Which element has the highest electron affinity among halogens? Which contributes more to an atom's mass: electrons or protons? What is the most common isotope of oxygen? Which of the gases H_2, SF_6, CO_2, He, N_2, H_2O will have the highest or largest effusion rate?
(a) What is the atomic number of the element ? (b) State whether element Z is a metal or a non-metal (c) What type of ion (if any) will be formed by an atom of element Z ? Why ? (d) What is special about the outermost electron shell of the atom of this element ?
To solve the question, we need to identify an element that has a total of two electron shells and three electrons in its valence shell. Here’s a step-by-step breakdown of the solution:Step 1: Understand the Concept of Electron Shells</
Has a -1 charge 3. Has a mass about the same as that of a proton 4. Is att The nucleus of an atom consists of which particles? Name three subatomic particles found in the atom of an element. If an atom has 17 electrons, 20 neutrons, and 19 p...
a有 但是 是坏的 But has is bad[translate] a也就是说铁元素原子核中的中子与质子要比其它所有元素原子核中的中子与质子靠近得更紧密,其中子与质子间的强相互作用力也最大,因而当其向同一个方向排列时,其也具有最大的磁场。 In other words, in the hard element atomic nucleus neutron and the proton ...
The Modern Theory of Atomic Structure: Atomic number: The number of protons in the nucleus of an atom of that element. –Gives the number of electrons in a neutral element. –Gives the order of elements on the periodic table –If an atom gains or loses a proton it not only changes its...
Hint: Each of the ions has a different number of protons, but each has one electron, so the Bohr model How many electrons in an atom can have each of the following quantum number or sub level designations? n=4, l=3A certain element has its outermost elec...
Which of the three are most important in determining what element an atom is? Which of the three are most. Matter – Properties and Changes Introduction to Natural Products Chemistry Cells of organisms - plants, fungi, bacteria, lichens, insects, animals - produce a large variety of organic. ...
An element may have more than one isotope, which are atoms with the same number of protons and electrons. They have different numbers of neutrons. For example there are three isotopes of hydrogen, H-1, H-2, and H-3 having 1, 2, or 3 neutrons. ...
