Which element is a metalloid with 4 valence electrons?
Germanium (Ge) Atomic Number- 32 Atomic Mass-72.59
This element has an atomic number lower than that of aluminum and one less valence election than the group 16 elements?
The element with an atomic number lower than aluminum is silicon, which has an atomic number of 14. Group 16 elements, like oxygen and sulfur, have 6 valence electrons, whereas silicon has 4 valence electrons.
How many valence electrons would an element with an atomic number of 14 have?
An element with an atomic number of 14, such as silicon, would have 4 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom, which corresponds to the group number of the element on the periodic table.
What elements have the same number of valence electrons as carbon?
It is silicon that has the same number of valence electrons as carbon. Silicon sits right below carbon on the periodic table.
How many electrons are in the valence shell of an atom with the atomic number of 14?
A neutral atom will have the same number of electrons as protons. A neutral atom with 14 electrons will therefore have 14 protons, as the negative electrons balance the positive protons. In an ion (atom with a charge), the number of electrons does not match the number of electrons.

What element has 6 valence electrons and 52 protons in the nucleus?
The element with 6 valence electrons and 52 protons in the nucleus is tellurium, which has the atomic number 52.
How do you find number of valence electrons?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
What elements have the same number of valence electrons as carbon?
It is silicon that has the same number of valence electrons as carbon. Silicon sits right below carbon on the periodic table.
What is the atomic number and number of valence electrons for each nucleic acid elements?
For carbon (C): Atomic number 6, 4 valence electrons. For hydrogen (H): Atomic number 1, 1 valence electron. For nitrogen (N): Atomic number 7, 5 valence electrons. For oxygen (O): Atomic number 8, 6 valence electrons. For phosphorus (P): Atomic number 15, 5 valence electrons.
How many valence electrons does a neutral atom of silicon have?
A neutral atom of silicon will have 4 valence electrons. The amount of valence electrons that a neutral atom will have can be found by the atoms group number in the periodic table.
How many electrons are in the valence shell of an atom with the atomic number of 14?
A neutral atom will have the same number of electrons as protons. A neutral atom with 14 electrons will therefore have 14 protons, as the negative electrons balance the positive protons. In an ion (atom with a charge), the number of electrons does not match the number of electrons.
How many electrons are in silicon?
Silicon has 14 electrons. It has an atomic number of 14, which corresponds to the number of protons and electrons in a neutral silicon atom.
What is total number of valence electrons for siH4?
A silicon atom has 4 valence electrons and each hydrogen atom has one valence electron, for a total of 8.
What element has 3 electron shells and 4 valence electrons?
Silicon. Electronic configuration [Ne]3s23p2
