The particles that make up a sample of matter all have what?
The particles that make up a sample of matter all have mass, volume, and space between them.
What kinds of matter are present in any amounts?
In any given sample of matter, you can typically find elements, compounds, and mixtures present in varying amounts. These can include atoms, molecules, ions, and particles such as electrons and protons. Each type of matter contributes to the overall composition and properties of the sample.
What is the difference between an ion and an isotope?
an ion has a different number of electrons and an isotope has a different number of neutrons then listed on the Periodic Table or your sample
What is the number of subatomic particles in gold?
Mole is a unit of measurement of an amount of substance. I'll take particles to be atoms, for I assume the sample of Gold to be pure. In that case, the number of atoms in one mole of Gold will be the Avogadro constant, or 6.022142 × 1023.
What is the difference between the mass number and the atomic number of an element?
The difference between the atomic number and the mass number is that the atomic number is the number of protons in the nucleus of an atom of that element. The mass number is the total number of protons and neutrons in the atom.Atomic number = number of protonsMass number = total number of protons + neutrons
determine the subatomic particle ( electron, protons, neutron)?
For Example:- Calculate the number of protons, electrons, neutrons in Bromine with atomic number 35 and mass number 80. Hint: In order to answer this question you must recall the periodic properties and mole concept chapter in which you have done conversions regarding the number of moles, number of atoms, number of electrons, protons, and neutrons in a sample of given atomic number and mass number. Firstly, find the number of protons and the same number of electrons will be there and the sum of protons and neutrons form the mass number and you will get your answers. Complete step by step answer: Step 1: In this step we will find the number of protons of the given sample: Number of protons of a sample = Atomic Number of the element = 35 Step 2: In this step we will find the number of electrons of the given sample: Number of electrons of a sample = Number of protons = 35 Step 3: In this step we will find the number of neutrons of the given sample: Number of neutrons of a sample = (Mass number - Atomic Number) of the element Number of neutrons of a sample = 80 – 35 = 45 So, here we got our required values. The values are: No. of proton p = 35 No. of neutron n = 45 No. of electron e = 35 Note:The number of protons in the nucleus of the atom is equal to the atomic number (Z).The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

How many protons and electrons and neutrons does Ge-74 have?
The isotope Germanium -72 has 32 proton, 40 neutrons and 32 electrons. Two other stable isotopes are Ge-70 (38 neutrons) and Ge-74 (42 neutrons) both with the same numbers of protons and electrons as Ge-72 There is also a low percentage stable isotope Ge-73

How many protons and electric charges are in gold?
Since gold (AU) is the 79th element on the periodic table, it will always have 79 protons and electrons. There are 36 possible isotopes of gold so the electrons can fluctuate. If you happen to know the isotopic number, you can easily determine the number of electrons in your sample because these numbers are the same.
In a sample of pure copper all atoms have the same what?
In a sample of pure copper, all atoms have the same number of protons, which determines the element's identity.
How many protons and neutrons and electrons does the element gold have?
Gold (Au) has 79 protons, 118 neutrons, and 79 electrons.
What is the number of protons electrons and neutrons in sulfur?
The number of electrons and protons in a neutral sulfur atom is the same as the atomic number of sulfur, which is 16. However, the number of neutrons can vary: Four isotopes of sulfur occur naturally, with 16, 17, 18, and 20 neutrons. Some 95 % of the atoms in a typical sample have 16 neutrons per atom.
What is the subatomic particles of oxygen?
neutrons, protons and electrons. _________ The above is incorrect; those are atomic particles. Subatomic particles are what those particles are made of. Quarks and leptons are subatomic particles.
How many electrons are in an oxygen atom that hasan atomic number of 8?
The atomic number of an element _is_ the number of electrons in one of its atoms. Indeed, a sample of an element can be defined as any combination of atoms with the same atomic number. Oxygen is the element with atomic number 8. It is the element whose atoms have 8 electrons in their neutral state (and 8 protons).
Why Shouldn't every sample of matter have a negative charge Since all atoms have negatively charged electrons?
Not all atoms have negatively charged electrons. Atoms can also contain positively charged protons and neutral neutrons. The overall charge of an atom depends on the balance between its protons and electrons, leading to atoms having no net charge or a positive charge.
How many atoms are in iron?
The number of atoms in a sample of iron depends on the amount of iron present. One mole of iron contains 6.022 x 10^23 atoms.
