In chemistry class Roberto sees that traces of lithium makes a flame appear bright red's.?
In chemistry class, Roberto learns that when lithium salts are heated, they emit a bright red flame due to the excitation of lithium atoms. When these atoms absorb energy, their electrons move to higher energy levels and then release that energy as light when they return to their original state. This characteristic red flame is a key identification feature used in flame tests to detect the presence of lithium in various compounds.
What element has 3 protons and 3 electrons?
The only element with three protons is lithium.The isotope lithium-6, has 3 neutrons and is the rarer of the two stable isotopes of lithium.Most lithium is isotope lithium-7, containing 3 protons, 3 electrons, and 4 neutrons. It makes up about 92.5 percent of the lithium found on Earth.
What happen to carbon atoms valence electrons when it bonds with other atoms?
When carbon atoms bond with other atoms, they share or transfer valence electrons to complete their outer electron shell. This sharing or transferring of electrons creates chemical bonds with other atoms, allowing carbon to form various compounds essential for life.
Where on the Periodic Table are atoms with 1 outer shell electron located?
Atoms with one outer shell electron are located in Group 1 of the Periodic Table, also known as the alkali metals. This group includes elements like lithium, sodium, and potassium. They are characterized by having a single electron in their outermost shell, which makes them highly reactive.
What can't you take with lithium?
You should not take NSAIDs (nonsteroidal anti-inflammatory drugs) with lithium, as it can increase lithium levels and the risk of toxicity. Additionally, dehydration, excessive caffeine intake, and low-sodium diets can also interact negatively with lithium.
Why does sodium fluoride have a higher melting point than lithium fluoride?
Sodium fluoride has a higher melting point than lithium fluoride because sodium ions are larger and have more electrons than lithium ions, resulting in stronger electrostatic forces between ions in the sodium fluoride lattice. This makes it harder to break the ionic bonds in sodium fluoride, requiring more energy to melt it compared to lithium fluoride.
Why is lithium less reactive than sodium?
Lithium is less reactive than sodium because it has a smaller atomic size and higher ionization energy. The smaller size of lithium atoms makes it more difficult for them to lose an electron compared to sodium, which results in lower reactivity. Additionally, the higher ionization energy of lithium requires more energy input for the removal of an electron, further reducing its reactivity.
What subatomic particle causes atoms to react?
Electrons cause atoms to react. Atoms react to achieve a filled valence shell, which for most elements is 8, but 2 for hydrogen, lithium, and berylllium, because having 8 valence electrons, or 2 for H, Li, and Be, makes the atoms stable.
How many sodium atoms make up the sodium element?
23 g of sodium metal will have 6.023 x 1023 atoms (or 1 mole of atoms)
Why is sodium more reactive than lithium?
Sodium is more reactive than Lithium because the metals of Group 1 become more reactive as we go down the group. The ionization energy of lithium is greater than the ionization energy of sodium, and thus sodium is more reactive.

What at the atomic level what makes elements reactive?
their atoms take,give,or share electrons with other atoms :)
How many valence electrons does lithium have?
Lithium has only one valence electron. A valence electron is an unpaired electron available for bonding with other elements. This makes lithium is a highly reactive element that can bond rapidly and often violently with any element having four to seven valence electrons (or with hydrogen).
Are having eight valence electrons makes atoms very reactive?
No, eight valence electrons completely fills the valence band and makes the atom inert. The most reactive atoms have either one valence electron or seven valence electrons.
What atom has 3 protons and 3 neutrons?
An atom of lithium isotope 6Li has 3 electrons and 3 protons and 3 neutrons.
What makes a substance magnetic?
Magnetic objects must contain atoms with unpaired electrons. No unpaired electrons=no magnetism.
Lithium Ion has how many electrons and protons?
When you say Ion you have to specify whether its negative or positive and the number associated with it. For example: if its Li 3- it means it has 3 more electrons then regular Lithium (which has 3 electrons) that makes it 6 electrons and 3 protons (this nr doesnt change) for Li 3-. Obviously calculations vary depending on the type of ion.
