What else can I help you with?
Protons in the nucleus?
Protons are positively charged subatomic particles found in the nucleus of an atom. They determine the element's identity by the number of protons present, known as the atomic number. The number of protons also influences the chemical properties of the element.
What does the atomic number tells you?
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
What number represents the number of protons in an atom?
Protons are represented by the atomic number of an element. The number of protons is also the number of electrons. The number of protons is also represented in re Atomic Mass, which is the number of protons and the number of neutrons combined.
What is the atomic number also equal to?
The atomic number is equal to the protons and electrons of an element.
How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
How is hydrogen atom and radium atom different for each other?
Hydrogen atom has 1 proton and 1 electron; radium has 88 protons and electrons. Also radium is radioactive.
Astatine has 85 protons what is the atomic number?
The atomic number is the number of protons, so the atomic number of astatine is 85.
The atomic number of an atom or element describes the number of what?
The atomic number of an atom is also known as the proton number. it is, quite simply, the number of protons in the atoms nucleus - as an atom needs to be equally charged, it is also the number of electrons in an atom however, if an atom is radioactive this is not always true.
What does the atomic number on the periodic table tell?
The atomic number represents the number of protons. The atomic mass represents the number of protons + neutrons.
How many protons are in a lithium nucleus?
The atomic number of lithium is 3. Therefor there are 3 protons and neutron in the nucleus of lithium. Lithium also has 4 neutrons. atomic # = protons and neutrons neutrons = rounded atomic mass - atomic number Sources- 7th grade Acc. Science
The atomic number gives the number of what in an atomic nucleus?
Atomic Number It is thre position of the atom in the periodic table. It is the number of protons in the neucleud. It is the number of electrons in the neutally charged atoms. Atomic MASS it the total of the protons and neutrons in the atom.
How many protons does an element have when the atomic number is 8?
If an elements atomic number is 8, that means it also has 8 protons.
