what is the atomic number of an element with 10 protons 11 neutrons and 10 electrons course hero

What is the number of protons in the element number?

The periodic table is arranged in order of increasing atomic number, so the number of protons is the element number. For hydrogen, the number of protons is 1. For zinc, the number of protons is 30.

How many protons and electrons are in a neutral atom?

For a neutral atom, the number of electrons is the same as the number of protons. Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge.

What element has 2 protons and neutrons?

The element of an atom with 2 protons is always helium. If you are given the atomic weight of an atom, you need to subtract the number of neutrons to get the number of protons.

What is the number of protons and neutrons in hydrogen?

For hydrogen, 1.008 is closer to 1 than 2, so let's call it 1. Number of Neutrons = Mass Number - Number of Protons = 1 - 1 = 0 For zinc, the atomic weight is 65.39, so the mass number is closest to 65. Number of Neutrons = 65 - 30 = 35

What is the atomic number of an element with 10 protons 11 neutrons and 10 electrons?

Neon is an atom with atomic number ten. Its atomic weight is 20.179 which cause it to have ten neutrons and ten protons in its nucleus and ten electrons outside.

What is the mass number of an atom that has 10 protons and 11 neutrons?

For neon, which has 10 protons, the mass numbers of the three different naturally occurring isotopes are 20, 21, and 22, corresponding to 10, 11, and 12 neutrons, respectively.

Which of the following is neutral atom would have 10 protons 11 neutrons and 10 electrons?

What neutral atom would have: 10 protons, 11 neutrons, 10 electrons? Neon, the Atomic Number is 10 and 10 on the periodic table is Neon.

What element has 11 protons 11 neutrons and 10 electrons?

Mass number We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass). Sodium has a mass number of 23amu.

What is the atomic number and the mass number of an atom of an element with 11 protons and 12 neutrons?

Detailed Solution Example: A sodium atom contains 11 protons and 12 neutrons; its mass number is 23.

How do you find the atomic number?

The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. For example, in a sodium atom, there are 11 electrons and 11 protons. Thus the atomic number of Na atom = number of electrons = number of protons = 11.

What element has 11 protons 11 neutrons?

The element with 11 protons is sodium Na. The sum of the protons and neutrons is the mass number, A, and is equal to 22.

What is the atomic number of an element with 10 protons?

Answer and Explanation: The atomic number is defined by the number of protons an atom has. Thus, since this element has 10 protons, its atomic number is 10, and the element...

What is the total number of neutrons in the nucleus of a neutral atom that has 19?

19 protons, 20 neutrons and 18 electrons.

What is the name of the atom that has 11 protons and 10 electrons?

sodium ionThe particle that contains 10 electrons, 11 protons and 12 neutrons is a positively-charged sodium ion (Na+).

What is the relationship between an atom containing 11 protons 11 electrons and 11 neutrons and other atom containing 11 protons 11 electrons and 12 neutrons?

What is the relationship between an atom containing 11 protons, 11 electrons and 11 neutrons, and another atom containing 11 protons, 11 electrons and 12 neutrons? As the number of electrons and protons are the same but the number of neutrons is different, these atoms are isotopes of each other.

What is the overall charge of an atom with 11 protons and 10 electrons?

If sodium loses an electron, it now has 11 protons, 11 neutrons, and only 10 electrons, leaving it with an overall charge of +1.

What are the protons, neutrons, and electrons in an atom?

Key Takeaways: Number of Protons, Neutrons, and Electrons. Atoms are made of protons, neutrons, and electrons. Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral. A neutral atom has the same number of protons and electrons (charges cancel each other out).

Which atom has the same number of protons and electrons?

A neutral atom has the same number of protons and electrons (charges cancel each other out).

How many protons does a hydrogen atom have?

It's easy to get a hydrogen atom with one proton and one neutron (deuterium), yet you won't find a helium atom with an atomic weight of 2 because this would mean the helium atom had two protons and zero neutrons! If the atomic weight is 4.001, you can be confident the atom is helium, with 2 protons and 2 neutrons.

How to find the number of neutrons in an atom?

You can find the number of neutrons if you know the isotope of the atom. Simply subtract the number of protons (the atomic number) from the mass number to find the remaining neutrons.

How are elements defined?

Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton (ionized hydrogen).

Why is the periodic table decimal?

Each atom has an integer number of neutrons, but the periodic table gives a decimal value because it is a weighted average of the number of neutrons in the isotopes of each element. So, what you need to do is round the atomic weight to the nearest whole number to get a mass number for your calculations.

What does it mean when an ion has a 2+ charge?

If an ion has a 2+ charge, like Zn 2+, this means there are two more protons than electrons. If the ion has a 1- charge (simply written with a minus superscript), then there are more electrons than the number of protons. For F -, the number of protons (from the periodic table) is 9 and the number of electrons is:
