Which atom in the ground state has five electrons in its outer level and ten in its kernel?
The atom with five electrons in its outer level and ten in its kernel is a neutral sulfur atom. In its ground state, sulfur has 16 electrons distributed with 2 in the first energy level (kernel) and 2, 8, and 6 in the subsequent energy levels.
Which atom in the ground state has five electrons in its outer level and ten electrons in its kernel?
The atom with five electrons in its outer level and ten electrons in its kernel is boron. Boron has an atomic number of 5, with two electrons in the first energy level and three electrons in the second energy level.
The nucleus and all electrons in an atom except the valence electrons?
The nucleus of an atom contains protons and neutrons. Valence electrons are the outermost electrons in an atom that participate in chemical bonding. The electrons in the inner energy levels, excluding the valence electrons, are referred to as core electrons.
How does popcorn form with a chemical reaction?
Popcorn pops due to the sudden release of steam that is trapped inside the kernel when it is heated. The heat causes the moisture inside the kernel to turn into steam, creating pressure until the kernel finally explodes and turns inside out, forming the fluffy popcorn we enjoy eating. This process is a physical change, not a chemical reaction.
Is an oxygen atom have twice the mass of a sulphur atom?
No, an oxygen atom does not have twice the mass of a sulfur atom. An oxygen atom has a mass of approximately 16 atomic mass units (amu), while a sulfur atom has a mass of approximately 32 amu. Therefore, a sulfur atom has twice the mass of an oxygen atom.
