which of the following statements best describes the periodic table
a chart that organizes elements based on their atomic number
a chart that lists elements in alphabetical order
a chart that groups elements based on their melting points
a chart that shows the number of electrons in each element
The best statement that describes the periodic table is:
"A chart that organizes elements based on their atomic number."
you sure?
Yes, I am sure. The periodic table is a tabular arrangement of the elements, where they are organized based on their atomic numbers (number of protons in the nucleus) and their electron configurations. This arrangement allows patterns and trends in the properties of elements to be observed and studied.
which of the following is a physical property of matter
abilities of rust
ability to burn
ability to conduct electricity
ability to react with water
The physical property of matter among the options provided is:
The ability to conduct electricity.
Physical properties are characteristics that can be observed or measured without changing the chemical composition of a substance. The ability to conduct electricity is a physical property as it relates to the behavior of electrons in a material, rather than a chemical change or reaction.
what are these two changes have in common of rust forming on a metal gate snail growing its shell
both conserve Mass
both are chemical changes
both are only physical changes
both are changes in state
The two changes, rust forming on a metal gate and a snail growing its shell, have in common that:
Both are chemical changes.
A chemical change involves a rearrangement of the atoms and molecules in a substance, resulting in the formation of a new substance with different properties. In both cases, rust forming on a metal gate and a snail growing its shell, there is a chemical reaction occurring. Rust forms through the oxidation of iron in the presence of oxygen and moisture, resulting in the formation of iron oxide. In the case of a snail growing its shell, the snail's body absorbs calcium and other minerals from its environment to build and grow its shell, which is a chemical process.
just pick 2 out of the options i gave you
The two changes of rust forming on a metal gate and a snail growing its shell have in common that:
1. Both are chemical changes.
2. Both involve the conservation of mass.
what process transfers energy from the sun's core to its surface
convection
radiation
conduction
diffusion
