What is the atomic number and what does it tell you about the number of protons in an atom?
The number of protons in an atom is the atomic numberThe number of protons is equal to the atomic number of an atom. It is very important in knowing the number of electrons that surround the nucleus of an atom. In an atom, the electrical charge is neutral, due to the equal number of positive (protons) and negative (electrons) charges. The atomic number represents the protons in an atom and also identifies the element. Hydrogen has one proton. No other atom has just one proton. Heluim has two protons and no other element has only two protons. Lithium has three protons and so on. The atomic number is equal to the number of protons in the nucleus, and for neutral atoms, it is the same as the number of electrons. In an attempt to keep atoms and ions from getting confused with one another, it is best to think of atoms as always being electrically neutral and ions should be considered charged positively or negatively depending on whether electrons are gained or lost by an atom during the chemical combination of atoms in forming substances such as water, salt and rust found on metals. Protons in atoms and ions are always the same for a specific atom.Every element has a unique atomic number, and so each element's identity is determined by the number of protons in its nucleus.However, the same element can have different numbers of neutrons in its nucleus. Two atoms of the same element with two different numbers of neutrons in the nucleus are called isotopes. Also, note that if an atom is not charged (neutral), then the number of protons must equal the number of electrons, and so the atomic number is also equal to the number of electrons in a neutral atom of each element.However, if the atom is charged (and therefore called an ion), it will have a different number of electrons orbiting it. If the number of electrons is less than the number of protons, it will be a positively charged ion, and the charge will equal the difference between the number of electrons and protons. The same is true if it has more electrons than protons, except now the charge will be negative.Look under the Web Links below this answer for a periodic table. The number listed for each element is its atomic number. Also see the Related Questions links for more information about the number of protons, neutrons, and electrons in an atom.
What piece of information would best help to identify the element?
The atomic number of the element would be the most helpful piece of information for identifying it, as each element has a unique atomic number that corresponds to the number of protons in its nucleus.
What is the diatomic nitrogen molecule best described as?
The diatomic nitrogen molecule (N2) is best described as a colorless, odorless, and tasteless gas formed by two nitrogen atoms covalently bonded together. It is the most abundant gas in Earth's atmosphere and is essential for many biological processes, including plant growth.
Why is this that most chlorine atoms contain 18 neutrons?
It would have 17 electrons. All chlorine atoms would have 17 electrons because they are electrically neutral, which means that number of protons (of charge +1) would be equal to number of electrons (of charge -1). This is true for all isotopes of chlorine.
Which best describes john Dalton's observations of elements in any given compound?
Dalton discovered that the atoms that combine to form compounds are distinguished from one another by their atomic weights. He also learned that all atoms of a given element are identical.
How are atoms best described?
Atoms are the basic building blocks of matter that consist of a nucleus made up of protons and neutrons, with electrons orbiting around the nucleus. They are the smallest unit of an element that retains its chemical properties. Atoms are characterized by their atomic number (number of protons) and atomic mass (sum of protons and neutrons).
What best describes the relationship between the atoms described below?
They each contain 1 neutron
Is atomic number the number of electrons in an atom?
Technically it is the number of protons, which is the same as the number of electrons in a neutral atom. But since most atoms can either gain or lose electrons to form ions it is still best to base atomic number on the protons.
Covalent bonds can best be described as a of electrons.?
Covalent bonds can best be described as a sharing of electrons between atoms.
Daltons model of an atom is best described as?
Dalton's model of an atom, proposed in the early 19th century, viewed the atom as a solid, indivisible sphere. He believed that atoms of different elements had different masses and sizes, and that they combined in simple whole number ratios to form compounds. However, this model was later replaced by more advanced atomic models that better explained the behavior of atoms.
Covalent bonds can best be described as a what of electronts?
Covalent bonds can be best described as a sharing of electrons between atoms. This sharing creates a stable arrangement of electrons in the outer energy levels of the atoms involved.
What best describe electrons located in atoms?
This is the atomic orbitals theory.
What unit would be best used to count the number of silver atoms in a spoon?
The unit used to count the number of silver atoms in a spoon would be the mole. A mole is a unit representing a specific number of atoms (Avogadro's number), which allows for convenient measurement and comparison of the amount of substance at the atomic or molecular scale.
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
When atoms or molecules gain or lose electrons they can be best described as what?
When atoms or molecules gain or lose electrons, they are best described as becoming ions. Ions are charged particles that are formed through the process of gaining or losing electrons.
Is the statement An atom consists of a dense nucleus surrounded by a cloud of electrons best described as a law or hypothesis or a theory?
The statement "An atom consists of a dense nucleus surrounded by a cloud of electrons" is best described as a theory in the field of atomic structure. The atomic theory explains the structure of atoms based on experimental evidence and scientific principles.
How are atoms and elements similar?
Atoms of the same element are identical. there protons all have the same number but there can be variations between the number of electrons,neutrons and atomic mass.By:Matthew Ray Tan Caseñas
