An element is composed of only one type of atom. Each element on the Periodic Table is defined by the number of protons in its nucleus, which determines its unique chemical properties. Therefore, each element consists of atoms with the same number of protons.
Plastic is not an element. To be an element, a substance must have all the same type of atom. Once it has this, it can go on the Periodic Table. So, as plastic has many different types of atom in it, it's not an element.
The atomic number of an element gives its number of protons per atom. Sodium's atomic number is 11. Thus, sodium has 11 protons per atom.
The atomic number of an elemnt tells you how many protons are in the nucleus and therefore how many electrons thare are in a neutral atom. The mass number is the toal of protons and neutrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
No, sugar is not an element. To be an element, a substance must have all the same type of atom. A common sugar is Glucose, which has three atoms in it: 1 Carbon, 1 Hydrogen and 1 Oxygen in the arrangement C6H12O6 . This means that in one molecule of Glucose, there are 24 atoms. So, as sugar [Glucose] has many different types of atom in it, it's not an element.
No, talcom is not an element. To be an element, a substance must have all the same type of atom. Once it has this, it can go on the Periodic Table. So, as talcom has many different types of atom in it, it's not an element.
No, cornstarch is not an element. To be an element, a substance must have all the same type of atom. Once it has this, it can go on the Periodic Table. So, as cornstarch has many different types of atom in it, it's not an element.
No, insulin is not an element. To be an element, a substance must have all the same type of atom. Once it has this, it can go on the Periodic Table. So, as insulin has many different types of atom in it, it's not an element.
No, ferrule is not an element. To be an element, a substance must have all the same type of atom. Once it has this, it can go on the Periodic Table. So, as ferrule has many different types of atom in it, it's not an element.
Sulfur is a non metal element. There are 16 electrons in a single atom.
No, coca-cola is not an element. To be an element, a substance must have all the same type of atom. Once it has this, it can go on the Periodic Table. So, as coca-cola has many different types of atom in it, it's not an element.
5 valence electrons can be contained in 1 atom
No. An element is made up of only one type of atom. Water and oil are made up of many different types of atoms, so they do not form an element.
No. An element is made up of only one type of atom. Water and oil are made up of many different types of atoms, so they do not form an element.
No, paraffin is not an element. To be an element, a substance must have all the same type of atom. Once it has this, it can go on the Periodic Table. So, as paraffin has many different types of atom in it, it's not an element.
The molar mass is the sum of the atomic weights of atoms contained in the molecule.
It varies on the element of the atom.
