Is an atoms number of protons is always the same as its number of valence electrons?
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
What element is composed of one proton and one neutron?
Hydrogen [H] has one proton. Its atomic number is 1 which is the number of protons. Also, the number of protons will always equal the number of electrons unless the element has a charge.
What subatomic particle number determines the identity of an element?
The number of protons, which is the atomic number of an element, determines the identity of an element.
Which neutral atom of an element has 1 unpaired electron?
I'm pretty sure its hydrogen, since the is only 1 proton and 1 electron.
When neutral what element has 36 electrons?
I assume by neutral, you mean atoms rather than ions. This means we have the element with a proton number of 36 which is the noble gas krypton.
How many electrons in an element with one proton?
The number of PROTONs and the number of ELECTRONs are always equal in a neutral atom. Therefore an element with one PROTON will have one ELECTRON and that element will be called Hydrogen.
What is equal to the number or proton in an atom found on the periodic table?
Atomic number of an element = Number of protons = Number of electrons.
Subatomic particle that defines the element?
The subatomic particle that defines the element is the proton. The number of protons in the nucleus of an atom determines the element's atomic number, which differentiates one element from another on the periodic table.
How many proton and electrons does the element magnesium have?
Magnesium has an atomic number of 12, therefore it has 12 protons, and therefore 12 electrons.
Do isotopes of an element have the same atomic number?
They have the same number of protons (and electrons) - so proton number. They have a varying number of neutrons - Mass number. Proton number and Atomic number mean the same things, so Isotopes of an element have the same atomic number.
When a proton has an atomic number of 24 what is it electron number?
There is NO proton with atomic number 24.An atom with atomic number 24 has 24 protons AND 24 electrons, known to be element Chromium (Cr)
Is an atoms number of protons is always the same as its number of valence electrons?
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
What is the importance of proton number in an atom?
The proton number of an atom determines what element it is an atom of. That is, it determines the chemical properties of the atom. It does this because the charge on the neutron is neutral, which means that the total charge of the nucleus is equal to the proton number, which it turn means that the number of electrons in the uncharged atom is equal to the proton number. And that in turn determines which electron shells will be filled and what valence electrons available. In this context, the proton number of the nucleus is the atomic number of theelement.
Which subatomic particle identifies an atom of a particular element?
It's the count of one of the subatomic particles in the nucleus, the proton, that is significant in this regard. For example, an atom is hydrogen if and only if it has one proton in its nucleus. It is neon if and only if it has ten protons in its nucleus.
How do you calculate protons and electrons?
Refer to the Periodic Table to find an element's atomic number. This gives the proton number of that element, as well as the number of electrons (assuming the atom is neutral). For example, carbon has an atomic number of 6, which means it has six protons, and - when neutral - 6 electrons, as well.
Is the number of proton the same as that of electrons in atoms?
In an element: yes Ions vary, like Ca+2 has two less electrons than protons.
What is the number of proton in the element iron?
In the element iron there are 26 protons. In the core there are 30 neutrons as well, and 26 electrons are circling around this core.
