A neutral atom must contain an equal number of electrons because it is a neutral atom.
A neutral atom with four electrons must contain four protons in the nucleus in order to maintain an overall neutral charge.
Berylium with an electron structure of 1s22s2 has 4 electrons.
An atom with an atomic number of four has four protons. The atomic number represents the number of protons in the nucleus of an atom.
The atom that has a Atomic Number of 6 in the periodic table - Carbon
Four.
A neutral atom with four electrons must contain four protons in the nucleus in order to maintain an overall neutral charge.
In a neutral atom, the number of electrons is equal to the number of protons. So, in an atom with three protons, it would contain three electrons. The number of neutrons does not affect the charge or number of electrons in the atom.
Neutral lithium atoms contain more neutrons than protons. A lithium atom typically has 3 protons in its nucleus, giving it an atomic number of 3, and it usually has 4 neutrons which adds to the mass number of 7.
Berylium with an electron structure of 1s22s2 has 4 electrons.
An atom with an atomic number of four has four protons. The atomic number represents the number of protons in the nucleus of an atom.

There are four protons in the nucleus of a beryllium atom.
Four.
The atomic number is the number of protons in an atom. In an electrostatically neutral atom, ie not an ion, it is also the number of electrons. Every single atom of an element will have the same number of protons, eg. Carbon always has six protons. This also helps us to understand the layout of the electron in an atom. Carbon has six so it arranges them into an inner group of two and an outer group of four, meaning it can have up to four bonds. Hope this helps.
A lithium atom contains three protons, three electrons, and usually four neutrons in its nucleus. The electrons occupy energy levels around the nucleus in a specific configuration.
That neutral silicon atom has four electrons in its valence shell.
