Number of moles = mass / molar mass, so the answer is the one with the greatest molar mass. This is plutonium.
This element is plutonium.
Every element in the periodic table contains at least two atoms joined up except for Hydrogen (H).
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.
Kevlar does.
O2 is a diatomic gas, it has only one type of atoms so it is an element while a compound contains at least two types of atoms or elements as HCl .HF , H2O.
The answer could be molecule, compound and matter depending on the atoms of various element.
Every nucleus of every element contains at least 1 proton. Every element except hydrogen also contains neutrons.
An atom is the smallest part of an element that still has all of its properties, while a molecule is a group of atoms bonded together. An atom is the smallest particle of an element that has the properties of that element. A molecule is composed of two or more atoms covalently bonded. The atoms can be the same element, like hydrogen gas, H2, or the atoms can be different elements, like carbon dioxide, CO2, which is not only a molecule, but is also a compound because it contains at least two different elements.
... atoms of at least one other element than the one that is split.
An oxide always has at least one oxygen atom as well as at least one atom of a different element.
No, All elements are made up of a single kind of atom. All of the atoms of an element have the same number of protons. The atoms may differ by having more or fewer neutrons but the number of protons determines the kind of atom.
A compound has at least two different types of atoms. A pure element has only one type of atom.
A Diatomic molecule contains two atoms.A Homoatomic molecule contains two or more atoms of one element.A Hetroatomic melocule contains at least two atoms of two or more elements.
