A different atom of iodine has a mass number of 128. What is this atoms relationship to the atom with a mass of 126
Mkey [24]

Answer:

The answer is below

Explanation:

They are isotopes. Isotopes are molecules that have the same atomic number but have different atomic mass because the number of neutrons is different.

Iodine has an atomic mass of 126 g and its atomic number is 53.

# of neutrons = 126 - 53 = 73

Its isotope has an atomic mass of 128 g its atomic number is also 53, but the number of neutrons is different.

# neutrons = 128 -53 = 75

12 Igneous rocks are formed by (1) sedimentation (2) fossilization (3) volcanic activity (4) freezing/thawing cycles​
inysia [295]

According to the research, the correct option is 3, Igneous rocks are those formed from a molten product from volcanic activity.

<h3>What are Igneous rocks?</h3>

They are rocks of high resistance, isotropy, brittleness and density that are created from the cooling and solidification of the magma, whether fragmented or compact, that form at erupting volcanoes, that is, this substance, made up of molten rocks and other elements, is found inside the planet.

When the cooling process takes place superficially and quickly, extrusive igneous rocks are produced, among which are obsidian and basalt, they usually appear after the eruption of a volcano, since the ejected lava solidifies.

Therefore, we can conclude that according to the research, the correct option is 3, Igneous rocks are those formed from a molten product from volcanic activity.

What would the result be of adding one proton to an atom​
GREYUIT [131]

Answer:Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium and thats your answer
