Most metals are silvery white or gray reflective. You could expect Dubnium is too. A chemical element, symbol Db, atomic number 105. It was http://www.answers.com/topic/synthesize and identified unambiguously in March 1970 at the heavy-ion linear accelerator (HILAC) at the Lawrence Radiation Laboratory, Berkeley, University of California. The discovery team consisted of A. Ghiorso and colleagues. See alsoperiodic-table.
Look at the chemical formula. NaCl is one atom of Na and one atom of Cl. NaCl is your common table salt. Water H2O, is two atoms of Hydrogen and one atom of Oxygen, H and O. Here is a link to a good table of elements
this is because an element is sometimes never radioactive but one may be made just to be radioactive this is because an element is sometimes never radioactive but one may be made just to be radioactive
For a neutral atom they must have equal numbers of protons and electrons. The atomic number is the number of protons in an atom of an element. Find the atomic number by looking at the periodic table of elements.
At the center of an atom we will find the nucleus of the atom. There, we'll find protons and neutrons (except "common" hydrogen, which has a single proton for a nucleus). For more information on the nucleus of the atom, see the related question below. The dense part of the atom which can usually be 'called' its center is the nucleus - which has charged (electrical) protons and neutrons (electrically neutral) those are surrounds by look-like 'cloud' called electrons.The center core of an atom is called the nucleus. It consists of the neutrons and protons.
The terms element and compound are used to identify pure substances.
A plutonium atom has 92 electrons and 150 protrons. It has three shells and is a very unstable element.

If you know how many protons the atom has, then that can tell you what element from the periodic table is classifying the atom.
you cant see an atom!
To determine the number of electrons in an element, you can look at the atomic number of the element on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
Depends on the element. Every element has a unique number of protons within the nucleus of each atom. For example, Hydrogen atoms all have one proton in the nucleus. Take a look at the atomic number of an element on the period table. This number tells you how many protons are located in each atom of the material.
an "element" can be divided until it reaches a single atom. But a "molecule" can only be divided until it is a single molecule. For instance, water, H2O, is usually present in the millions to look like water. However, if you divide it up into smaller and smaller portions, say halves, you can only divide it until you have 2 Hydrogens and 1 Oxygen. If you divide it further, it is no longer water. It will become something else.
It's the number of protons in core of atom ----- Depends on what element you are talking about, there are plenty of table of elements on the web, look into that
To determine the number of electrons in an element, you can look at the element's atomic number on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
look at the peridodic table.
