a. The atomic number gives the number of _____ in the nucleus.

검증된 단계별 안내
1
Understand the concept of atomic number: The atomic number of an element is a fundamental property that defines the element. It represents the number of protons in the nucleus of an atom.
Recall that protons are positively charged particles located in the nucleus of an atom. The atomic number is unique for each element and determines its identity.
Note that the atomic number is also equal to the number of electrons in a neutral atom, as the positive charge of protons is balanced by the negative charge of electrons.
To complete the statement, recognize that the atomic number specifically refers to the number of protons in the nucleus of an atom.
Write the completed statement: 'The atomic number gives the number of protons in the nucleus.'

Atomic Number

The atomic number is a fundamental property of an element that indicates the number of protons present in the nucleus of an atom. It uniquely identifies an element and determines its position in the periodic table. For example, hydrogen has an atomic number of 1, meaning it has one proton.

Protons

Protons are positively charged subatomic particles found in the nucleus of an atom. They play a crucial role in defining the identity of an element, as the number of protons determines the element's atomic number. For instance, an atom with two protons is helium, while one with six is carbon.

Nucleus

The nucleus is the central core of an atom, containing protons and neutrons. It is responsible for most of the atom's mass and is held together by strong nuclear forces. The arrangement and number of particles in the nucleus influence the atom's stability and its chemical behavior.
