            The table is as follow;

Atom/Charged particle                  # of neutrons                Mass #

                X                                              6                                12

               Y                                             7                                13

As we know the Mass number is the total number of protons and neutrons in the nucleus of an atom so,

Mass #  =  # of Protons + # of Neutrons

Solving above equation for protons,

# of Protons  =  Mass # - No. of Neutrons

For Atom X:

# of Protons  =  12 - 6

# of Protons  =  6

For Atom Y:

# of Protons  =  13 - 7

# of Protons  =  6

Hence, it can be concluded that the number of protons for both atoms are the same. Also, we also know that atoms having same no. of protons (atomic number) are the same elements.

Conclusion:

                  Atom X and Atom Y are two isotopes of Carbon with atomic number 12. One isotope has a mass number of 13 and have a chemical symbol of ¹³₆C while the other has mass number of 12 and with chemical symbol of ¹²₆C.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
