Ca is an atom give reason
WebA proton or neutron. How does the electric charge of a proton compare with the electric charge of an electron? It is equal and opposite. Since atoms are mostly empty space, why don't we fall through a floor we stand on? Electrons in one atom repel the electrons in another. What element has the lightest atoms? WebSolution. Verified by Toppr. Almost all of the mass in an atom is made up of the protons and neutrons in the nucleus. Protons are positively charged and neutrons have no charge on them. Because the nucleus is only made up of protons and neutrons it is positively charged. Was this answer helpful?

WebEvery subshell has a # of orbits s/p/d/f that can each hold 2 electrons each (one has the opposite spin of the other). The first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals. WebAn atomic radius is half the distance between adjacent atoms of the same element in a molecule. Measuring the atomic radii of chemical elements is a complicated task as the size of an atom is of the order of 1.2×10-10 m. The electron cloud forming the shell of an …
WebAug 14, 2024 · The first two electrons in lithium fill the 1 s orbital and have the same sets of four quantum numbers as the two electrons in helium. The remaining electron must occupy the orbital of next lowest energy, the 2 s orbital (Figure 8.3. 3 or 8.3. 4 ). Thus, the electron configuration and orbital diagram of lithium are: WebThe attractions between the protons and electrons of atoms can cause an electron to move completely from one atom to the other. When an atom loses or gains an electron, it is called an ion. ... But there is another type of bonding where atoms don’t share, but instead either take or give up electrons. This is called ionic bonding. This ...
