On the left side.
oxygen is an element on the Periodic Table of elements. This means that oxygen is an atom which could bond with another element covalently to form a molecule
There is none, but a neutral atom is called a neutron. There is no neutral element.
A transition element of f-block Thorium has 90 electrons in natural state, it is a Radioactive element.
Hydrochloric Acid (HCl) is not an element on the periodic table, it is a molecule.
Helium
Nitrogen is the 7th element in the Periodic Table. It has 7 electrons and protons.
The element Neon
No, the other way 'round. An element exists at the single-atom level. A molecule is made of more than one atom. It can be a single element(hydrogen is more stable if 2 form a molecule H2), or can be hugely complex and made up of many different elements.
The groups in the periodic table tell you what each element within them will react with, the number of valance electrons the element has, and what family it is in.
Well the atomic mass is the number of electrons, neutrons and protons in the molecule for example with hydrogen there are one electrons one neutron and no protons. this is because it is the first element on the periodic table.
Elements on the periodic table are arranged according to the number of protons in their nucleus, also known as their atomic number.54th element on the periodic table is Xenon.
35, 16, and another number. S=Sulfur off the periodic table.
