How is the chemical symbol of an element determined quizlet?
How is the chemical symbol of an element determined? Latin word, some of the first letter, location characteristics, people's names. What are atoms composed of? Are electrons, protons, or neutrons the smallest particles?
How many protons P and electrons E are found in a se2 − ion?
How many protons (p) and electrons (e) are found in a Se²⁻ ion? Se has an atomic number of 34, so it contains 34 protons. The neutral atom would have 34 electrons, but because the ion has a -2 charge, this indicates that there are two additional electrons.
What determines an elements atomic mass?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons.
How many electrons does an atom of 17o contain?
Answer and Explanation: In one atom of the oxygen-17 isotope, there are eight protons, nine neutrons, and eight electrons.
What determines the element type quizlet?
An element's location in the periodic table is largely dependent on its electrons; the number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element's block.
How is chemical symbol of an element determined?
chemical symbol, short notation derived from the scientific name of a chemical element—e.g., S for sulfur and Si for silicon. Sometimes the symbol is derived from the Latin name—e.g., Au for aurum, gold, and Na for natrium, sodium.
How many protons p and electrons E are found in a sc3+ ion?
Answer. The Sc3+ ion contains 21 protons and 18 electrons.
How do you find the electrons?
Finding the Number of Electrons The number of electrons in an atom is equal to the atomic number of an element, for neutrally charged species. This means the number of electrons and the number of protons in an element are equal. Therefore, the number of electrons in oxygen is 8.

How many protons neutrons and electrons are in 17o?
17O2− has 8 protons, 9 neutrons, and 10 electrons.
How is the identity of an element determined?
The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
What particle determines the name of the element?
Explanation: The identity of the element is determined by the number of protons, which are positively charged, massive nuclear particles. The number of protons in a nucleus is given by Z , the atomic number.
What element is E on the periodic table?
The elements of the periodic table sorted by name in an alphabetical list.
| Name chemical element | Symbol | Atomic number |
|---|---|---|
| Einsteinium | Es | 99 |
| Erbium | Er | 68 |
| Europium | Eu | 63 |
| Fermium | Fm | 100 |
What is the chemical symbol of N?
NNitrogen / Symbol
How do you find the number of protons and electrons in an ion?
The charge on the ion tells you the number of electrons. If the charge is positive, subtract that number from the atomic number to get the number of electrons. You have more protons. If the charge is negative, add the amount of charge to the atomic number to get the number of electrons.
How many electrons are in an element?
Finding the Number of Electrons The number of electrons in an atom is equal to the atomic number of an element, for neutrally charged species. This means the number of electrons and the number of protons in an element are equal. Therefore, the number of electrons in oxygen is 8.

What is the mass number of nitrogen 12?
Atomic mass of Nitrogen is 14.0067 u. Note that each element may contain more isotopes.
How many moles are in N?
The molar mass of nitrogen (N) is approximately 14.01 grams per mole of nitrogen atoms.
What is the element of N?
Nitrogen is a chemical element which has the symbol N and atomic number 7. Elemental nitrogen is a colourless, odourless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.1% by volume of Earth's atmosphere. Nitrogen, N, is an odorless, colourless, and tasteless gas.
In which isotope of oxygen out of o16 o17 and o18 there are equal number of protons electrons and neutrons?
Neutral isotopes of a certain element (like oxygen isotopes O-16, O-17 and O-18), contain the same number of protons (16, which defines them as oxygen atoms) and the same number of electrons.
Which element has an atomic number of 8 mass number of 16 and 10 electrons?
If we know the atomic number (8), we can subtract that from the mass number to determine the number of neutrons. 16O2− has 8 protons, 8 neutrons, and 10 electrons. 17O2− has 8 protons, 9 neutrons, and 10 electrons.
What isotope has 11 protons and 12 neutrons?
Sodium has 11 protons and 12 neutrons.
Which of the following is an element answer?
Sulphur is made up of only one kind of atom. Therefore it is an element. Other are compounds.
How do you identify an element?
There are two properties that can be used to identify an element: the atomic number or the number of protons in an atom. The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in question.
What is the role of E in an atom?
Electrons give the atoms the volume, shape etc. Without the electrons, the atoms will be positively charged. Without the electrons, the atoms cannot form bonds with each other.
Which element has an atomic number of 12?
Magnesium Magnesium – Element information, properties and uses | Periodic Table.
What is element name?
Before a name and symbol are approved, an element may be referred to by its atomic number (e.g., element 120) or by its systematic element name. The systematic element name is a temporary name that is based on the atomic number as a root and the -ium ending as a suffix.
