Web27 Dec 2024 · Answer: An element's group number tells you how many valence electrons the element has. Explanation: In the periodic table, each element is placed in a specific location because of its atomic structure. The elements are arranged in rows, called a period. All of the elements in a period have the same number of atomic orbitals. WebFor elements in groups 6 and 7, the charge on the ion relates to the group number of the element in the periodic table. Oxygen is in group 6 of the periodic table. An oxygen atom …
WebThe one-one principle refers to the need to count each object in a group once, and only once. Children can be helped to do this by touching each object as they say the number name, this can help children to keep track of the objects that have been counted and ensure that they only count each object once. Web22 Mar 2024 · Group 1 indicates that the elements lying in that group have only 1 electron in its outermost orbit. In other words, group 1 elements have 1 valence electron.
