This is an easy problem to solve if you have a Periodic Table of Elements.
# protons + # neutrons = atomic number
3 + 4 = 7
The element with the atomic number 7 is Nitrogen.
As you already know the atom consists of protons, neutron and eletrons. The number of protons determins which chemical element it is, and on the periodic table of elements, we can see that the next element after lithium is beryllium.-An atom with 3 protons, 3 neutrons, and 3 electrons.- An atom with 3 protons, 5 neutrons, and 3 electrons
Lithium has 3 protons. The atomic number and the number of protons will be the same.
Beryllium has 4 protons, 5 neutrons, and 4 electrons
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.
Atomic number is the number of protons in the nucleus of an atom while the mass number is the sum of the protons and neutrons in the nucleus of an atom. for example lithium has an atomic number of 3 and a mass number of 7. Therefore lithium has 3 protons and 4 neutrons.
Protons neutrons and electrons
An atom of lithium isotope 6Li has 3 electrons and 3 protons and 3 neutrons.
Protons, Neutrons and Electrons.(:
Protons, neutrons, and electrons are the three basic parts of an atom. Protons have a positive charge, neutrons carry no charge, and electrons have a negative charge and orbit around the nucleus of an atom.
The mass number of an atom is the sum of its protons and neutrons. In this case, the atom has 3 protons and 4 neutrons, so the mass number is 3 + 4 = 7. Electrons do not contribute to the mass number as their mass is negligible compared to protons and neutrons.
It is 3 because you have to add the neutrons and the protons.
It is 3 because you have to add the neutrons and the protons.
Protons, Electrons, and Neutrons
they are protons, electrons and neutrons
As you already know the atom consists of protons, neutron and eletrons. The number of protons determins which chemical element it is, and on the periodic table of elements, we can see that the next element after lithium is beryllium.-An atom with 3 protons, 3 neutrons, and 3 electrons.- An atom with 3 protons, 5 neutrons, and 3 electrons
