What else can I help you with?
Is it true or false that characteristic properties of elements do not depend on the amount of material present in a sample of the element?
True. Characteristic properties of elements, such as melting point, boiling point, density, and chemical reactivity, do not depend on the amount of material present in a sample of the element. These properties are unique to each element and remain constant regardless of the quantity of the substance.
How many electrons do copper have?
In a chemical element, there are the same amount of protons as there are electrons. In the chemical element copper, there are currently 29 electrons.
What blood study determines the amount of pigment present in Red Blood Cells?
A blood study called a complete blood count (CBC) can determine the amount of pigment present in red blood cells. This test measures parameters like hemoglobin and hematocrit levels, which reflect the amount of pigment (hemoglobin) in the red blood cells. Abnormal levels can indicate conditions like anemia or polycythemia.
What trace element is needed to make hemoglobin for oxygen transport?
Iron (Fe) is a trace element that contributes to the composition of the protein called Hemoglobin. Hemoglobin is carried in red blood cells. Hemoglobin's main job is to carry oxygen throughout the body. So, when a person does not have enough iron in their body, they will begin to feel drowsy and fatigued, because the proper amount of oxygen is not available. This condition is called Anemia.
The amount of an element present does not affect the elments what?
The amount of an element present does not affect the element's identity. Each element is defined by the number of protons in its nucleus, known as its atomic number. This remains constant regardless of the quantity of the element present.
What chemical element are present in guanine?
Guanine is a nitrogenous base found in DNA and RNA. It contains the chemical elements carbon, hydrogen, nitrogen, oxygen, and a trace amount of nitrogen.
Element present in seafood?
A small amount of mercury can be found in some fish
What is the chemical substance present in maximum amount in an animal cell?

What does the chemistry term abundance mean. Please answer in small words?
"Abundance" in chemistry refers to how much of a particular element or chemical is present in a sample or environment. It indicates the relative proportion or quantity of a substance compared to other substances in a given context.
Which element is present in the largest amount in rocks and minerals?
Oxygen is the element present in the largest amount in rocks and minerals. It is a major component of most minerals, forming the backbone of silicate minerals that make up the majority of the Earth's crust.
By chemical analysis what nutrient is present in highest amount in most foods?
Water
