Question

Number of electrons in hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, and oxygen.

Answer 1

The number of electrons in an atom equals its atomic number. Thus, hydrogen has 1, helium 2, lithium 3, beryllium 4, boron 5, carbon 6, nitrogen 7, and oxygen 8 electrons.

Step-by-step explanation:

The number of electrons in an atom is equal to the number of protons in the nucleus, assuming the atom is neutral and not an ion. Since the atomic number indicates the number of protons, it also reveals the number of electrons in a neutral atom. Here is a list specifying the number of electrons for the given elements:

• Hydrogen (H) has 1 electron.
• Helium (He) has 2 electrons.
• Lithium (Li) has 3 electrons.
• Beryllium (Be) has 4 electrons.
• Boron (B) has 5 electrons.
• Carbon (C) has 6 electrons.
• Nitrogen (N) has 7 electrons.
• Oxygen (O) has 8 electrons.

Answer 2

The number of electrons in hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, and oxygen are 1, 2, 3, 4, 5, 6, 7, and 8 respectively.
