What else can I help you with?
Where on the periodic table can you find an element that has the same chemical properties as another element but is more massive than an elementl?
Down in any group of the perodic table.
What element is most active out of Be Mg Sr Ca?
Barium (Ba) is the most electropositive element. In general, electropositivity (reverse of electronegativity) decreases across the rows of the periodic table and increases down the columns.
What is the atomic number and its trend on the periodic table?
The atomic number of an element is the number of protons in the nucleus of one atom of that element. In general, atomic numbers increase as you move to the right and down in the table.
Do the elements in the periodic table have the same mass?
No! The mass of one atom of each element increases as you move down and to the right on a periodic table. The mass of an atom of a particular element is called its atomic mass.
What is a substance that can't be broken down into a simpler substance by chemical means?
An element is a substance that cannot be broken down into a simpler substance by chemical means. Each element is represented by a unique symbol on the periodic table.
What is a pure substance and will not break down on a periodic table?
an element
Where on the periodic table can you find an element that has the same chemical properties as another element but is more massive than an elementl?
Down in any group of the perodic table.
What is the name of the element that is broken down into simplest substances?
an element which is then broken down into: protons, neutrons, and electrons. for a list of elements see a periodic table
What element is most active out of Be Mg Sr Ca?
Barium (Ba) is the most electropositive element. In general, electropositivity (reverse of electronegativity) decreases across the rows of the periodic table and increases down the columns.
Is there blood in the peridoic table?
No. Every substance in the Periodic Table is an element - that is, a substance that cannot be broken down into a simpler form. For example, H2O is made of the elements hydrogen and oxygen. Blood, however, is a homogeneous mixture, not an element, and can be broken down into simpler substances, so it does not belong on the Periodic table.
What is the atomic number and its trend on the periodic table?
The atomic number of an element is the number of protons in the nucleus of one atom of that element. In general, atomic numbers increase as you move to the right and down in the table.
Do the elements in the periodic table have the same mass?
No! The mass of one atom of each element increases as you move down and to the right on a periodic table. The mass of an atom of a particular element is called its atomic mass.
What is a substance that can't be broken down into a simpler substance by chemical means?
An element is a substance that cannot be broken down into a simpler substance by chemical means. Each element is represented by a unique symbol on the periodic table.
Is hydrogen a element compound or mixture?
Hydrogen is an element, number 1 on the table of elements actually.
What is uranium an element or compound?
It is an element. It appears in the periodic table with atomic number 92. It cannot be broken down into simpler substances using chemical means.
Can helium be broken down into a simpler substance?
Helium is a chemical element and is the simplest and lightest noble gas in the periodic table. It cannot be broken down into simpler substances by chemical reactions, as it consists of only helium atoms.
How many protons an elements has based on its place on its periodic table?
The number of protons in an element is equal to its atomic number, which is its position on the periodic table. For example, hydrogen, which is the first element, has an atomic number of 1 and therefore has one proton. As you move down the periodic table, each successive element has one more proton than the previous element. Thus, the atomic number directly indicates the number of protons in the nucleus of an atom of that element.
