Which of the following would not have the same number of valence electrons as the others boron aluminum gallium selenium?
Selenium would not have the same number of valence electrons as the others. Boron, aluminum, and gallium all have 3 valence electrons, while selenium has 6 valence electrons.
How many electrons are in a selenium ion?
Selenium typically has 34 electrons in its neutral state. To determine the number of electrons in a selenium ion, you need to know the specific charge of the ion. For example, a selenium ion with a charge of +2 would have 32 electrons, while a selenium ion with a charge of -2 would have 36 electrons.
How many electrons does the arsenic ion which has a -3 charge have?
The arsenic ion with a -3 charge has gained 3 electrons, giving it a total of 3 more electrons than the neutral arsenic atom. Arsenic typically has 33 electrons in its neutral state, so the arsenic ion with a -3 charge would have 36 electrons.
What element has 34 electrons?
The element with 34 electrons is selenium. Selenium has an atomic number of 34, which indicates the number of protons and electrons in a neutral atom of selenium. It is a nonmetal with chemical symbol Se and is commonly used in various industrial applications, including electronics and glass manufacturing.
What type bond will it be if calcium and selenium bond?
Calcium and selenium would likely form an ionic bond, with calcium losing 2 electrons to become a positively charged ion and selenium gaining 2 electrons to become a negatively charged ion.
What is the minimum number of electrons that would be expected to be in the valence shell of As in AsCL?
Arsenic (As) has five valence electrons, as it is located in group 15 of the periodic table. In AsCl, arsenic forms a covalent bond with chlorine (Cl), which has seven valence electrons. The minimum number of electrons in the valence shell of arsenic in this compound would still be five, as it does not lose any of its valence electrons despite forming bonds. Therefore, As would have five electrons in its valence shell in AsCl.

For example, a selenium ion with a charge of +2 would have 32 electrons, while a selenium ion with a charge of -2 would have 36 electrons.
What is the name for a selenium ion with 36 electrons?
When selenium gains two electrons, it becomes the selenide ion.
How many electrons does the arsenic ion which has a -3 charge have?
The arsenic ion with a -3 charge has gained 3 electrons, giving it a total of 3 more electrons than the neutral arsenic atom. Arsenic typically has 33 electrons in its neutral state, so the arsenic ion with a -3 charge would have 36 electrons.
How do you tell that there is 33 electrons in arsenic?
A neutral atom has equal numbers of positively charged protons and negatively charged electrons. The atomic number of an element is its number of protons. Arsenic's atomic number is 33, so atoms of arsenic have 33 protons. A neutral atom of arsenic would then also have 33 electrons.
How many electrons are in an atom with 33 protons and 42 neutrons?
That atom is Arsenic. It would have 33 electrons.
How many electrons does AS3- have?
Atomic number of arsenic is 33 so that would leave you with 36 electrons
What element has 34 electrons?

What type bond will it be if calcium and selenium bond?
Calcium and selenium would likely form an ionic bond, with calcium losing 2 electrons to become a positively charged ion and selenium gaining 2 electrons to become a negatively charged ion.
What is the Lewis Theory formula for Sr and Se?
The Lewis dot structure for strontium (Sr) shows it with two valence electrons, represented as Sr: ••. For selenium (Se), which has six valence electrons, the structure would be Se: •• •• ••. When forming a compound, strontium donates its two electrons to selenium, resulting in the formation of strontium selenide (SrSe), where Sr becomes a cation (Sr²⁺) and Se becomes an anion (Se²⁻). The resulting ionic bond reflects the transfer of electrons from Sr to Se.
What is the atomic radius of selenium if germanium's is 122 pm and arsenic's is 120 pm?
The atomic radius of selenium can be estimated to be approximately between 116 pm and 118 pm based on the trends in atomic radii going down a group in the periodic table. This is because atomic radius generally increases as you move down a group, so selenium's atomic radius would be smaller than arsenic's and germanium's.
