Answer:
C. A neutron turns into a proton
D. An electron is ejected from the nucleus
Explanation:
- Beta decay is a type of the three major types of decays, others being alpha decay and gamma decay.
- During a beta decay the atomic number of an atom increases by one while the mass number remains the same.
- Beta decay may be classified as; an electron emission, positron emission and electron capture.
- <em><u>During electron emission an energetic electron is emitted from the nucleus, together with an antineutrino and a neutron in the nucleus turns into a proton. </u></em>
Answer:
Choice 'B'
Explanation:
Choice B => SCl₂ => 2 bonded pairs + 2 nonbonded pairs => 4 electron pairs => AX₄ parent => tetrahedral parent, but the shape is defined only by what's bonded to the central element that is, sulfur bonded to two Cl substrates. The electron pairs will assume positions in space (to minimize repulsion forces) like a regular tetrahedron (AX₄) but will have an AX₂E₂ geometry which is a Bent Geometry.
Suggest searching molecular geometry images online. Look for derivatives of AX₄ geometries. Example: H₂O (AX₂E₂ bent geometry; also a derivative of AX₄ tetrahedral parent geometry).
Answer:
The number of protons determines an element's atomic number (Z) and distinguishes one element from another. For example, carbon's atomic number (Z) is 6 because it has 6 protons. The number of neutrons can vary to produce isotopes, which are atoms of the same element that have different numbers of neutrons.
