What else can I help you with?
The mass of any two atoms of the same element is always the same?
The masses of any two atoms of the same element are not always the same. Atomic mass (the mass you see on the periodic table) is just a weighted average of all of the weights of all of the different isotopes of an element.
Can atoms of different elements have the same number of protons be from the same element?
No. Each type of atom (element) has its own unique number of protons, which is called the atomic number. Atoms of the same element will always have the same atomic number (number of protons). Atoms of different elements will never have the same atomic number (number of protons).
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 pair of atoms form a pure covalent bond?
Two atoms of the same element and mass number.
How can I tell if a chemical reaction is balanced or not balanced?
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
How do we know if two atoms of the same element?
The number of protons.
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.
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.
What two atoms of the same element come together what do they form?
When two atoms of the same element come together, they form a molecule of that element. For example, when two oxygen atoms come together, they form a molecule of oxygen (O2).
Two atoms are isotopes of the same element which should be the same for these two atoms?
The number of protons in the nucleus is the same for both isotopes since they are of the same element. Isotopes of the same element have the same number of protons (which determines the element) but a different number of neutrons, leading to a difference in atomic mass.
Are two atoms that have the same number of protons the same element?
Yes. The number of protons defines the element.
Is The oxygen molecule made up of three atoms of the same element?
No, the oxygen molecule is made up of two atoms of the same element, oxygen.
Two Atoms of the same element when bonded form what?
Diatomic
Does molecule contain two atoms of the same element?
yes
What atoms are in a hydrogen molecule?
Molecular hydrogen has two atoms, both which are of the same element - hydrogen.
Why is the covalent between two atoms of the same element a non polar bond?
A nonpolar covalent bond between two atoms of the same element occurs when they have the same electronegativity, leading to equal sharing of electrons. This results in a symmetrical distribution of charge, making the bond nonpolar.
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.
