Your Question:
Which that these aspects has two electrons in its external p orbitals? A. Helium (He) B. Barium (Ba) C. Nitrogen (N) D. Silicon (Si) E. Sulfur (S)
A. Helium (He)
B) Atomic variety of Ba = 56
Valence Electron configuration = 6s²
C) Atomic number of N = 7
Valence Electron construction = 2s²2p³
D) Atomic variety of Si = 14
Valence Electron construction = 3s²3p²
E) Atomic number of S = 16
Valence Electron construction = 3s²3p⁴
Thus, silicon has actually 2 electron in its external p orbitals
Answer : The correct option is, Silicon (Si)
Explanation :
Element = Helium
Atomic number = number of electrons = 2
The digital configuration will be,
Element = Barium
Atomic number = number of electrons = 56
The digital configuration will certainly be,
Element = Nitrogen
Atomic number = variety of electrons = 7
The electronic configuration will certainly be,
Element = Silicon
Atomic number = number of electrons = 14
The digital configuration will certainly be,
Element = Sulfur
Atomic number = variety of electrons = 16
The electronic configuration will certainly be,
From the electronic configurations, us conclude that the facet silicon has actually two electrons in that valence "p" orbit or outermost "p" orbitals.
You are watching: Which of these elements has two electrons in its outer p orbitals?
Hence, the correct option is, Silicon (Si)
Answer is: zirconium (Zr).
Atomic number of zirconium (Zr) is 40, which means it has 40 protons and 40 electrons.
Electron configuration of zirconium atom:
₄₀Zr 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d²5s².
Zirconium has four valence electrons, the is in team 4 and duration 5.
Zirconium is a lustrous, grey-white, strong transition metal.
Charge= -2
Explanation:
In an atom, are included three SUBATOMIC corpuscle viz: proton and also neutron found in the nucleus, electrons surrounding the nucleus. Proton contain the confident charge of one atom while electron contain the an adverse charge of an atom. The number of protons and electrons in an atom identify the charge of an ion (charged atom). Also, the atomic mass or mass number of that atom is obtained by adding the number of protons + variety of neutrons.
In this case where the variety of protons and number of neutrons space 16 and also 17 respectively, the massive no. Or atom mass is 17 + 16 = 33.
Also, due to the fact that two electron are acquired by this atom, it means the electron numbe, which is normally equal come the proton number in a neutral atom, will certainly be boosted by 2. Hence, the electron number will be 18 in this case.
The charge of the atom= no. Of proton - no. Of electron = 16 - 18 = -2.
Explanation:
Atomic number of magnesium is 12 and its electronic circulation is 2, 8, 2. To obtain noble gas construction it is vital for the magnesium atom to lose two valence electrons and also therefore, it develops
On the other hand, atomic variety of oxygen atom is 8 and its electronic distribution is 2, 6. To acquire noble gas configuration it requirements to gain two electrons. And, on gaining the electrons it creates
Hence, once both magnesium and also oxygen ions chemically integrate with each other then it forms the link magnesium oxide (

This is due to the fact that magnesium transfer its 2 valence electrons to the oxygen atom and also due come the development of opposite dues on these atoms they acquire attracted towards each other.
I think it would be Calcium because the below levels walk 2, 8, 8 so include those and then 2 an ext to do 20
Magnesium and also calcium belong come the 2nd group i. E. Alkaline planet metals. Castle are well-known as planet metals since they room extracted indigenous the earth. They are an extremely reactive elements. Their reactivity boosts when us go from top to bottom due to the fact that the outermost electron goes ƒᴀʀтher from the cell core i. E. Atom radius rises so less energy is necessary for its removal.
