awhat information in the periodic table lets you predict the number of electrons in an atom? 什么信息在周期表里让您预言电子的数量在原子?[translate]
An atom has an equal number of electrons and protons. 原子有相等数量的电子和质子。 This number became known as an element’s atomic number. 后来,这个数字被称为元素的原子序数。 Today, elements on the periodic table are arranged by atomic number, which gives a more accurate understanding of el...
Thegroupan element belongs to corresponds to the number of electrons in its outer shell. Group 1 elements have 1 outer shell electron, group 2 has two outer shell electrons, and group 0 has full other shells with 8 electrons ( or 2 for Helium ). How many elements are there in the Per...
1. The Elements and The Periodic Table(元素和周期表) The number of protons in the nucleus of an atom is referred to as the atomic number, or proton number, Z. The numbers of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom ...

In the periodic table of the elements, elements are arranged in a series of rows (or periods) so that those with similar properties appear in vertical columns. Elements of the same period have the same number of electron shells; with each group across a period, the elements have one more ...
While looking at xenon (Xe) on the periodic table, a student needs to find an element with a smaller atomic mass in the same group. Where should the student look? directly up This is how zirconium appears in the periodic table. Rounded to the nearest whole number, how many electrons are...
This is because each period represents a new energy level being filled with electrons. Therefore, the number of orbits/shells is the same within a period. Rate this question: 13. The most electronegative element on the periodic table is A. Lithium, Li B. Francium, Fr C. Astatine, ...

Each column on the table is called a group. All the elements in each group have the same number of electrons in their outer shell, also called valence electrons. Elements in the same group react with other elements in similar ways. Image source: By Lydia Kim Element Boxes Image source: ...
