The atomic number of an element is equal to the number of protons an atom has. Each element has a characteristic atomic number that defines it.Answer and Explanation: Iron has an atomic number of 26. This means that iron has 26 protons. The atomic number can be located using the periodic...
- The first shell can hold 2 electrons. - The second shell can hold 8 electrons. - The third shell has 7 electrons. - Therefore, the total number of electrons is calculated as: 2+8+7=17 electrons 3. Determine Atomic Number: - For a neutral atom, the number of electrons is equal ...
An atom that has more protons than electrons is called a cation. Ions are charged atoms or combinations of atoms. When an atom loses one or more...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer your...
What changes when an ion is made from an atom?A:the number of electrons onlyB:the number of neutrons onlyC:the number of protons onlyD:the number both of protons and of neutrons 相关知识点: 试题来源: 解析 A 考查实际运用。A. 仅电子数量(变化),B. 仅中子数量(变化),C. 仅质子数量(变化...
The atomic number of an atom is equal to the number of protons found in the atom's nucleus. The mass number of an atom is the total number of protons and neutrons in the nucleus of the atom. Thus, the atomic number is also a contributing factor in the ...
On the most basic level, electronegativity is determined by factors such as the nuclear charge and the number/location of other electrons present in the atomic shells. The nuclear charge is important because the more protons an atom has, the more “pull” it will have on negative electrons. ...
of the mass of a single carbon-12 atom, at rest. The protons and neutrons of the nucleus account for nearly all of the total mass of atoms, with electrons and nuclear binding energy making minor contributions. Thus, the numeric value of the atomic mass w...
What is the maximum number of electrons it can have in an atom? View Solution What is the maximum number of electron that can be accommodated in a shell? Write the formula. View Solution In a hydrogen atom, a Bohr's orbit has diameter of about 4. 232A. What is the maximum number ...
Since an atom contains equal number of protons and electrons, it has no overall charge: the positive charges on all the protons are exactly balanced by the negative charges on all the electrons. But sometimes an atom can gain or lose an electron to become what's called an ion. If it ...
A Neutron is neutral and has no charge. 15 How do Electrons influence an element's chemical behavior? The configuration and number of Electrons in outer shells determine reactivity. 14 Where can you find Electrons in an atom? Electrons orbit around the nucleus in specific energy levels. 9 Why...
