What is the atomic number of beryllium?
4Beryllium / Atomic number
How many electrons are in beryllium atom?
2,2Beryllium / Electrons per shell
How do you find the atomic number?
Atomic number = Number of protons For example, in a sodium atom, there are 11 electrons and 11 protons. Thus the atomic number of Na atom = number of electrons = number of protons = 11.
What atom has 4 protons and 4 neutrons?
beryllium
The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons.

How many atoms are in a element?
You can have one atom of an element, such as a single gold atom. Or you can have many atoms of an element, such as in a piece of pure gold. In the ordinary oxygen gas you are breathing, two oxygen atoms are bonded to form an oxygen molecule. In ozone, three oxygen atoms are bonded together.

What is atomic structure and periodic table?
The periodic table is a table that logically organize all the known elements. Each element has a specific location according its atomic structure. Each row and column has specific characteristics. Each row is called a period where all of the elements have the same number of atomic orbitals.
What are the 3 types of atom?
Atoms consist of three fundamental types of particles, protons, electrons and neutrons. Neutrons and protons have approximately the same mass and in contrast to this the mass of an electron is negligible. A proton carries a positive charge, a neutron has no charge and an electron is negatively charged.
How do you write the structure of an element?
How to Draw a Lewis Structure
- Step 1: Find the Total Number of Valence Electrons.
- Step 2: Find the Number of Electrons Needed to Make the Atoms “Happy”
- Step 4: Choose a Central Atom.
- Step 5: Draw a Skeletal Structure.
- Step 6: Place Electrons Around Outside Atoms.
- Step 7: Place Remaining Electrons Around the Central Atom.
