Which element in each pair has atoms with a larger atomic mass?
Carbon vs. Oxygen: Oxygen has atoms with a larger atomic mass. Sodium vs. Magnesium: Magnesium has atoms with a larger atomic mass. Phosphorus vs. Sulfur: Sulfur has atoms with a larger atomic mass.
How many neutrons are in atoms of chlorine?
There should be 17, since the atomic number is how many protons (of which there are the same amount of neutrons). However, if it is an unstable isotope, it would have more neutrons.
Do all of atoms of argon have same atomic number?
Yes
What is the atomic number of acetate?
The atomic number of an acetate ion (CH3COO-) is determined by the number of protons in its constituent atoms. Acetate contains two carbon atoms, three hydrogen atoms, and two oxygen atoms, totaling seven protons. Therefore, the atomic number of acetate is 7.
What is the atomic number of NH3?
NH3 is a compound, not an element. It does not have an atomic number. If you mean the number of atoms in the molecule the answer is 4: 1 nitrogen and 3 hydrogen. This is not the same as atomic number.
Where is the atomic number?
In the atoms on the periodic table the atomic number is the smaller of the two numbers, the other larger number is the mass umber
Which element in each pair has atoms with a larger atomic mass?
Carbon vs. Oxygen: Oxygen has atoms with a larger atomic mass. Sodium vs. Magnesium: Magnesium has atoms with a larger atomic mass. Phosphorus vs. Sulfur: Sulfur has atoms with a larger atomic mass.
How do atoms affect the type of elements?
The number of protons equal the atomic number; the electrons from the outer shell are involved in chemical reactions. The ionization energy and the electronegativity are also important characteristics of atoms. Atoms with a big mass become unstable etc.
An atoms atomic number is the number of what in its nucleus?
atomic number
What is the atomic number of atoms?
how do you find the atomic number for an element?
Is the atomic number the number of atoms it has?
The atomic number is equal to the number of protons.
Which has more atoms 10 moles of carbon or 10 moles of calcium?
10 moles of calcium has more atoms than 10 moles of carbon, as calcium has a higher atomic number and atomic weight compared to carbon. Each mole contains Avogadro's number of atoms, so the element with the larger atomic weight will have more atoms in 10 moles.
Are most atoms their mass number is the same as their atomic number?
No. In most atoms the mass number is at least twice the atomic number. A mass number that is the same as the atomic number would indicate a nucleus with no neutrons. Such a nucleus would be highly unstable except in the case of the hydrogen-1 nucleus, which consists of a single proton. In most other stable nuclei there are at least as many neutrons as their are protons. The mass number is the sum of the number of protons and the number of neutrons.
What does a atom have the same number of with electrons?
Because the atomic number is determined by counting the number of electrons circling the nucleus, (neutrons and protons). Only "stable elements" are given atomic numbers, as unstable ones loose and gain electrons. This is based on an atoms natural state.
How do you you work out the number of neutrons in an atom?
Atomic Mass minus atomic number
Which would you most expect to be an unstable atom?
An atom with an excess number of protons or neutrons relative to the number of electrons is more likely to be unstable. Additionally, atoms with a high atomic number (number of protons) tend to be less stable due to increased electromagnetic repulsion between the protons.
Which number is the atomic number?
the number of protons in an atoms nucleus is called atomic number
