Isotopes : a different number of neutrons. The chemistry is almost identical (mainly the reaction times are slightly different.
What else can I help you with?
How can there be two different atoms of iridium?
Isotopes are atoms of the same element with different numbers of neutrons in their nuclei, resulting in different atomic masses. This is how there can be two different atoms of iridium.
How is it possible for two different atoms to have the same atomic mass?
They would have to be atoms of the same element, and the same isotope of that element.
What are atoms that have the same element but different neutrons?
IsotopesThe number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.
A diatomic element may consist of two atoms of the same element or one atom of two different elements?
false
Two atoms are isotopes of the same element. Which of the following should be different for these two atoms?
Answer this question… The number of neutrons
Do some atoms have more or fewer protons than will other atoms of the same element?
No. The atomic number of an element is determined by its number of protons. If two atoms have different numbers of protons, they have different atomic numbers and are different elements.
If two elements have the same number of protons but different number of neutrons can they be atoms of the same element.?
Yes. If two atoms have the same number of protons then by definition they are the same element.
When two atoms of the element oxygen combine to form a molecule of oxygen the result is not a compound Why?
When two atoms of the element oxygen combine to form a molecule of oxygen (O2), it is still considered a pure substance because both atoms are of the same element. A compound is formed when atoms of different elements bond together. In this case, O2 is a molecule of an element rather than a compound because it consists of two atoms of the same element bonded together.
Which is made of at least two different types of atoms element molecule compoundmatter?
The answer could be molecule, compound and matter depending on the atoms of various element.
Is and atom and an element the samething?
No. Atoms are the building blocks of matter. Each element is composed of the same kind of atoms, according to their number of protons (atomic number). Molecules are composed of two or more atoms (they may be the same element or different elements), and compounds are composed of two or more kinds of atoms.
What are atoms of the same element but have different sums of protons and neutrons?
The Proton number defines the element, so there cannot be two atoms of the same element with different proton numbers, because they will be, by definition, different elements. Neutron numbers can differ though. When one element has different neutron configurations, these are called Isotopes.
How many different elements are in a oxygen molecule?
Oxygen is an element in its own right, so it only contains one element: oxygen.
