what is the atomic number of an element quizlet?
11907
The atomic number is the the number of protons an element contains. The mass number is the sum of protons and neutrons in the nucleus of an atom. Atomic weight/ mass and Mass number. The mass number is the sum of both neutrons and protons.
1473876
The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element.
272678
The atomic number is equal to the number of protons in an atom's nucleus. Hydrogen's atomic number is 1 because all hydrogen atoms contain exactly one proton.
276803
The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.
954181
Neutral atoms of an element contain an equal number of protons and electrons. The number of protons determines an element's atomic number (Z) and distinguishes one element from another. ... The number of neutrons can vary to produce isotopes, which are atoms of the same element that have different numbers of neutrons.

1. The atomic number defines the identity of an element. 2. In an electrically neutral atom, the number of protons equals the number of electrons.
1380484
The number of protons in an atom is the atomic number of that element. That's also the number of electrons, since atoms are neutrally-charged. Finally, the difference between the atom's weight and the atomic number is the number of neutrons. This is an incredible answer.
37127
An atom is an element. The two words are synonymous, so if you're looking for the number of atoms in an element, the answer is always one, and only one.

['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.']
395040
The number of protons in one atom of an element determines the atom's _, and the number of electrons determines the Charge of the element. ... It also tells you the number of electrons in a neutral atom of that element. The atomic number gives the "identity" of an element as well as its location on the periodic table.

The number of protons in an atom is called its atomic number (Z). This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.
744467
Atomic number and mass number. The atomic number of an atom is the number of protons it contains. All the atoms of a particular element have the same atomic number (number of protons). The atoms of different elements have different numbers of protons.
1128377
If an element has 43 protons and 50 neutrons, its atomic number is 43. The element whose atomic number is 43 is technetium, or Tc.
186454
Since an atom of one element can be distinguished from an atom of another element by the number of protons in its nucleus, scientists are always interested in this number, and how this number differs between different elements. The number of protons in an atom is called its atomic number (Z).
856807
Atomic Number. The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.

The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. 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.
978721
The number of protons in the nucleus of an atom is its atomic number (Z). This is the defining trait of an element: Its value determines the identity of the atom. For example, any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have.
