What is a unique substance composed of atoms have the same atomic number?
I believe that is the definition of an element. true
What element is composed of atoms that all have the same atomic number?
All elements are composed of atoms that all have the same atomic number. If the atomic number is different then you have a different element. The number of neutrons can be different and you will have a different isotope of that element with a different mass. An example of an element that only has one isotope is fluorine.
What are elements composed of?
Elements are composed of atoms, which are made up of: protons,neutrons, and electrons. The number of protons in one atom of an element is equal to the periodic number of the element. If the element is in it's standard state(has no charge), then the number of electrons are equal to the number of protons. the number of neutrons can be determined by taking the atomic mass and subtracting the number of protons.For example 1 K (Potassium) atom has:19 Protons20 Neutrons19 Electrons
What element is composed of one proton and one neutron?
Hydrogen [H] has one proton. Its atomic number is 1 which is the number of protons. Also, the number of protons will always equal the number of electrons unless the element has a charge.
Why is pure gold classified as an element?
Because it cannot be broken down into a simpler substance by any substance and is composed of atoms that have the same number of protons in the nucleus. IN the case of gold that number is 79.

What does each different element represents?
an atom with a specific number of electrons { S.L.K ALL DAY} Each element is a pure substance composed of atoms which contain the same number of protons, which is the atomic number. The number of protons and atomic number are unique to each different element.
an element is a substance composed of atoms that all have the same number of protons.True or false?
True apex
What is a pure substance composed of atoms with the same number of protons and cant be broken down?
A chemical element.
What is a unique subtance composed of atoms having the same atomic number?
A element is a unique substance that is composed of atoms having the same atomic number. Energy is the ability to do work.
What element is composed of atoms that all have the same atomic number?
All elements are composed of atoms that all have the same atomic number. If the atomic number is different then you have a different element. The number of neutrons can be different and you will have a different isotope of that element with a different mass. An example of an element that only has one isotope is fluorine.
Is silver an element a compound a heterogeneous mixture or a solution?
silver is an element because, it is a pure chemical substance composed of atoms with the same number of protons.

Is the element is the smallest particle?
An element is a substance that is composed of atoms that are all of one type. Every atom, in turn, consists of at least two types of particles, protons and electrons. All of the atoms in a sample of an element have the same number of protons in them. It's a lot more complicated than this but this is a good start.
Are the number of electrons different from every atom of every element?
Each element has a different number of electrons. All atoms of that element have the same number of electrons. The number of electrons is the same as the number of protons.
What element is composed of one proton and one neutron?
Hydrogen [H] has one proton. Its atomic number is 1 which is the number of protons. Also, the number of protons will always equal the number of electrons unless the element has a charge.
