A metal containing 3 valence electrons and 13 protons in its atom is what metal?
The fact that the element has 13 protons indicates that this element is aluminum. The number of protons in the nucleus is the atomic number of an element. Every element has its own unique atomic number that never changes in ordinary chemical or physical reactions.
What makes one atom or element different than another?
Different atoms either have a different number of protons(which makes them different elements) or a different number of neutrons (which makes them isotopes of the same element).For example, hydrogen has one proton (and usually no neutrons) while helium has two protons (and usually two neutrons). However, hydrogen with one proton and two neutrons is called tritium(3H) while helium with two protons and one neutron is called helium-3 (3He).
The lines in the bright line spectrum of an atom are due to what?
The atomic line spectrum comes from the emission of atoms of different elements that are in an excited state. Each element has its own unique atomic emission spectrum.
What makes an element unique?
Every atom has a certain number of protons, neutrons, and electrons. Different elements have different amounts of these. Particularly, different elements have different numbers of protons. For example, if an atom only has 1 proton it must be hydrogen.
What is an chemisty element?
A chemical element is a substance with only one type of atom in it (e.g. only carbon atoms). The known chemical elements are arranged on the Periodic Table of the Elements. Every element has it's own chemical symbol, which is used as a scientific shorthand for quick elemental notation (e.g. Carbon = C, Promethium = Pm).
What element has an atomic number of 7?
The element with an atomic number of 7 is nitrogen. It is a nonmetal that is essential for various biological processes and is commonly found in the Earth's atmosphere.
What atom or isotope of an element has an atomic mass of 26 charge of 3 13 protons 13 neutrons and 10 electrons?
The number of protons identifies this element as aluminum, which has an atomic number of 13. The number of protons is an element's atomic number on the periodic table. Every element has its own unique atomic number which defines it as that element.
Is the atomic number?
Atomic number is the number of protons in the atoms of a particular element. Each element has its own unique atomic number.
Name for the atomic number?
The atomic number is the number of protons in the atomic nucleus of a particular element. Each element has its own unique atomic number.
What elements have atomic number?
All chemical elements have atomic numbers.
If the atomic number of element D is 20 then what is the atomic number of element R?
34
What same elements have the same atomic number?
though your question is unclear, each element has its own atomic number. every sample of Sulfur (S) that exists has the atomic number of 16. No different elements share the same atomic number.
Does each element have its own atomic number?
Yes. The atomic number of an atom is the number of protons in its nucleus, which actually defines which element it is.
The atomic number is the same as?
The atomic number is the number fo protons in an atom's nucleus. It decides the element's position on the periodic table, as well as what the element is. No two elements have the same atomic number. As soon as the atomic number, or number of protons, changes, the element itself actually changes into a new element.
What is the atomic number for the element hydrogen chloride?
Hydrogen chloride is not an element; it is a compound and has no atomic number!
Which subatomic particle determines the properties of an element?
The number of protons in the atomic nucleus determines the properties of an element. Every element has its own unique number of protons, called its atomic number, which is displayed on the periodic table. The elements are arranged in order of increasing atomic number on the periodic table.
What makes atoms of different elements different from one another.?
The number of protons in the nuclei of their atoms. This is the atomic number of an element and each element has its own unique atomic number.
